摘要
为解决近距离开采和特殊地质条件下巷道变形及回采期间顶板控制难题,以沙坪煤矿1811运输巷为研究对象,在巷道压力集中区时采取了矿用11~#工字钢抬棚支护、顶帮帮锚索加密支护和马丽散注浆加固等巷道维护技术,取得了良好的顶板控制效果,有效地预防了顶板事故的发生,对于类似煤矿近距离开采顶板控制和维护具有重要的指导意义。
In order to solve the problem of roof deformation under the close mining and special geological conditions and the roof control during the mining,the 1811 transportation lane of Shaping Coal Mine is taken as the research object,in the roadway pressure concentration area,the mining 11~#I-beam steel shed support,the roof maintenance technology such as roof-rib anchoring cable support and Marithan grouting reinforcement are adopted,which has achieved good roof control effect,effectively preventing the occurrence of roof accidents,and has important guiding significance for the close-range roof control and maintenance of coal mine.
