综合物探在小窑采空区勘查中的应用研究

Research on Application of Comprehensive Geophysical Prospecting in Coal Goaf Exploration

为了解整合煤矿上覆小窑采空区的分布情况,指导矿井下组煤层的安全生产工作,总结分析了小窑采空区的地球物理特征和常用地球物理勘查方法。采用瞬变电磁法和高密度直流电法进行联合勘探,对晋中南地区浅埋区小窑采空区进行勘查。利用多种方法勘探结果的综合分析,基本查明了小窑采空区的分布情况,并对其含水性进行了分析,通过与已知采掘资料的对比,表明综合物探在本次勘查中取得了良好的勘探效果。

In order to investigate the distribution of goaf in integrated coal mine and guide the safe production of coal mine, the geophysical characteristics and common geophysical exploration methods of goaf are summarized and analyzed. Transient electromagnetic method(TEM) and high density electrical method(HIGH-DENSITY electrical method) are used to explore the goaf of shallow buried coal mine in south Shanxi Province. Based on the comprehensive analysis of multi-method exploration results, the distribution of minedout area of small kiln is basically found out, and its water content is analyzed. Compared with known mining data and verified by drilling work, it shows that comprehensive geophysical exploration has achieved good results in this exploration.
