New Drainage Tunnel Will Be Commenced at an Early Date
Drainage Tunnel—It is reported that the new drainage tunnel will be commenced at an early date. It will be started about 3 miles below the mouth of the present tunnel in Cripple Creek canon. It is the intention to run the tunnel straight to El Paso shaft, cutting that shaft at a depth of something over 1,300 ft. From El Paso shaft the tunnel will make a turn and run directly toward the Vindicator mine.
graphic for visual presentation of text A tunnel of this depth will drain the district for many years to come.

Info Title:
Drainage Tunnel Financing Issues
Denver, Sept. 15—A more or less serious obstacle in the financing of the construction of the new drainage tunnel at Cripple Creek is the fact that a number of the mine owners on the east side of the district seem to be inclined to withhold their contributions until assured that their mines will be drained, since it may be three years before the Portland mine will be reached.
graphic for visual presentation of text About $550,000—of the necessary $750,000—has been subscribed and the plan is to engage the services of a prominent engineer to explore the course of the tunnel and make recommendations in regard to its construction.

Drainage Tunnel Location Might Change
Drainage Tunnel—The immediate commencement of the new drainage tunnel is again being talked of. In all probability a number of other surveys to determine the most feasible place to construct the bore will be begun at once. Considerable has already been done on this line.
graphic for visual presentation of text Until recently it has been understood that the tunnel would be constructed in Cripple Creek gulch, but now there is some talk of driving from Wilson Creek gulch.
graphic for visual presentation of text It is understood that D. W. Brunton, the well-known mining engineer, will probably be retained as consulting engineer for the tunnel.
graphic for visual presentation of text The principal idea of the location of the tunnel is to find a site which will be the most beneficial to all the mines concerned. The new tunnel will undoubtedly be constructed by all of the mines in the district, and will be under the supervision of the Mine Owners' Association.

New Drainage Tunnel Legal Stuff
Denver, Dec. 1—As the projected large drainage tunnel will necessarily be of greater benefit to the properties through which it runs, than to such as are located some distance from its route, and some properties might be involved in litigation with intervening owners while trying to connect with the tunnel, provision will undoubtedly be made in the contracts for such contingencies, and this matter is at present being considered by the projectors.

Deep Drainage Tunnel to Happen Soon
Denver, Colorado.
graphic for visual presentation of textDrainage Adit.
graphic for visual presentation of text With the announcement of the intention of the mine owners to begin driving the deep drainage adit another note of encouragement is sounded. This adit is to have its portal in Gatch Park at an elevation of 8,020 ft., or 753 ft. lower than El Paso, the lowest of existing adits, and will go far to solving the water problem. It is expected to drive it to the main water course — a distance of 15,550 ft. — in two years.
graphic for visual presentation of text It is then planned to continue it to the Vindicator shaft, giving a total length of 27,190 ft. This distance is to be driven in five and a half years, at a cost of $721,000. The mine owners are, wisely enough, raising a fund of $1,000,000 for this purpose.
graphic for visual presentation of text D. W. Brunton is the consulting engineer, and, if his recommendations are carried out, the adit will be 7 ft. wide by 10 ft. high, and have a grade of one foot in 300. The heading is to be driven in both directions from a shaft 10,000 ft. from the portal and diamond-drills are to be used to hasten the work. Ventilation will be obtained by the use of positive blowers.

New Drainage Tunnel Happenings
Cripple Creek, April 1. (Special Correspondence)—A corporation called the Cripple Creek Drainage & Tunnel Co. with a capital stock of 1,000,000 shares, par value of $1 per share, has been formed, with nine of the representative mine-owners of the Cripple Creek district acting as directors. This proposed tunnel will lower the water-level of the Cripple Creek district about 750 ft., and its portal is situated on the stream known as Cripple creek, and it is proposed to run it to a point near the El Paso mine, a distance of 15,000 ft., to cut the Beacon Hill water courses.
graphic for visual presentation of text If it is found necessary, it will be extended to a point near the Vindicator mine, a further distance of about 11,000 ft. It is estimated that the first section of about 15,000 ft. will cost in the vicinity of 1400,000 and will take from two and one-half to three years to construct.
graphic for visual presentation of text The mines, railroads, and other interested parties have subscribed for a sufficient amount of the capital stock at par to build the first section, and they propose to subscribe for a further amount, if it is found advisable to build the second section. The company is now engaged in constructing buildings and installing machinery and otherwise arranging for active work.

