摘要
为保证九里山矿井的安全生产,在14141工作面实施了坑透技术实验进行构造预测。通过分析工作面实际情况及井下探测频率实验,确定了坑透电磁波频率和测点布置方案。通过对比电磁波衰减系数层析成像与运输底抽巷实揭资料表明:实验进展顺利,数据可靠;无线电坑透探测结果与地质实际吻合性较好,精确度较高;坑透技术在煤矿生产中具有良好的应用效果。
In order to ensure safe production of coal mine,structures were predicted by the pit prospecting experiment in14141 working face of Jiulishan Coal Mine. Based on the actual situation of the working face and the electromagnetic wave frequency experiment for detection in the pit, the frequency of the electromagnetic wave and the arrangement of the measuring points were determined. The experiment was progressing smoothly,and the data was reliable. It was proved that the detection results agreed with geological reality through contrasting the tomography with the geological data of transportation roadway. The pit penetration technology achieved a good application effect in coal mine production.
