| 英文摘要 | In a sublevel caving mine, mining-induced hanging wall failure violently threatens the mine safety production. In this study, a high precision microseismic (MS) monitoring technique was adopted to investigate the stability and failure mechanism of the hanging wall with complex geological structures. Research results show that micro-fracturing process was controlled by a combined mechanism of tension and shear, in which tension mechanism dominates micro-fracturing process. Intensive fracturing development finally manifested as MS event clusters, that can serve as an indicator of the boundary of the hanging wall global failure. Then roof collapse boundary (RCB) investigation in the hanging wall roadways was carried out to verify the availability of this indicator. Through analysis combined with rock mass structure, micro-fracturing process and hanging wall global failure were obviously affected by the major group of steep inclined joints. Moreover, if hanging wall global failure extended to a fault, the hanging wall failure will change the previous way and instead developed vertically and rapidly upward along the fault, resulting in collapse pits on the surface ground. The activation and collapse of the fault will break the connection between both sides of the fault, shielding movement and deformation propagation to the deep rock mass. Therefore, the deformation of deep hanging wall had significant hysteresis characteristics. |
