Abstract

Abstract: In this paper, basedon the analysis of geological tectonics, mining status, me-teorologic data and mine tremorrecords in Laohutai coal mine, Fushun City, China, some fundamentallaw regarding mine tremors' activity in Laohutai coal mine is summ arized. The results show that the timedistribution of mine tremor is mostly affected by mining status, suchas method,depth and intensity. The results also show that the frequency dis-tribution of mine tremors inone year has negative correlation with the rainfall. Under the current exploitation condition, the mine tremors' activity shows an enhancemental tenden-cy. The location of mine tremors is mainly controlled by the large faults and structures in the mining area.

Key words: Mine tremor, Activity law, Laohutai coal mine, Sequential feature, Geologi-cal tectonics
