摘　　要：在总结某煤矿9101大倾角综采工作面滑移规律的基础上,利用UDEC数值模拟软件研究底板无支护宽度、底板岩性和支架工作阻力与底板破坏滑移的影响,分析底板滑移的控制因素大小,并提出软岩底板破坏控制技术。研究结果可为大倾角煤层底板支护提供科学依据,实现煤层安全高效开采。On the basis of summing up the sliding law of 9101 fully mechanized coal face with large dip angle in a coal mine, UDEC numerical simulation software was used to study the influence of the width of floor without support, the lithology of floor, the working resistance of support and the failure sliding of floor, analyze the control factors of floor sliding, and put forward the failure control technology of soft rock floor. The research results can provide scientific basis for floor support of large dip angle coal seam and realize safe and efficient mining.
