摘要
叙述了马兰矿的工作面参数概况及18303皮带巷掘进与18305回采情况,分析了18303皮带巷前后两段支护形式及其不同的支护效果和原因分析,并指出其经济效益。旨在分析探讨回采动压范围内送巷支护参数。
This paper described working surface profile parameters and belt roadway tunneling of 18303 and mining situation of 18305 in Malan Coal Mine, analyzed two supporting forms before and after roadways of 18303 belt roadway,as well as the effect of different supporting and the cause analysis, and pointed out its economic benefits with the aims to analyze roadway bolting parameters within the scope of mining dynamic pressure.
