With the advance of coal mine deep mining, water disaster in goaf and fracture zone gradually becomes an important safety hazard, which may cause accidents such as collapse and roof fall. The fracture zone formed by rock damage caused by mining activities becomes a channel for groundwater flow, increasing the risk of water disaster. Traditional detection methods have limitations and cannot fully cover and may damage the mine structure, so it is necessary to develop efficient and non-destructive detection technology. The device should have high precision, real-time, non-destructive and strong adaptability, etc. It can accurately monitor the water flow in the fracture zone. With the progress of sensor, remote sensing and other technologies, the comprehensive application of new technologies such as seismic wave, electromagnetic wave and laser scanning has become an effective tool for coal mine water disaster prevention and control.
