摘要
在短壁高效综合机械化开采巷道掘进过程中,考虑到回采工艺对巷帮支护的特殊要求,大胆改革创新,首次选用可回收锚杆对巷帮进行支护,经济效益和社会效益相当可观。可回收锚杆在东山煤矿的成功应用值得地质条件相类似的矿井借鉴,对可回收锚杆在煤矿中推广应用具有重要意义。
In the process of high efficiency combined mechanicalization tunnelling in shortwall drift,considering the special requirement of tunnel flitch timbering,firstly use recoverable anchor pin to timber tunnel flitch which can get great economic and social benefits.The successful application of recoverable anchor pin in Dongshan coal mine is worth using for reference for similar geologic condition shaft,which for spreading application of recoverable anchor pin in coal mine is with the important significance.
