摘    要:随着煤矿开采深度增加,综放开采回采巷道易发生冲击地压危害。研究综放工作面回采巷道冲击地压发生机理,结合工程实例,运用FLAC^3D软件模拟综放面回采。分析了采用卸压措施前后煤层顶底板及两帮煤体移动变化规律、深部煤岩体受栽及变形破坏规律、煤层应力变化及转移规律。研究结果对防治冲击地压有一定参考价值。

关 键 词:综放开采  冲击地压  应力集中  数值模拟

Abstract:With the increase of the depth of coal seams mined, rock bursts will easily occur in gateways with fully-mechanized sublevel caving mining. The mechanism of rock bursts occurred in gateways, combined with engineering practice, is studied and the mining in fully-mechanized sublevel caving mining faces is simulated by using the software FLAC^3D. The law of movement and variation in surrounding coal seam, the law of deformation and failure in deep-seated coal seams and rock bodies under loading and the law of change and shift of the stresses in coal seams before and after adopting the measure of pressure relief by blasting to coal seams are analyzed. The result of research will benefit the prevention and treatment of rock bursts.
Keywords:fully-mechanized sublevel caving mining  rock burst  stress concentration  numerical simulation
