摘要: 结合格目底矿区玉舍中井突出煤层群开采的实际情况,从开采保护层的角度,探讨消除煤层突出危险性的方法。结果表明,单一选择上或下保护煤层均无法对中部主要可采煤层进行充分泄压,采用K9煤层和K40煤层作为联合保护层同时开采,可达到对中组煤层进行双重叠加保护的目的,从而消除煤层突出危险。
关键词: 突出煤层群, 保护层, 突出危险性, 双重叠加保护
Abstract: Combing the actual mining situations of coal seams group of the Yushe middle well of Gemudi mining area,the methods are discussed so as to eliminate the outburst dangers of coal seam from the perspective of the mining protection coal layers.The research results show that,the upper protection coal seams and lower protection coal seams are unable to relief the pressure of the central minable seams fully.The K9 and K40 coal seam are taken as the protection coal seams so as to conduct the double stack protection of the middle coal seams and eliminate the outburst coal seams dangers by mining at the same time.
Key words: Outburst coals seams group, Protection coal seams, Outburst dangers, Double stack protection
