    Abstract:

    In this paper,the combined mechanism of mining tremors is discussed and a reasonable combined point-source mechanism with its solution is proposed in consderation of decomposi-tion of interior source's moment tensor,that means inversion of relative moment tensor by theuse of first motion amplitudes which is valuable for us to distinguish double-couple events and non-double-couple events.
    Fifteen tremors observed in Mentougou Mine in 1987 are studied in simplified way,as a result most of them are double-couple events.
