中文摘要：

为高质量地完成高速公路下伏浅层小煤窑采空区的勘察，通过现场踏勘测量、高密度电法结合浅层地震的综合物探法进行采空区勘察试验，初判下伏采空区的深度、范围及工程特性；后在相应位置钻探对综合物探法推测结果进行查证。勘察结果表明，综合物探法与钻探结合可更详细查明采空范围或采空塌落的影响范围的分布情况，为设计提供准确资料。

英文摘要：

To investigate goaf areas of Small Coalpits beneath highway, site survey and high-densi- ty electrical method combined with integrated geophysics of shallow seismic are supposed to preliminarily judge depth, range and characteristics of the goaf. And then drill at the corresponding locations according to the preceding survey datum. The results show that the integrated geophysical method combined With drilling is more effective in identifying the distributions of gob scope and its collapse scope.
