摘要
在新建的新集八里塘煤矿井底车场巷道所进行的巷道围岩应力及力学性质的套筒致裂法现场测试研究，以及井巷支护工作状况的分析是本文的主要工作。本文阐明了急倾斜煤系岩层中巷道地压的特点，介绍了巷道围岩应力及力学性质的测试结果，分析了八里塘煤矿－２００ｍ回风水平提升井马头门及井壁出现裂缝的原因，讨论了适应于急倾斜煤层开采的巷道支护型式。
AbstractAuthor's main research work are rock mass stress and rock properties insitu measurement using sleeve fracturing technique, carried out atshaft-bottom of a new constructed Balitang Colliery in Xinji, and miningstructure work state analysis. This paper describes the feature of rockpressure acting on roadway and presents the results from rock mass stressand rock properties measurement , analyzes the reason of concretefissuration in shaft-lining and inset of Hoisting Shaft, and discusses theroadway support type which is suitable for steep coal bearing strata.
