摘　　要：云驾岭矿区地质条件较复杂,为了正确指导工作面的设计、掘进和回采,减少因地质构造不清造成煤炭资源浪费和废巷工程,需查明工作面内隐伏地质构造。针对这一问题,在云驾岭矿区进行地震CT探测研究,并在2个工作面震波CT成像分析试验研究的基础之上,采用数值模型模拟、室内物理模拟实验等方法对矿区煤系地层的弹性属性参数、地质构造进行分析、研究、验证,总结出适合矿区地质条件的地震CT波速度参数和有效的解释方法。经5个工作面的开采验证结果表明,工作面震波CT探测方法和选用的参数科学合理,探测成果可靠。The geological conditions in Yunjialing mining area were relatively complex. In order to correctly guide the design, advancing and recovery mining of working face and reduce the coal resource waste and roadway engineering caused by unclear geological structure, based on this problem, seismic CT detection research was carried out in the Yunjialing mining area, and on the basis of two working face seismic CT imaging analysis experiments, numerical model simulation,indoor physical simulation experiments and other methods were applied to study the coal-bearing strata of the mining area.The elastic attribute parameters and geological structure were analyzed, studied and verified, and the seismic CT wave velocity parameters and effective interpretation methods suitable for the geological conditions of the mining area were summarized. The results of mining verification of 5 working faces showed that the CT detection method and selected parameters of the working surface were scientific and reasonable, and the detection results were reliable.
