摘要
矿井水害严重影响福建煤矿的正常安全生产,其超前预测预报已成为重大安全技术难题之一。为查明福建小井尖煤矿掘进巷道顶底板及前方含水异常体的空间位置及分布范围,运用矿井瞬变电磁法探测技术对其+620水平东运巷掘进巷道前方、顶底板含(富)水性进行超前探测。结果表明:该矿+620水平东运巷道掘进迎头前方80m范围、顶底板上下各50m范围内总体含水性弱,但迎头前方40~45m范围确定为局部含水区,富水性较弱,与后期掘进及工程钻探跟踪对比、验证结果吻合,探测成果为保障该矿巷道安全掘进提供了技术支撑。
Mine water disaster seriously affects the normal and safe production of coal mines in Fujian province, and its advanced prediction has become one of the major safety technology problems. In order to find out the spatial location and distribution range of abnormal water-bearing body in the roof and floor, as well as the front of drivage roadway in Xiaojingjian coal mine of Fujian province, the mine transient electromagnetic method technology was applied to in advance detect the aquosity or water a-bundance in the front, roof and floor of the drivage roadway in the east transportation lane of the ＋620 level. The results showed that the aquosity was weak overall at the 80 m range in front of tunneling head, as well as at the upper and lower 50 m range of the roof and floor in the east transportation lane. But at the 40~45 m range in front of tunneling head was identified as local aquifer with weak water abundance, which was consistent with the results of tracking comparison and verification of the later tunneling and engineering drilling. The detection results could provide a technical support to guarantee safe tunneling for this mine.
