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。可回收锚杆在五阳煤矿的成功应用值得其他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 course of short wall mining, considering the particular demand of roadside support, we have got the great economic benefit and social benefit by using recoverale bolt in roadside support. The gelolqic conditions simifar to Wuyang coal mine can use the technology. This has a great significance to extend and apply this technology.
