综合物探方法在大宝山矿采空区勘察中的应用效果探讨

Application of Comprehensive Geophysical Prospecting to Dabaoshan Mining Cavities

矿山的采空区,尤其是不明采空区对矿山的采矿施工构成严重的安全隐隐,对矿山的不明采空区进行全面勘查是保证矿山安全的重要手段。本文通过大宝山矿已知采空区和勘查区的几种物探方法的测量结果,提出了高密度电法和浅层地震纵波反射法对采空区的勘查具有较好的勘探效果。通过对物探成果资料和地质资料的对比研究,总结了采空区异常的识别方法,最后总结了各种方法的优缺点,提出了今后对采空区勘查工作方法的建议。

The mining cavities, esp. the unknown mining cavities cause serious damage to the mining construction, so it is important to make a complete exploration of the unknown mining cavities. This paper points out that the high - density electric method and shallow seismic reflection method have a better effect on the exploration of mining cavities. Comparing the geophysical data with the geological data, it generalizes the methods to identify the abnormal phenomenon of mining cavities and sums up their advantages and disadvantages. Finally, it pu.ts forward some suggestions for future exploration work.
