中国科技论文在线 平四矿近距离煤层群上行开采支架适应性 分析 张富军，马立强* 5 （中国矿业大学矿业工程学院，徐州 221008 ） 摘要：由于生产条件的变化，平四矿出现了接替紧张的生产局面，为了缓和接替紧张的生产 局面。为了减少煤炭资源损失，多回收煤炭资源，延长矿井服务年限的目标，平四矿决定对 己16,17 煤层采空区上方原本遗弃的己 15 薄煤层实行近距离煤层群上行薄煤层综采。为了 10 解矿压的显现规律和工作面支架选型是否合适，对己 15-23020 工作面进行了现场实测，通 过矿压数据综合处理系统对测站内各支架的工作阻力数据进行分析，得出己 15-23020 工作 面的支架工作期间的压力分布规律，液压支架额定工作阻力有较大的富裕，支架的支护性能 适应该地质条件下煤层开采的要求。 关键词：上行开采；压力观测；支架选型 15 中图分类号：TD823 Bracket Ascending Mining Seams Adaptability in PING No.4 Mine ZHANG Fujun, MA Liqiang 20 (School of Mines,China University of Mining and Technology,XuZhou 221008) Abstract : Since changes in production conditions, PING NO.4 Mine production appeared tense situation to succeed, in order to ease the tension take over the production situation. In order to reduce the loss of coal resources, coal resources and more recycling, the goal to extend the service life of the mine, PING NO.4 Mine decided to JI16, 17 Coal Seams in the top of the original 25 abandoned JI15 thin coal seams to implement uplink Thin Seam Mining. Mine appeared to understand the law and face pressure is adapted to support the work of resistance, on the face JI15-23020 conducted a field measurement, data integration through the rock pressure on the station processing systems support the work of the resistance within the analysis of data obtained JI15-23020 during stand face to pressure law, the resistance of hydraulic support rated greater 30 prosperity, performance support bracke
