摘　　要：断层构造是影响矿井采掘衔接和安全生产的重要因素之一,为了提前查明断层的赋存特征,避免回采和掘进过程中无计划揭露断层构造带来的人员伤亡和财产损失,选择赵庄二矿2301工作面为试验现场,展开槽波地震反射法勘探,通过探采结果对比,研究了该方法对断层构造精确探查的有效性。研究结果表明:以探测区域870 m/s的槽波速度进行分析和计算,槽波反射法探测出采面内存在一走向为南西向,延伸长度约207 m的反射界面,震相十分清晰,推断为断层构造,经过巷道掘进和工作面回采揭露,有效验证了该断层的存在,且走向近乎一致,位置偏差不大于10 m,因此,槽波地震反射法勘探对断层构造的探测效果良好,能够有效指导矿井的安全生产。The fault tectonic is one of the important factors affected to the mine mining and heading connection and the mine safety production. In order to ascertain deposition features of fault and avoid personnel casualty and property loss occurred form fault tectonic exposed without any preparation during the mining and heading process,No. 2301 coal mining face in Zhaozhuang No. 2 Mine was selected as the experiment site and explorations with the channel wave seismic reflection method were conducted. With the comparison between of exploration and mining results,the paper had a study on the efficiency of method to curate exploration of fault tectonic. The study results showed that an analysis and calculation were conducted with channel wave velocity of 870 m/s in detection area,a reflecting interface with a southwest strike and a extend length about 207 m existed in coal mining face were detected with the channel wave reflection method. The seismic phase was very clear and a fault tectonic was inferred. The exposed mine roadway heading and the coal face mining effectively verified the fault existed,the strike was nearly the same and location error was not over 10 m. Therefore,the exploration with the channel wave seismic reflection method could have a good detection effect to the fault tectonic and could effectively guide the mine safety production.
