无线电波透视CT探测技术在薛虎沟矿2-105工作面的应用

Application of Radio Wave Perspective CT Detection Technology in 2-105 Working Face of Xuehugou Mine

薛虎沟矿为探明2-105工作面内煤层赋存及隐伏构造情况,保证工作面的回采安全,采用无线电波透视法对工作面构造进行探测。结合工作面的实际情况,采用频率460.8 k Hz的探测仪器,发射点采用定点交汇法布置。探测结果分析表明:工作面300~365 m范围内存在部分煤层变薄区,坑道透视异常区域与巷道煤层变薄区域基本相符。

In order to find out the occurrence and hidden structure of coal seam in 2-105 working face in Xuehugou mine,the radio wave perspective method is used to detect the structure of working face.Combined with the actual situation of the working face,the detection instrument with frequency of 460.8 k Hz is adopted,and the emission point is arranged by fixed-point intersection method.The analysis of detection results shows that there are some coal seam thinning areas within 300~365 m of working face,and the abnormal area of tunnel perspective is basically consistent with the thinning area of coal seam in roadway.
