ANALYSIS OF THE CAUSES OF MICROSEISM INDUCED BY UNDERGROUND MINING-TAKING A MINE IN BEIPIAO MINING AREA AS AN EXAMPLE
A mine in Beipiao mining area is one of collieries which are exploited deeper than others in our country. As a result, mining induced microseismicity has happened 1550 times since 1971. The microseismicity is called mine seismicity because most of them take place in the mining area. Mine seismic events happen mostly in geological structure zone and mining area, and are characterised by shallow focus, strong intensity, comparatively concentrated focus and so on, and their occurrence is periodicity. There is a close relationship between mine seismicity and many factors such as regional earthquake activities and mining activities. In this paper, based on the research of mutual relationship of geological structure, ground stress, mining conditions and characteristics of mine seismicity, it is concluded that Taiji mine seismicity is induced by mining activities under the regional stress field. The characteristics and laws of the mine seismicity are analyzed.
