斜沟煤矿3号煤层覆岩结构综放开采顶板涌水量预测研究

Research on roof water inflow prediction of overburden structure fully mechanized caving in No.3 coal seam of Xiagou Coal Mine

覆岩结构综放开采顶板渗水现象仍然为煤矿生产主要制约因素之一。以斜沟煤矿3号煤层为主要研究对象,通过对覆岩结构综放开采裂隙分布规律研究以及覆岩结构综放开采涌水量数值分析,实现对覆岩结构综放开采顶板涌水量的预测,以期对矿井水害防治研究有所帮助。

The seepage phenomenon of roof in fully mechanized caving mining with overlying rock structure is still one of the main restricting factors in coal mine production.Taking the No.3 coal seam of Xuegou Coal Mine as the main research object,through the research on the crack distribution law of fully mechanized caving mining with overburden structure and the numerical analysis of the water inflow in the fully mechanized caving mining with overburden structure,the prediction of the water inflow in the roof of fully mechanized caving mining with overburden structure is realized,which is expected to be of some help to the research of mine water disaster prevention and control.
