摘　　要：细脉带矿体遗留的大量房间矿柱,由于受火区与空区隐患的困扰,回采条件极其困难。分析了该矿体的开采技术特点,针对性地采用高效率束状大孔大范围整体崩落采矿方法,同时系统地采取柔性阻波墙、均匀出矿、地表覆盖等安全控制措施,解决了复杂隐患区内矿柱群回采的技术难题,同时达到了根治火区隐患的目的。There are hidden safety trouble due to fired area and mined - out area in the stringer lode zone of Tongkeng Mine, so it is very difficult to recovery the ore pillars in this area. In this paper, the mining technical characteristics are analyzed. The complex technical problems of mining the pillar group which is left in the hidden danger area are solved by applying high efficiency block - forced caving method with cluster large drilling holes blasting and such safety measures as flexible shockwave re- sistance wall, even ore drawing and covering in collapsed area, fi- nally the purpose to eliminate hidden safety troubles in the fired area has been achieved.
