Abstract

Through the analysis of the gas control effect of the mine protected layer, it was shown that the combination of surface drilling and downhole through-layer drilling can solve the problem of pressure relief gas emission of the protected layer and avoid the gas overrun accident in the working face of the protected layer, but the two extraction methods have mutual influence and the gas control cost is larger. On the basis of field investigation on the drainage radius of surface drilling, the layout of through-layer drilling was optimized, and It is put forward that the pressure relief gas of the protective layer is controlled by the way of surface drilling drainage and through-layer drilling drainage, which reduced the cost of gas control, realized the efficient and safe mining of protective layer, and had certain guiding significance for mine gas control under similar conditions.
