构造应力与矿区地震

北票矿区是浅源地震的多发矿区。为研究地震机制，以地质动力区划方法查明的活动断裂为区域构造格架，将矿区简化成由１０条断裂组成的弹性平面模型，编制了计算软件。结合地震波方法，得出了１级断裂所形成的区域应力场是北票矿区地震的主要成因，断裂面失稳滑动是地震的主要表现形式，矿区开采则是地震的诱导因素的结论。

Techonic Stress and Mine Earthquakes

Beipiao Mine is a mining area in which shallow earthquakes often take place to study mechanism of these earthquakes,this paper series free faults founded out by geodynamic division as regional techonic framework,it simplifies the mine into an elastic plan model with 10 faults and gives calculation stress software.According to the principle of earthquake wave,it concludes:regional strees field formed by Fault I is the major origin of earthquakes in Beipiso Mine.the slumping of the fault are main manifest of earthquakes and mining is leading factor of ear thquakes.
