通过宏达煤矿保护层选择、本层与邻近层瓦斯预抽和卸压拦截抽、采空区抽采等防突与防灾研究,实现了强突出煤层群安全生产,解决了强突出煤层群不能采取上保护层或下保护层时首采工作面瓦斯治理这一世界性难题,提供了瓦斯灾害严重的突出矿井实现安全生产的又一有效方法。
Through the research on the selection of protective layer of Hongda coal mine, prevention and control of gas pre-pumping and pressure-relief intercepting pumping and gob recovery in this layer and adjacent layers, it has realized the safe production of strong outburst coal seams and solved the problems of strong outburst coal seams Can not take the upper protective layer or the lower protective layer when the first mining face gas treatment of this worldwide problem, providing a serious gas disasters highlight the mine to achieve another safe and effective method of production.
