摘要
通过实验室相似材料模拟试验,分析了近距离采空区下进行采煤,上覆岩层的破坏状况和支承压力分布规律,以及顶板冒落和采动裂隙发育的特征。分析了上覆岩层来压规律对煤炭开采过程中的安全影响,以此为在采空区下安全采煤防止上覆岩层裂隙水的侵入提供有效的理论和实践上的依据。
Through the analog stuff simulation test in lab, analyse the destroy situation of overlying strata and the law of abutment stress distribution, and analyse the character of roof fallen and mining cranny growth. Analyse the safety influence of the law of overlying strata pressure to the coal exploitation, so provide the effective bases of the theory and practice for the safety mining coal under close quarters goal, and prevent the cranny water of overlying strata inrushing.
