摘要
针对巷道施工前上方可能存在采空区积水的现象,佳新能源采用武汉地大华睿地学技术有限公司研制的大功率瞬变电磁法对矿井行人斜井下段掘进工作面进行了超前探测研究和应用,为水害治理和煤层开采提供了物理探测技术依据。后期验证结果证明探测结果与实际基本吻合;瞬变电磁法在煤矿工程施工中的超前探测有一定局限性,有待于进一步提高资料处理的可靠性和准确性,具有广泛的推广应用价值。
Roadway construction and above ahead may exist the phenomenon of water-logged goaf,plus Jiaxin Energy adopted the mine transient electromagnetic method under pedestrian inclined section tunneling faces to carry on the research and application of advanced detection by Wuhan Didahuarui Company,provided the flood management and physical detection technology based on coal seam mining.The late coincided basically with the validation results showed that detection results coincided with the actual;transient electromagnetic method in advanced detection of coal mine construction limitations,remained to be further improve the reliability of data processing and accuracy and had wide popularization and application value.
