Activity Rules of Earthquake Induced Coal Mining in Northern Shaanxi

Abstract:

Study on the unique activity rules of earthquake induced by coal mining (EICM) is the foundation of earthquake prevention and disaster reduction. Based on the record data of EICM in northern Shaanxi from 2009 to 2012,the time-space distribution rules of seismic events is investigated by statistical methods; the trend of activities is predicted by analysis of magnitude-frequency relationship and creep curves sequence of EICM; the formation mechanics is discussed by using energy principle, the results show that: the corresponding relationship between EICM and on-site mining activity patterns is obvious, with the coal mining scale and depth increasing, EICM is inevitable, caused by the roof fall collapse, its intensity (the maximum magnitude of possible is 4.4) and frequency will increase further in the next period of time.
