小窑破坏范围及积水区探查综合物探技术应用研究

Study on application of comprehensive geophysical prospecting technologyfor small kiln damage area and water accumulation area

基于坤达煤业井田范围内三、四采区3号煤层小窑开采的实际情况,分别采用三维地震方法对小窑分布范围、瞬变电磁法对小窑富水性进行综合探查,基本查明了小窑分布范围和积水范围,三维地震和瞬变电磁法可以互为验证和补充,为矿井的生产布局和安全生产提供了可靠依据,同时,综合物探技术的应用也为未来的煤矿勘探和开采提供了新的思路和方法。

Based on the actual situation of small kiln mining of No.3 coal seam in the third and fourth mining areas of Kunda Coal Industry,the distribution range of small kilns and the water richness of small kilns were comprehensively explored using 3D seismic methods and transient electromagnetic methods,respectively.The distribution range and water accumulation range of small kilns were basically identified.3D seismic and transient electromagnetic method can be used to verify and supplement each other,which provides a reliable basis for mine production layout and safe production,the application of integrated geophysical prospecting technology also provides new ideas and methods for future coal mine exploration and mining.
