【摘要】 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。更多还原

【Abstract】 According to the survey data about impact of strong mining earthquake in Hegang Coalfield on the ground,and the elliptical attenuation theory of earthquake intensity,the attenuation relationship of mining earthquake intensity along long axis and short axis directions was calculated regressively,and intensity attenuation model of mining earthquake for Hegang Coalfield was established using the elliptical attenuation model.Based on the mining earthquake intensity attenuation relationship,the earthquake intensity in meizoseismic area under maximum ML 4.2 mining earthquake and its impact were discussed.更多还原
