为提高微震监测系统计算得到震级的准确性，研究了微震监测系统计算震级和能量的方法，采用最小平方法对微震监测系统的震级－能量关系式参数进行了优化。以华丰煤矿数据为例，采用最小平方法计算得到的震级－能量关系式参数a， b分别为3.484，2.123。采用新参数得出的震级与地震台提供震级比较接近，从而验证了最小平方法优化震级－能量关系式参数的可行性。

In order to improve magnitude accuracy calculated by micro-seismic system, the method of calculating magnitude and ener-gy in micro-seismic system was researched.Applying minimum square method to optimizing parameters of magnitude-energy relationship formula and taking data from Huafeng Colliery as calculation example, the parameter a and b of magnitude-energy relationship formula was calculated to be 3.484 and 2.123 with minimum square method.The magnitude calculated with new parameters was near to that from seismic-station, which proved its feasibility of optimized magnitude-energy relationship parameters.
