中文摘要：

地下采空区是一种潜在的地质灾害，需要查清其范围、深度和规模等，便于进一步治理。分析了地下采空区的地球物理特性和电阻率特征，利用HMEs技术对辽源矿山采空区进行勘探。圈定出地下采空区的范围。利用三阶二次B-样条插值函数对空间散列点进行曲面拟合，并将其应用到地下采空区的三维模拟中，效果良好。

英文摘要：

Mine goal as a potential geological disaster is required to be investigated thoroughly in its scope, depth and size for the future treatment of goaf. The physical geography properties and resistivity character of underground mine goaf were analyzed. An exploration to goaf in Liaoyuan coal mine was carried out with HMES and the area of the goaf was determined. With this meth- od, a 3D simulation of underground mine goaf was done, with good results.
