(57) Abstract:

The invention relates to mining and can be used for mining with backfill. The invention improves the quality gidrogelatorov array by reducing its shrinkage when used as an additional backfill material rubber waste. The method of construction of filling the array in the developed space chamber when the development system includes separate transportation Solodov and additional backfill material and placing them in the exhaust chambers. The mined-out space is carried out at separate transportation Solodov and additional backfill material, in this case, initially placed on the soil camera rubber waste, and then erect it hydrosalinity an array of slothdom. 1 Il.

The invention relates to the mining industry and can be used in the development of minerals chamber systems with a mined-out space.

Known methods of hydrobalance using as backfill material waste ores, for example the moves (Borzakovskiy B. A. , Paulov L. M. Backfilling operations at the Verkhnekamskoe potash mines. - M - Depths. - 1994. - S. 92-101).

However, these methods provide significant shrinkage of filling the array and, accordingly, increase hydrosilation works.

Closest to the proposed invention is a method of laying-out space in the chamber system development sloping potash seams. C. 1244354, MKI E. 21 F 15/00, publ. in BI 26, 1986). This method provides for separate transportation of the primary and secondary backfill material, and as an additional backfill material used sand.

The disadvantage of this method is the difficulty (complexity) of the process of obtaining and placing additional backfill material if there is a substantial shrinkage of the filling material.

The technical result of the invention is to improve (increase) the quality of the backfill array by reducing its shrinkage and reduced environmental burden on the environment during the use of rubber waste as an additional backfill material.

This technical measuring the development system consists of separate transportation of Solodov and additional backfill material, placing them in the waste cells, and as an additional backfill material use of rubber waste, which are initially placed on the soil chamber, and then erect it hydrosalinity array.

As an additional backfill material use of rubber waste, which can be represented, for example, second-hand automobile tires, conveyor belts, air bags, scraps of rubber, seals, etc., While hydrosilation pulp fills all the gaps that exist in the bulk rubber waste, improving the quality of the backfill array.

The essence of the method is illustrated in the drawing, which shows a General scheme bookmarks camera.

The method is as follows. Initially, additional backfill material, which is used as rubber waste 1, is transported to put the camera first on the trunk, and then along the horizontal mine workings, for example, on the truck tractor and placed in bulk 2 in the waste chamber 3.

1 waste on the ground lay the camera unloaded in bulk without stacking. In the presence of the th, as the required amount of rubber waste will be placed in the chamber 3, through the hole 4 in the seam parting in laying the camera serves the pulp and namyvayut hydrosalinity salt 5 array.

However, the array only from rubber waste has a large number of voids due to their complex volume and loose styling. As a consequence, such an array will have a large shrinkage, which would entail a reduction in the strength of the backfill array.

Thus, to realize the benefits of rubber waste as an additional backfill material, it is necessary that the waste was completely surrounded by filling the array. This condition is most easily implemented when using as primary backfill material slurry from slothdom. The slurry fills the voids between the separate rubber products, and voids in the products.

Rubber waste is used as an additional backfill material, durable, mine when the temperature is not subject to disintegration, stand in contact with the salts. Rubber compression practically does not change its volume. The above listed properties of rubber apply the backfill material is due to the fact, that rubber under compression does not change its volume. This means that the shrinkage laying array will be reduced in proportion to the amount of rubber waste in the total volume of backfill array. So, for example, put an array of colodado under the influence of rock pressure has a shrinkage of 10%, if the array will consist of 10% of rubber waste and 90% Solodov, the shrinkage rate is 9%, i.e., will be reduced by 10%.

The use of rubber waste as an additional backfill material increases as backfill array by reducing its shrinkage as rubber compression practically does not change its volume. In addition, the use of rubber waste to bookmark reduces the environmental burden on the environment.

The method of construction of filling the array in the developed space chamber when the development system, including separate transportation Solodov and additional backfill material, placement them in the exhaust chambers, characterized in that as an additional backfill material use of rubber waste, which are initially placed on

SUBSTANCE: method includes erection of rows of main platforms along bed length in staggered order with length equal or divisible by step value for support displacement, and placing filling material thereon. Along length of main platforms between ceiling and bed soil post support is mounted, upon which filling material is fed. After that between main platforms additional platforms are erected with wedge supporting, and main platforms are rotated counter-clockwise towards pneumatic support and it is displaced for one drive step. During that filling material, while lowering, unwedges wedge support between ceiling and bed soil and forms artificial supports. After that additional platforms are rotated counter-clockwise towards pneumatic support. After movement of cleaning face for two drive steps operations for constructing artificial supports are repeated. Distance between main platforms along bed fall line are selected from mathematical expression.
