一、采场护顶措施概述铜录山铜铁矿是大冶有色金属公司重点生产矿山之一,设计规模为4000(吨/日),其中井下生产能力为1600(吨/日)。目前井下开采集中在Ⅲ、Ⅳ号矿体,矿体和围岩受断层破坏,节理发育,裂隙交错又受地下水侵蚀,尤其受矽卡岩带穿插,矿体完整性差,顶 I. Overview of stope roof protection measures Tongshanshan copper and iron mine is Daye Nonferrous Metals One of the key production mines, the design scale of 4000 (tons / day), of which downhole production capacity of 1600 (tons / day). At present, the underground mining is concentrated in the ore bodies of No. Ⅲ and No. Ⅳ. The ore body and the surrounding rock are damaged by the faults, the joints are developed, the fractures are interlaced and eroded by the groundwater, especially intercalated by the skarn zones. The integrity of the ore bodies is poor and the top
