Analysis and Advance Detection of Coal Mine Water Hazard Factors

为了优化煤矿采区的水害超前探测效果,以水害要素分析为基础,结合瞬变电磁法和地震法探测优势,提出了一种精细、全面的水害超前探测技术。结果表明:采用此探测技术能提前查明巷道前方煤岩层的赋水性及构造发育情况,实现多种探测信息的多元互补,分析探查区域内水害要素关联性和发育变化,综合评估煤岩层采掘前后的水患威胁性,优化探测效果,确保煤矿安全生产。

In order to optimize the effect of advanced water damage detection in coal mining areas,based on the analysis of water damage factors,combined with the advantages of TEM and seismic detection,a detailed and comprehensive advanced exploration technology is proposed.Results show that the water-bearing capacity and structural development of the coal strata in front of the roadway can be ascertained in advance by using this technique to achieve multiple complementarities of various detection information.By analyzing the correlation and development changes of water hazard factors in the region,comprehensively evaluating the threat of water hazards before and after the mining of coal strata,optimize the effect of exploration,and ensure the safety of coal mine production.
