综合物探探测煤矿采空塌陷区
MINE GOAF SUBSIDENCE TROUGH PROSPECTED BY COMPREHENSIVE GEOPHYSICAL EXPLORATION
【摘要】 简述了煤矿采空塌陷区的形成及影响,论述了高分辨地震法、α卡法和钻孔弹性波CT法的地球物理基础,并对此3种物探方法的使用效果进行了比较,还列举了综合探测的应用实例
【Abstract】 The formation and influence of subsidence area by mined out are described briefly,and the geophysical base of the high resolution seismic survey,the emanation determination method and the in hole elastic wave CT method are expounded.The application and effects of these three geophysical methods are compared,citing the application examples of the comprehensive survey.
