TECHNICAL FIELD

[0002] Microseismic monitoring technology is a real-time, dynamic and continuous geophysical monitoring method for studying the structure and stability of coal and rock by using microseismic information generated by the rupture of coal and rock. It is widely used in mines with rock burst disasters and is one of the main means for monitoring and early warning of rock burst disasters in coal mines. By accurately positioning the energy size and source location of the rock burst activity during the mining process of the coal seam, the risk of rock burst and the source of rock burst can be evaluated. With the development of microseismic monitoring technology at home and abroad, the source parameters such as the plane position, time of occurrence and magnitude of the earthquake can be accurately obtained. However, the vertical positioning of the source is still a difficult problem in the field of seismology.
