为有效分析焦作矿区矿压显现规律,规范煤巷支护管理,从松软顶板厚度、不同巷宽和不同埋深3个角度对焦作矿区松软顶板煤巷进行数值模拟计算分析,总结出了松软顶板煤巷围岩变形特征规律。
In order to effectively analyze the rule of mine pressure in Jiaozuo Mining Area and to standardize the support management of coal roadway, the numerical simulation of soft roof coal roadway in Jiaozuo mining area is conducted from three aspects of soft roof thickness, different lane width and different buried depth. Deformation Feature Law of Surrounding Rock in Coal Roadway.
