射电定位法在煤矿老空水探测中的应用

射电辐射探测地下水是新的方法，而利用单台射电辐射计对煤矿老空水进行探测并确定其位置是生产实践中更新的技术。使用单台矿用射电水探测仪，用射电定位法在井下对煤矿老空水进行探测定位，通过数据处理、射电折射修正，成功实现了煤矿老空水位置的准确定位。经徐州三河尖煤矿钻孔验证，射电折射修正后的射电定位数据与实际钻孔数据相比，钻孔深度误差约为1 m，钻孔角度误差约为1.1°，与煤矿井下探测老空水位置的其他方法比较，上述2个误差最小。

Application of radio positioning method to the detection of mine goaf water

Radio radiation detection is a new topic of groundwater, and the use of a single radio radiometer to detect coal mine goaf water and to determine its position is an updated subject in production practice. This work described the use of a single YST 13.2 mine radio water detector for goaf water of coal mine detection and basic principle, testing method, data processing, radio refraction correction and drilling validation process. This is the first time that we have used the radio-ray location method to detect mine water in the. Drillingverification of the Sanhejian coal mine indicates that the error of drilling depth is 1m and the error of drilling angle is 1.1° by comparing radio positioning data after radio refraction correction with the actual drilling data. Compared with other methods of detecting goaf water in underground coal mine, the above two errors are the smallest
