煤矿采空区勘查设计技术研究

Research on exploration and design technology of goaf in coal mine

为了核实紫晟煤业矿区范围内资源储量情况,以紫晟煤业地质概况为基础,采用收集资料、井下实测、瞬变电磁法、钻探、地球物理测井等方法查明2号煤层采空区范围及分布情况,分析了多项技术的工作方法及技术要求,不同技术相互补充和协同,提高了煤矿采空区探测精度。研究可为下一步采空区探测、资源储量核实提供可靠技术支持。

In order to verify the resources and reserves in Zisheng Coal Mining Area,based on the geological situation of Zisheng Coal Industry,the scope and distribution of No.2 coal seam goaf were identified by collecting data,underground measurement,transient electromagnetic method,drilling,geophysical logging and other methods.The working methods and technical requirements of various technologies were analyzed.Different technologies complement and cooperate with each other to improve the detection accuracy of coal mine goaf.The research can provide reliable technical support for the next goaf detection and resource reserves verification.
