鹤岗煤矿开采诱发地震研究

对鹤岗煤矿开采诱发地震的生成环境、活动与破坏特征及震源机制进行了分析，提出鹤岗矿震的孕育和发生受到人为采掘因素和区内构造应力场的双重作用。在特定的构造物理条件和地球动力学环境下，深部采矿使井下断裂构造从稳定状态逐渐活动或蠕动，致使局部活化。矿震具有震源浅、对地表破坏强的特点。震源机制表现出断层的运动方式有走滑断层，也有正断层和逆断层。

Research on induced earthquakes by coal mining in Hegang

With regard to mining-induced earthquake in Hegang Coal Mine, the formation environment activity, destructive characteristics and source mechanism were analyzed. Resuct shows that the pregnancy and occurrence of the earthquake was affected by both man-made mining and tectonic stress field in coal mine area. Under specific tectonic condition and geodynamic environment, the mining in the deep pit makes the rupture struclure active or creep from stable state. Mining-induced earthquake has features such as shallow source and serious destruction. Source mechanism shows that the fault movement includes slip fault, normal fault and reverse fault.
