薄煤层缓倾斜破碎顶板下停采技术

Broken Down Gently Inclined Thin Seam Roof Stop Mining Technology

综采工作面薄煤层缓倾斜破碎顶板端面冒顶是影响安全和生产效率的重要原因。通过对其内外因素进行分析,采取相应措施加强顶板的控制,为防止在停采期间冒顶事故的发生提出见解。同时,对停采期间的破碎顶板支护技术进行分析、回采工艺和安全措施进行研究,对撤架的破碎顶板支护技术进行探讨。

The working face gently inclined thin coal seam broken roof cave-end face is an important reason affecting the safety and productivity. Through analysis of its internal and external factors, to take appropriate measures to strengthen the control of the roof to prevent roof collapse during a stop mining accidents presented insights. Meanwhile, the broken roof support during stop mining techniques to analyze the recovery process and safety measures research on withdrawal broken roof rack support technology were discussed.
