基于无线电磁波透视工作面煤层情况探测

采用无线电磁波坑道透视和瞬变电磁探测技术对四侯煤业3101首采工作面的煤层厚度、构造异常和富水性等进行了探测,并从井下掘进实际揭露工作面煤层情况对探测结果进行了验证,结果表明：3101首采工作面存在3个断层或煤层变薄影响区,沿煤层走向影响范围分别为100 m、100 m和170 m,这三个断层或影响区域对工作面的采煤方法和采煤工艺选择具有积极的指导意义。

Coal Seam Prospecting Based on the Perspective of Working Face with Radio Electromagnetic Wave

The thickness of coal seam, structural abnormalities and water yield property of 3101 first-mining face of Sihou Coal Industry were prospected with radio electromagnetic wave tunnel perspective and transient electromagnetic detection technology, and the prospecting results were verified by the actual situation of coal seams in revealed mining face of underground excavation. The results showed that there were three faults or seams thinning affected zone in 3101 first-mining face, and the affected ranges along the seam were 100 m, 100 m and 170 m, which have positive guiding significance to the selection of coal mining methods and processes.
