基于SH槽波的煤矿超前探测技术研究

Research on advanced detection technology of coal mine based on SH wave

为了确保工作面合理煤柱的留设以及矿井的安全生产,采用SH槽波超前勘探方法,对某矿煤层进行了超前探测,探测使用爆破震源的方式,利用反射法进行探测。探测结果表明:该矿煤层具有良好的槽导性与波导特性,采用SH槽波超前勘探是可行的;该矿已经揭露的3个断层为同一个断层,并且已经延伸到下一备采工作面,应该加大煤柱的留设,研究结果对类似工程地质条件超前探测有借鉴意义。

In order to ensure the reasonable design of coal pillar and the coal mine safety production, using the SH slot wave in tunnel exploration method, coal seam of a coal mine advanced detection, by the use of blasting source in detection, detection using reflection method. The results show that：the coal mine has good guide slot waveguide,using SH slot wave in tunnel exploration is feasible;3 faults have been exposed in this coal mine which proved to be the same fault, and has been extended to the preparation working face, it is nec-essary to increase the stay of coal pillars, which provides a reference for the similar research results of engineering geological conditions advanced detection.
