摘要
针对厚煤层条件下综采工作面回采过程中可能会遇到的地质构造和查明工作面一定范围内煤层底板岩层的含水情况,确保工作面回采的安全性,通过运用无线电波坑道透视和井下瞬变电磁技术等综合物探方法,对可能遇到的地质构造和含水异常区域进行探测,进而分析和论证回采的安全性,为煤矿的安全生产提供技术依据。
Based on the geology structure and water-bearing of coal seam floor stratum in fully mechanized working face recovery under thick coal seam, in order to ensure the safety of working face recovery, radio wave tunnel perspective and underground transient electromagnetic method were used to detect the geology structure and abnormal water-bearing area,the safety of recovery mining was analyzed and demonstrated, which provided technical reference for safe mining.
