我矿是一个急倾斜煤层产量占很大比重的矿井。解放后在党的正确领导下,曾对急倾斜采煤方法进行了一系列的改革,由落垛式采煤方法改成水平分层采煤法、综合采煤法、斜切分层采煤法、平板掩护支架采煤法,换向采煤法等等,一直到现在经常用的是伪斜柔性掩护支架采煤方法。这种采煤方法从一九七○年开始试用,由刚开始2～3米长的梁,发展到5～7米、7～9米,薄煤层也有了1.3米左右的架子。从架型来看,有“—”字型、字型、字型、对接梁、加强梁和双柔性掩护支架等。这种采煤方法对增加产量、提高效率、降低消耗
Mine is a mine whose steep coal seam has a large proportion of production. After the liberation, under the correct leadership of the party, a series of reforms have been carried out on the method of steep coal mining, from stowage coal mining method to horizontal stratum mining method, integrated mining method, bevel staged coal mining Law, flat-screen shield mining method, to the mining method, etc., until now is often pseudo-oblique flexible shield mining method. The coal mining method has been piloted since 1970, from the beginning of 2 to 3 meters long beams to 5 to 7 meters and 7 to 9 meters. Thin coal seams also have shelves of about 1.3 meters. From the frame point of view, there are “-” fonts, fonts, fonts, butt beam, beam reinforcement and double flexible shield bracket. This mining method to increase production, improve efficiency and reduce consumption
