东欢坨矿软岩巷道围岩矿压显现规律研究

摘要

东欢坨矿矿压显现非常强烈，给支护管理带来了很大困难。以2088工作面为例，根据煤层情况和地质条件，对顶板破裂状况进行了测定和分析，对支护体变形规律进行了探讨，并对顶板深部位移情况进行了研究，得出了顶板深部离层规律，为支护的设计和优化提供了科学依据。%The rock pressure is very obvious in Donghuantuo Colliery which brought a lot of difficulties for sup‐porting management .According to the coal situation and the geological condition of 2088 face ,the author first determined and analyzed the roof broken situation ,then discussed the deformation law of the support ,and final‐ly probed into the deep displacement of roof and obtained the law of roof deep separation ,w hich provided scien‐tific basis for the design and optimization of roadway supporting .
