摘要
燕子山矿4#层首采面回采过程中,因矿压显现过大造成支架顶梁、立柱损坏等问题,通过分析燕子山矿4#层矿压显现规律,对支架重新进行选型,加强初撑力管理等措施,保证了后续工作面的顺利回采。
During the mining process in the first mining face of No. 4 coal seam in Yanzishan Mine, in view of theproblems that the top beam and column of the support were damaged due to the overlarge behavior of mine pressure, byanalyzing the behavior law of mine pressure in the No. 4 coal seam of Yanzishan Mine, the support type was reselectedandthemanagementofinitial supportforcewas strengthened, they ensuredthe smooth mining of the followup work surface.
