摘要
针对短壁开采工艺与装备在复合顶板条件下适应性差、配套不合理的问题,在安家岭井工二矿边角煤顶板存在风氧化煤的条件下设计了24206短壁开采工作面,并针对实际回采过程中发生的冒顶压架事故,分析了其产生原因,提出了预防措施,有效的解决了复合顶板条件下边角煤的回采问题。
Aiming at the poor adaptability and unreasonable matching in process and equipment of shortwall mining under composite roof, the 24206 shortwall mining face was designed in Anjialing No. 2 underground mine, with effloreseent and oxidized coal in roof of boundary coal. During mining, the process and equipment were adjusted based on the complicated geological condition of this area, the difficulty in boundary coal mining under composite roof was solved.
