摘要
通过分析研究回采巷道锚杆支护发展过程中出现的诸多新问题,作者认为,为使锚杆支护在回采巷道中得到恰当地应用,必须对大量的新锚杆和新机具加以系列化、规范化;并在多年试验研究的基础上,就回采巷道中锚杆类型、锚杆直径和施工机具等系列化、规范化提出了一些建议。
Through studying some new questions existing with development of application of bolt support in back mining strata, author think that new bolt and construct tools must been standardized so that the bolt support can been used in back mining strata appropriately. Some suggests on series & standardization for bolt type and bolt diameter and construct tool are presented in this paper on the basis of many years trial research.
