Micro-seismic positioning method

The invention relates to the technical field of coal mine safety production and discloses a micro-seismic positioning method. The positioning method comprises the following steps of obtaining the average speed of a vibration wave on a current detection working surface by manually setting test vibration, then calculating to obtain a three-dimensional coordinate of a test vibration source according to the detected micro-seismic first arrival time, error correction on positioning being carried out according to an error between a calculated value and an actual value, and finally qualified calculation coordinates being obtained. The method has advantages of accurately calculating the micro-seismic source and carrying out three-dimensional simulation on micro-seismic. 本发明涉及煤矿安全生产技术领域，公开了一种微震定位方法，通过人工设置试验震动得到振动波在当前检测工作面的平均速度，然后根据检测到的微震初至时间，计算得到试验震动源的三维坐标，并通过计算值与实际值的误差，来对定位进行误差校正，最后得到合格的计算坐标。本方案具有能精确计算微震震源并对微震进行三维模拟的有益效果。
