摘要
开采厚煤层时,综采工作面的采高较高,因此,顶板容易出现严重的冒落带,煤壁出现片帮问题。鉴于此,本文探讨了其顶板垮落与煤壁片帮机制,在此基础上,阐述了控制围岩稳定性的方法,希望能够为有效控制类似围岩提供一定的帮助。
During mining thick coal seam, the mining height is generally higher, the surrounding rock stability is relatively poor, prone to occur severe roof caving and coal wall spalling. In view of this, this paper discusses the roof caving and coal wall spalling mechanism, on this basis, expounds the stability of the surrounding rock control method, hoping to provide some help for the effective control the surrounding rock.
