井下综合超前探测技术应用与分析研究

针对煤矿水害事故的频繁发生，煤层顶底板及前方水体灾害探测不准确不及时的难题，根据“预测预报、有掘必探、先探后掘、先治后采”原则，提出了将地震槽波勘探、瞬变电磁法和无线电波坑透3种物探方法相结合，对每种物探方法的异常区域相互联合解释，对异常重叠区域进行重点防治。从探测成果图看，槽波地震勘探分辨率高，对于煤层厚度以及细小构造探测效果好；无线电波透视法对顶底板水体灾害反应灵敏，瞬变电磁对于低阻富水灾害体灵敏度高，3种方法的异常重叠区域就是比较可靠的富水区。结果表明:采用多种方法进行综合勘探，异常定位准确可靠，能够发挥每种方法的优越性，为煤矿井下超前探测提供了新的思路。

Application and analysis of underground comprehensive advance detection technology

In view of the frequent occurrence of coal mine water hazard accidents，the problem of inaccurate and untimely detection of coal seam top and bottom water and front water bodies is based on the principle of “predictive forecasting，excavation，exploration，excavation and treatment”.Wave exploration，transient electromagnetic method and radio wave tunneling were combined with three geophysical methods.The anomalous areas of each geophysical method were explained jointly and the key overlapping areas were controlled.From the detection results map，the trough wave seismic exploration had high resolution，and the detection effect on coal seam thickness and fine structure was good；the radio wave perspective method was sensitive to the water disaster of the top and bottom plates，and the transient electromagnetic was sensitive to the low-resistance water-rich disaster，the abnormal overlap area of the three methods was a relatively reliable water-rich area.The results showed that:using a variety of methods for comprehensive exploration，the anomaly positioning was accurate and reliable，can play the superiority of each method，and provided a new idea for coal mine underground advanced detection.