graphic for visual presentation of text The bids for the driving of the drainage adit at Cripple Creek have been opened and the lowest proves to be between $20 and $21 per foot. If this bid is accepted, it will make the total cost of the completed adit considerably over $500,000. The signal importance of this deep drainage adit is derived from the fact that it will tap the main watercourse 740 ft. below the present deepest drainage, opening reserves of ore that cannot now be reached.
graphic for visual presentation of textIts portal is in Cripple Creek canon, about six miles south of the town, and at an elevation of 8,020 ft.
graphic for visual presentation of textFrom there it will be driven in a northerly direction 14,500 ft. to the workings of the El Paso mine, and, probably, thence easterly 11,000 ft. to the workings of the Vindicator.
graphic for visual presentation of textThe funds for the work have been contributed by all the principal companies operating in the district.
graphic for visual presentation of textA shaft is likely to be sunk about 10,000 ft. from the portal, and the heading advanced both ways from this, which, with an average advance of ten feet per day in each heading, will permit the reaching of the El Paso workings in two years.

Deep Drainage Tunnel Contract Awarded Lund & Stream
Cripple Creek, Colorado.
graphic for visual presentation of textContract for Drainage Adit.
graphic for visual presentation of text The contract for driving the drainage adit has been awarded to Charles Lund and Charles Stream, and their $20,000 bond to insure the company against all liens has been approved. A rate of 350 ft. per month is to be maintained by the contractors, the adit to be 7 by 10 ft. in the clear. The Tunnel Company will furnish all timbers, pipe, and rails, as well as the necessary power. Seventy-five per cent of the amount due each month will be paid the contractors, the remainder to be withheld until the completion of the contract.
graphic for visual presentation of text It is proposed to sink an intermediate shaft from the surface at a distance of 9,000 ft. from the mouth. This shaft will be between 600 to 700 ft. deep and will materially decrease the time of driving the bore. A boarding-house to accommodate the employees has been started by Charles Lund, as the mouth of the adit is several miles from the town of Cripple Creek.

Roosevel Drainage Tunnel with Excellent Progress
Denver—At Cripple Creek the big producers have practically all stopped pumping and development, and are grubbing around in upper workings until the Roosevelt adit shall be completed and drain the ground.
graphic for visual presentation of text The 'tunnel' is making excellent progress. Since June, when the portal workings were connected with those on the intermediate shaft, there has been but one heading to push. A. E. Carlton, the contractor, has three shifts of men at work, and 410 ft. was accomplished in August.
graphic for visual presentation of text At this rate the tunnel should begin to drain the mines in about 15 months. It is expected that shortly after there will be a heavy production from the lower levels and that Cripple Creek will experience a new boom.

Roosevelt Tunnel Advances
Denver, Dec. 4—The Cripple Creek drainage tunnel during November was advanced 298 ft. The full distance driven to Dec. 1 is 11,705 ft. The heading has been driven over 700 ft. into the granite of Beacon hill, and its extreme hardness has prevented more rapid progress. No moisture is observable in the breast of the tunnel, so tight is the rock, but it is expected that one of the numerous dikes traversing this section may soon be encountered and with it a flow of water. The minor water course tapped last month continuous to flow at the rate of about 100 gal. per min., but the water is carried off in the ditch and in no way interferes with work.
graphic for visual presentation of text In anticipation of the results to be expected from the deep drainage tunnel, when the 3000 ft. of driving yet remaining is completed, properties on Beacon hill are making preparations to extend operations below the present water level.

