铜坑锡矿东盘区采场的稳定性监测

Monitoring of Stope Stability in East Panel in Tongkeng Tin Mine

铜坑锡矿 91#矿体东盘区开采条件复杂 ,为确保矿体安全而高效回采 ,采用了以声发射监测技术为主的综合地压监测手段 ,对采区的稳定性进行了监测。根据监测结果 ,确定了东盘区合理的空区处理措施 。

The mining conditions of the east panel of 91# orebody in Tongkeng Tin Mine are fairly complicated so that the stability of mining areas is monitored in a comprehensive way with sonic-emission monitoring technique as a major ground pressure monitoring means so as to ensure the safe and highly effective of mining the orebody.Based on monitoring results,some proper measures were worked out for dealing with the mined-out areas in the east panel,thus realizing the highly effective recovery of the orebody.
