The invention relates to coal industry and can be used to reduce the dust-forming ability of coal seams.

The purpose of the invention is to increase the effectiveness of reducing the dust-forming ability of coal mines by ensuring deep saturation with its hardness.

The goal is achieved by the fact that the composition additionally contains ethyl alcohol in the following ratio of components, wt.%: Syntanol DS-10, 30 Ethyl alcohol 6.00-9.00 Else

In order to obtain the optimal composition of the days of the proposed composition, mixtures with various contents of the input S1X in their components were tested. The results of the tests are shown in the table.

As a result of research, the optimal composition was selected. For the coal grades T, OS, K and F it contains May.%:

Sintanol DS-10 0,25 Ethyl alcohol 8,0 K Steelful

The process of injection of the proposed composition into the coal seam is carried out as follows. .

A hole is drilled into the coal seam from the surface or from the mountain wells and sealed with yctbe. Prepared in a separate container.

composition, which is pumped into the coal seam using a pump unit (unit). Ethyl alcohol in the proposed composition fulfills the role of an accelerator of penetration of this composition into the fracture-pore structure of coal;

Example. It is necessary to hydroprocess the coal seam,

Mining operations in the treatment area should come in 5-6 months. Processed reservoir g with a capacity (h) of 1.3 m, effective porosity (p) 4% refers to specific dust removal

to the category of very pshnyh. Coal

To treat the formation, wells are drilled from a haulage (walker) parallel to the surface of the clearing face. The length of the well along the coal seam (with a lava length of 190-210 m) is 150-170 m. One ... .. well is treated with 8 1500-1700 m. The amount of solution injected into the well will be;

.Or 8-L-Pe 78-88 m. The solution of the optimum composition is prepared in a separate container at the place of production of the hydrotreatment of the formation. The consumed number of components will be, t: Sintanol DS-10 0.195-0.22 Ethyl alcohol 4.93-5.56 Water71.6-80.7
