摘要
目前大多数综采工作面矿井仍使用单体液压支柱作超前支护,虽然少数大型矿井采用了端头支护液压支架,但仍存在支护长度短、中间通道窄、体积大运输移动不便等问题,使用履带行走式超前支护液压支架可完全解决这些问题,且在支护的过程中它不存在二次支护造成的对顶板锚杆锚索破坏的问题。
Most fully mechanized working face in mines is still using the single hydraulic prop shoring, although a few large nfine adopts the end hydraulic support, the supporting length is short and intermediate channel is narrow, large volume transportation is inconvenient. Crawler type advanced hydraulic support can fully solve these problems, and also avoid damage on roof bolts and anchors by secondary support.
