摘要
结合阳邑煤矿极近距离煤层同采的具体条件,采用理论计算及现场矿压实测的方法,分析了阳邑煤矿极近距离煤层不同错距下同采的可行性及矿压显现规律。结论表明,大青与下架工作面合理错距保持在20~25m范围内,更有利于同采工作面采场及巷道的维护。生产实践表明稳压区开采方案是安全、合理及可行的。
Combined with actual condition of Yangyi Colliery,theoretical calculation and underground pressure observation was used to analyze the feasibility of simultaneously mining 2 faces in extremely-near coal seams and underground pressure behavior rules.Results showed that the rational separation distance of 2 mining face was 20-25m which was favorable for keeping mining-field and roadway stable.Practice showed that the mining project was safe,rational and feasible.
