摘要
淮南矿业集团公司潘一矿2662(1)上风巷掘进期间,其斜上方2622(3)综放面正在回采,为解决开采动压影响问题,采用锚索网联合支护的方式,提高了巷道的整体抗压和抗变形能力,取得了良好效果。
During the drifting＇ s period of 2662（ 1 ）tailentry at Panyi coal mine HuaiNan, upside it the 2663 （3） longwall with top- caving mining is working. In order to solve the problem of mining dynamical pressure＇ effect, adopts the method of blot - beam - steel mesh support system. Improves the ability of whole resist compression and resistance to deformation, it has obtained very good results.
