回采工作面采空侧巷道矿压显现规律

Rock Pressure Behavior of Goaf Roadway in Mining Face

针对目前煤矿采空侧工作面巷道存在的矿压显现剧烈及巷道变形量大的问题,通过现场设站实际观测和后期的数据归纳分析,得出工作面回采巷道矿压显现的规律。并对回采面采空侧巷道变形的动态规律和影响范围作出定量分析,为以后工作面设计合理巷道断面和生产过程中的顶板管理提供一个量化的依据。

In view of the problems of severe mine pressure behavior and large tunnel deformation in the roadway of coal mining side face at present, the regularity of mine pressure behavior in mining roadway is obtained through the actual observation on the spot and the data induction and analysis in the later stage. The dynamic law and influence range of roadway deformation in goaf face are analyzed quantitatively, which provides a quantitative basis for the reasonable roadway section design and roof management in the process of production.
