Research on Comprehensive Monitoring and Early Warning Technology of Deep Ground Pressure in Chambishi Copper Mine
The deep ground pressure activity in the southeast ore body of the NFCA Qianbixi Copper Mine is frequent,and affected by the aquifer above the roof,the production risk is greater.In view of the complex geological conditions of the southeast ore body,a scheme was proposed to comprehensively monitor the deep ground pressure of the southeast ore body by combining conventional ground pressure monitoring methods and microseismic monitoring methods,the accuracy and reliability of ground pressure monitoring early warning were improved.The results show that:The ground pressure activity near the interval column is relatively strong,mainly affected by surrounding production disturbances,but the amplitude is not significant;The results of microseismic monitoring are consistent with those of conventional ground pressure monitoring,and microseismic monitoring can perceive ground pressure activity about 2 days in advance,which has a certain degree of foresight;Combining conventional ground pressure monitoring with microseismic monitoring can improve the accuracy and reliability of ground pressure monitoring and early warning,and the comprehensive monitoring method can ensure the safe production of mines to a certain extent.
