摘　　要：新汶矿业集团翟镇煤矿大采高孤岛采场通过优化巷道围岩和采场上覆岩层控制措施,改进生产工艺,顺槽巷道掘进期间采用锚带网加锚索的联合支护方式,回采期间超前支护采用悬移支架,上下端头采用切顶支架,采场采用俯采、调采、配合割通刀的生产方式推进,实现了安全高效生产。Through optinaization of roadway surrounding rock and the control of overlying strata in isolated island working field with large mining height in Zhaizhen Colliery of Xinwen Mining Group Co. , Ltd. , the paper dis- cusses the production management mode of driving crossheading roadway by combined support with bolt--mesh --cable, stoping by advanced support with movable support, upper and low end with edge support, and advan- cing mining field by down--dip mining and adjusting mining together with cutting--off tool, which realizes safe and efficient production and provides a reference for complicated mining field management.
