大采高伪斜综采面老顶分段初次来压分析与控制

Analysis and control on segmentation first weighing of main roof of fully mechanized pseudo-inclined mining face with large cutting height

针对大采高大倾角伪斜综采面初采期间老顶分段初次来压的矿压显现规律,结合工作面具体的地质生产条件及初采期间老顶破断特征,分析了大采高伪斜综采面老顶呈现分段初次来压的原因,并提出了相应的支架—围岩稳定性控制措施。

This paper aims at the strata pressure behaviour law of segmentation first weighing of main roof on the fully mechanized pseudo-inclined mining face with large cutting height and angle during the initial mining period,it analyses the causes of segmentation weighing strata behaviours in the large cutting oblique working face,based on its specific geological production conditions and the roof breaking features during initial mining period,then,the corresponding control measures of support-surrounding rock system stability are put forward.
