48705综采工作面顶板管理与超前支护技术研究

Study on Roof Management and Advance Support Technology of the 48705 Fully Mechanized Mining Face in Ximing Coal Mine

西铭矿48705综采工作面巷道顶板为灰岩、页岩结构,层理、裂隙明显发育,易出现顶板冒落,顶板管理难度较大。利用理论分析与物理计算相结合的方法对该工作面的顶板管理与超前支护方法进行分析研究,并提出了有效的支护监测方法,为该矿顶板管理与顶板事故的预防工作提供了参考。

The roof of 48705 fully mechanized mining face in Ximing Coal Mine is limestone and shale structure. The bedding and fissures are obviously developed, and roof caving is easy to occur. Roof management is difficult. Based on the combination of theoretical analysis and physical calculation, the roof management and advanced support methods of the working face are analyzed and studied, and an effective support monitoring method is put forward, which provides a reference for roof management and prevention of roof accidents in the mine.
