摘要
由于矿井地质条件复杂,采煤工作面往往布置有老巷道,且巷道位置关系比较复杂,为使采煤工作面安全通过其回采范围内的老巷道,本文针对赵楼煤矿5301综放工作面中间巷的位置关系,提出针对性的过老巷措施,有效控制了工作面顶板,保证工作面过老巷安全回采,为今后工作面过老巷提供了技术参考。
Because of the complex geological conditions of the mine,the old tunnels are often arranged in the coal mining face,and the location relationship of the tunnels is relatively complex.In order to make the coal mining face pass through the old tunnels within the mining area safely,this paper put forward the pertinent measures for the old tunnels in the middle tunnel of 5301 fully mechanized top-coal caving face of Zhaolou Coal Mine and effectively controls them.The roof of the working face ensures the safe mining of the working face through the old tunnel,and provides a technical reference for the future working face through the old tunnel.
