摘要

Usage: gornodobyvayuscha industry, underground mining, dangerous to sudden outbursts of coal and gas, the technology of gornopodgotovitelnyh workings. SUMMARY OF THE INVENTION: during excavation mixed slaughter slaughtering of drilled holes, they are sealed, the hydraulic fluid is injected into gidrootzhima mode determined cases dissolved zone size with the maximum concentration of stress, the holes of the coal seam drilled to a depth b bi + b where bi - unstable bed size; L2 - size of the stable part of layer stopper through breed drilled production wells intersecting the seam area of ​​maximum stress concentration and injected into 0,1 jH g 0,3 JH with the borehole fluid pressure, but not exceeding 0,5 jH, wherein the mean density of the rock; H-generating depth positioning, injecting derivative T until the array extendible toward expose coal. 1 ZP f ly-2-yl.
