依据鹤岗煤田强矿震对地面影响的调查资料及地震烈度衰减理论,采用椭圆衰减模型回归计算了沿长轴与短轴方向矿震烈度的衰减关系。建立了鹤岗煤田矿震烈度衰减模型,应用矿震烈度衰减关系,讨论发生最大震级ML:4.2矿震的极震区地震烈度及其影响。
According to the survey data of the influence of strong mining on the ground in Hegang Coalfield and the attenuation theory of seismic intensity, the decay relationship between the intensity of the earthquakes along the major axis and the minor axis is calculated by ellipse regression model. The seismic intensity attenuation model of Hegang coalfield is established. By using the relationship between the intensity of mineralization and seismic intensity decay, the seismic intensity and its influence of the maximum seismicity with ML: 4.2 earthquake are discussed.
