Study on Monitoring and Early Warning of Key Ground Pressure Disasters in a Tungsten Mine Combined Open-pit and Underground Mining
A tungsten mine has formed the open-pit and underground combined mining,which is faced with the key problems of ground pressure disaster,such as the stability of goaf and isolation pillar,the stability of open-pit slope and the interaction between open-pit mining and underground mining.Ground pressure monitoring and early warning systems,such as 66-channel micro-seismic monitoring system,measuring robot and slope radar,are designed and constructed.A typical successful early-warning case of unstable collapse of rock mass is introduced in detail.The above-mentioned comprehensive ground pressure monitoring means will provide important technical support for mine safety production.
