摘要
针对煤矿井下的安全、高效的开采,传统的瞬变电磁探测系统存在着较大的探测盲区和探测精度不高,无法对煤矿井下水体的精确定位等问题;考虑矿井巷道的具体的施工环境和空间的限制,开发了多通道瞬变电磁采集系统;该系统使用高精度小线圈进行阵列式探测,使用多通道采集技术进行同步采集。在同煤集团塔山煤矿进行了超前探测实验,实验结果表明：多通道阵列式采集系统相对于传统的接收线圈,多通道采集系统不仅达到了传统线圈的探测效果,而且减小了探测盲区,在干扰较强的巷道,具有较好的探测效果。
In this paper, in order to achieve safe and efficient mining of the coal mine, the traditional system of transient electro- magnetic method （TEM） has the problem of large detection blind area and low detection accuracy, so multi-channel system of TEM is developed. The system uses high precision and small coil array to detect, uses multi-channel sampling technology to carry out synchronous collection. By the experiment of advanced detection in Datong Coal Mine Group, the measured results show that using multi-channel system of TEM can instead of traditional TEM system, and the multi-channel system of TEM can decrease the detection blind area. Under strong interference of roadway, the multi-channel system of TEM has good detection effect, which has widely potential application in the advanced detection of coal mine.
