摘　　要：由矽卡岩白钨矿、铅锌铜硫化矿组成的宝山多金属矿床,经过几十年的开采在260中段以上存留有大量矿柱,其中501、542北区6~11线3个保安矿柱的回采难度最大,为此制订了有效的中深孔深孔崩落法试验回采方案,在矿柱周边布置地压监测孔,用地音仪和光应力计对矿柱及周边空区应力集中部位实施地压监测,及时分析监测数据并采取相应的安全回采措施,成功实现了矿柱安全回采。Plenty of ore column are left above 260 for the Baoshan polymetallic deposit,which are made up by skarn scheelite copper,lead and zinc sulfide ore after decades of mining. Among them,extraction is the most difficult at the three security ore column of 6 ~ 11 line in 501,542 north district,the effective extraction scheme of medium-length hole and longhole caving mining method test are developped. Ground pressure monitoring hole are layout surrounding ore column,geophone and photoelastic stressmeter are arranged to monitor the gound pressure stress meter to land at the stress concentration areas of ore column and its empty area. The monitoring data are analyzed in time and corresponding measures are taken to ensure safety mining,safety extraction for ore column are successfully implemented.
