摘　　要：为了有效指导井下煤炭开采工作,采用槽波勘探技术对煤矿进行超前勘探,以某矿2111工作面为例,研究了槽波的形成机理与勘探方法,利用透射法—反射联合法,对2111工作面进行煤层地质勘探。研究结果得出:在探测区域内,每个检波点都接收到了明显的槽波信号,勘探区域整体地质构造较为简单;研究区域有4个明显的高速异常区,与实际揭露地质构造进行对比分析,探测结果与实际揭露的地质构造相吻合,验证了槽波勘探技术的准确性,并在研究区右下角发现有另一断层存在,在进行掘进时,应当提前采取安全过断层措施,确保煤矿安全生产。In order to effectively guide the underground coal mining work,the trench wave exploration technology was used to carry out the advance exploration to the coal mine. Taking 2111 working face of a mine as an example,the forming mechanism and exploration method of the trough wave were studied,and geological exploration of coal seam was carried out on 2111 working face,the results showed that： in the detection area,each detection point has received a clear trough wave signal,the exploration area of the overall geological structure is relatively simple; study area has four obvious high-speed anomaly areas,and the actual disclosure results of geological structure for the investigation were consistent with the geological structure exposed,and the accuracy of the trench wave exploration technology was verified. Another fault exists in the lower right corner of the study area. When the tunneling is being drived,the safety passing-through fault measures should be carried out in advance to ensure the safety of coal production.
