Transmission Channel Wave Detection Technology of Coal Seam Thickness Variation

为解决工作面内煤层厚度变化对煤矿采掘部署、生产计划、采出率的影响问题,首先分析了煤层厚度变化的地质原因及主要探测手段;其次,在介绍槽波探测理论的基础上,采用3D正演模拟方法对工作面内部煤层厚度变化情况进行了研究,证明了透射槽波探测煤层厚度的可行性;最后,采用透射槽波探测技术对黄陵某矿工作面内部煤层厚度变化情况进行了探测,查明了工作面煤层厚度变化情况。探测结果表明透射槽波探测技术能够有效探查工作面内部的煤层厚度变化,为矿井安全开采提供有效技术支撑。

In order to solve the problem that coal seam thickness variation of working face to coal mine mining arrangement, productionplan, mining rate and so on. First, the geological reasons and principal detection method that caused coal seam thickness variationwere analyzed, secondly, based on channel wave detection theory, coal seam thickness of working face inner was studied by 3D forwardsimulation, it proved coal seam thickness variation could be detected by transmission channel wave , finally, the coal seamthickness of one coal mine of Huangling was detected by transmission channel wave technology, then coal seam thickness variation ofworking face was ascertained. The results showed that coal seam thickness of working face inner could be detected by transmission channelwave technology effectively, it provide effective technical support for mine safety mining.
