摘要
保护层开采是突出矿井区域防突最有效、最经济的措施,更是实现突出矿井安全生产的根本保证,尤其是下保护层开采后大量被保护层(1层或多层)瓦斯充分解吸通过裂隙涌入开采保护层采空区,保安煤业多措并举彻底解决了回采工作面采空区、邻近层、本煤层的瓦斯问题,取得了很好的实效。
Protective seam mining is the most effective and the most economic measure for region outburst prevention of outburst mine, especially in the fundamental guarantee for safety production of the outburst mine. Mter mining lower protective layer, the full desorp- tion gas in a large number of protective layer （ a layer or multi - layer） rushes into the gob of the mining protective layer through cracks. Bao^n coal industry completely solved the gas problems in the gob of stope, adjacent layers and the mining - coal seam, and a- chieved good effectiveness.
