采用网络并行电法仪探测采煤工作面无煤区

The Application of the Network Parallel Galvanic Exploration System on the Surveying of Whole-Rock Area in Coal Mines

介绍了网络并行电法仪的基本特点,并采用网络并行电法仪来探测煤矿工作面内全岩区域的范围,用以指导工作面的采煤。探测结果表明,网络并行电法仪可以用于直流电法探测,对于工作面内全岩区域的探测采用温纳四极法和高分辨地电阻率法反演都取得了明显的效果。多装置视电阻率反演的综合解释既提高了资料解释的可靠性,也体现了网络并行电法仪的优势。

The fundamental features of the network parallel galvanic exploration system are introduced. The surveying of whole-rock area within the coal working face in Xieqiao Coal Mine is presented and used to guide the coal production. It was testified that the new-type electrical exploration system can be used in DC electrical surveying, both interpretations of high-density resistivity methods and high-resolution earth resistivity survey are effective for the exploration of the whole-rock area. The integration of different surveying methods not only improves well reliability and precision of prospecting results, but also embodies the advantages of the network＇parallel galvanic exploration system.
