Abstract

Based on the geological structure of Yima coalfield and working face 21221of Qianqiu Mine as the engineering background, this paper designs a similar simulation experiment of fault slip instability under the influence of mining, and explores the characteristics of the influence of coal slicing mining disturbance on fault slip instability law.The results show that because the upper layer of the coal seam has caused a large degree of loosening and separation of the roof, when the lower layer of the coal is mined, the original loose roof rock further collapses, so the lower layer of the coal is mined Disturbance triggers a larger collapse range of the overlying rock mass, which makes the displacement changes around the fault become more intense, and the phenomenon of upper and lower disk displacement is more obvious.The strain energy peak accumulated in the coal rock mass is larger; at the same time, the fault slip is relatively lagging behind the violent release of strain energy in the rock mass of the coal, so the"sudden drop"phenomenon of the peak strain energy can be used as a precursor to judge fault slip and instability; the violent release of energy in the lower layer mining is earlier than the upper layer mining, and it is easier to induce the occurrence of rock-burst disasters.
