回采工作面透射多波探测技术在霄云煤矿中的应用

Application of transmitted multi-wave exploration in working face of Xiaoyun Coal Mine

回采工作面内断层、冲刷带等隐蔽灾害因素是影响煤矿安全生产的重要隐患之一;利用透射多波探测技术快速、无损、对地质构造反应灵敏的特点,对回采工作面未知地质构造进行了探测;参考巷道实揭地质资料,联合利用了体波及槽波反演结果,综合超前预报回采工作面断层及煤层变薄带范围,为回采工作面布置提供设计依据,保证了煤矿安全高效生产。

Fault and erosion zone in coal mining face are important hazards which effect the safety of coal mine.Transmitted multi-wave exploration was used to detect the unknown geological structure,because of its characteristic of celerity,non-destructive and responsive to geological structure.According to geological data of roadway,and the results of body wave and channel wave were used,fault and coal seam thinning zone in working face were advanced predicted.The detected results of transmitted multi-wave exploration may provide the design basis for the layout of the coal mining face,and ensure the safe and efficient production of coal mine.