Roosevelt Tunnel Making Progress
Roosevelt drainage adit is making excellent progress and is expected in eight or ten months to reach the water-filled breccia. If the flow encountered be only as large as in the El Paso (7000 gal. per min.), it may be expected that the waterlevel will be lowered at a rate of 6 to 8 ft. per month.
graphic for visual presentation of text Since at greater depth the head will be larger, the flow should also be faster and even speedier benefits may accrue. The water present in the district is estimated at 46 million gallons per foot of depth, the figures being based upon the discharge at the El Paso adit.
graphic for visual presentation of text To pump this would cost, according to records, $125 per million gallons, and would entail a continued and unknown cost to take care of surface waters. The anxiety, therefore, with which operators await the completion of the drainage adit can well be understood.

Denver, Sept. 1—Definite word has come that the Roosevelt drainage tunnel is to be extended. At a meeting of the directorate of the tunnel company, held in Colorado Springs, it was decided to drive the main head forward a distance of 1500 ft.
graphic for visual presentation of text The question of finances has been the principal point at issue in holding back work upon the further extension of the tunnel, but this matter is practically settled in the announcement that $27,500 of the $50,000 required has been subscribed and that the balance will shortly be secured.

Roosevelt Drainage Tunnel Talks About
Denver Sept. 8—Work on the drainage tunnel at Cripple Creek was stopped for want of funds but money is being raised for its continuation. There is some difference of opinion among the subscribers as to the future course. One party desires to continue the tunnel, which was stopped in the granite, straight ahead into the breccia area where the mines are, reaching that area somewhere close to the Elkton mine; the other party thinks it best to leave the main course, and develop a big water flow by following some of the dikes intersected. These dikes are in the granite.

Roosevelt Tunnel Still Drains
In 1907 the lowest of the numerous adits driven to secure drainage, the so-called Roosevelt tunnel, was started, and has been in progress ever since. Some months ago, the breast had reached a point at which it might have been expected to develop a large flow, but the results were disappointing. Those in charge of the enterprise persisted, however, and their persistence was finally rewarded, for during the last week of November, the two drifts on the C. K. & N. vein developed a flow of 5500 gal. per min., and the total flow from the adit is now nearly 9000 gal. per min., corresponding to a rapid decrease in the water-level of the district.
graphic for visual presentation of text The Battle mountain mines are being un-watered at the rate of 3.1 in. per day and the Portland has already recovered its 1500-ft. level, while the 1050-ft. level of the Stratton's Independence, flooded since 1907, has also been recovered.
graphic for visual presentation of text Production in the district will be greatly stimulated, and a "boom" is confidently expected.

Info Title:
Roosevelt Tunnel Keeps on Draining
The future of the Cripple Creek district now looks brighter because of the increased effectiveness of the Roosevelt deep-drainage adit, which is now draining the mining area at the rate of 82 ft. per month.
graphic for visual presentation of text The El Paso mine is dry to the drainage-adit level, which is 1338 ft. below the shaft collar, the Portland has recovered its 1500-ft. level, and the Independence its 1000-ft. station. This will make possible the mining of the deeper levels and, presumably, an increased production of high-grade ore.

Info Title:
Roosevelt Tunnel Illumination Method
Electric lamps is the type of Illumination chosen for the Roosevelt Tunnel.
graphic for visual presentation of text Electric incandescent lamps possess a number of advantages for tunnel work. They give a brilliant and steady light—one that is not affected by drafts and neither pollutes the air with soot nor vitiates it by consuming the oxygen. By combining several of them in a cluster, plenty of light in the heading is obtained for the drillers and shovelers, tending toward efficiency. To offset this advantage, however, the fact remains that unless they are used in connection with electric locomotives, drills, or similar machinery, the cost of lamp installation is almost prohibitive; even with the electric appliances in use the extra wiring and the lamps themselves are expensive, while the latter are subject to considerable loss through breakage. Electric lamps are also at a disadvantage because they are not easily portable and the removal and replacement of bulbs and wires in the heading before and after blasting complicate an already involved situation. Moreover, this means of illumination is uncertain, especially in wet tunnels, because the chance occurrence of a short circuit through moisture, accident, or carelessness throws the entire work in darkness, and if other means of lighting are not at hand, stops all work until the trouble can be remedied. Again, whereas the use of electricity under ground is always attended with some danger, this is especially true in the case of lighting appliances; the supposition is that the wires are protected, but the rough usage which they are subjected soon destroys insulation, rendering persons who handle them (as they must do frequently) subject to severe shock.

