【摘要】 简述我国煤矿事故的原因,总结地球物理方法在煤矿采空区和溶洞中的应用。详细分析采空区和溶洞的地球物理特征,利用高密度电法浅部探测能力强,尤其对低阻敏感的特征,并结合具有较深探测能力的浅层地震反射,查明工区采空区和溶洞分布特征、充水情况和裂隙的发育程度。更多还原

【Abstract】 The paper briefly describes the reason of the accidents in coal mining of China and summarizes the geophysical exploration method in the coal mine caves and goaf.It makes use of the strong ability of the shallow detecting in high density resistivity,especially in lower resistivity.In addition,it makes out the distribution features of goaf and caves and filling water conditions in combination of shallow seismic reflection with deeper detecting ability.更多还原