Info Title:
Roosevelt Tunnel Ammunition Used
The Roosevelt Tunnel used Gelatine as Kind of Dynamite Used, with a Strength of 40%, 60% and 100%.
graphic for visual presentation of text Gelatine dynamite is a combination of a certain amount of blasting gelatine (varying according to the strength desired) and a suitable absorbent. The former is made by adding a small percentage of gun-cotton (nitrocellulose) to liquid nitroglycerin, thus producing a jelly-like mass that has greater explosive qualities than either of its constituents, but which is much less sensitive to shock than nitroglycerine. The absorbent is usually some combustible material (wood pulp is frequently employed) to which has been added a sufficient amount of sodium nitrate to supply the necessary oxygen for its combustion. By the use of such a combustible absorbent, instead of the inert one formerly employed with straight nitroglycerine dynamite, the gases generated by the burning of the wood pulp add to the volume produced by the detonation of the explosive constituent, and the extra heat generated in this combustion adds greatly to the total intensity of the reaction.

Roosevelt Tunnel Facts
The Roosevelt tunnel may now be considered completed, as work has ceased with the heading in the centre of the Hawkeye claim of the Portland company. The total length of the tunnel from portal to breast is 24,355 ft., or 4.6 miles, and it is one of the longest in the United States.
graphic for visual presentation of text The Roosevelt tunnel has taken 11 years to drive and its cost has been $812,000. This sum includes sinking of an intermediate shaft 700 ft., and a raise of 160 ft. to connect with the Elkton main shaft, through which the tunnel is now operated. The average cost has been $33.30 per foot.
graphic for visual presentation of text The saving in pumping costs alone is conservatively estimated at $3,000,000.
graphic for visual presentation of text In 1918 two long drifts were driven from the tunnel, one of 1720 ft. to connect with the Cresson shaft; the other 2000 ft. connecting with the Portland No. 2 shaft, at a depth of 2133 ft.
graphic for visual presentation of text The flow from the tunnel has varied from 17.000 gal. per min. in 1906 to the present flow of 2500 gal. The district has been effectively drained, as not a mine is pumping.

Vindicator Considering Extending the Roosevelt Drainage Tunnel
Extension of the Roosevelt drainage tunnel from its present terminal on the Portland estate to the Vindicator Con. Gold Mining Co.'s No. 2 shaft, a distance of approximately 3000 ft., is under consideration by the Vindicator directorate. The estimated cost is between $100,000 and $150,000.
graphic for visual presentation of text Rich ore has recently been found in the Vindicator mine at a depth of 2000 ft., but the cost of raising water is heavy and eats up profits.

Info Title:
Roosevelt Tunnel Extension Plans
Negotiations looking to extension of the Roosevelt deep-drainage tunnel, some 3000 ft. distant from the Golden Cycle shaft, are under way, but no agreement has as yet been reached. The Vindicator Consolidated company is extending a lateral north-west from the 19th level of the Golden Cycle shaft, corresponding to what will be the 20th level of the Vindicator No. 2. The objective is the present terminal point of the Roosevelt deep-drainage tunnel.
graphic for visual presentation of text The extension of the tunnel rests with other companies owning property in the Bull Hill area, who are expected to contribute to the general cost, estimated at $80,000. The Vindicator company, however, will extend the deep lateral to its end-line at its own expense, and at the present time is draining the Bull Hill area, and it feels that property owners should contribute toward the tunnel extension through other than Vindicator holdings.
