红庆梁煤矿巷道断层带的超前地质预报

Advanced geological prediction of the fault zone in the coal mine roadway of the Hongqingliang

为保证红庆梁煤矿回风巷道断层地质条件下的回采工作面安全,同时实现高效回采的目的.采用KDZ1114-3便携式矿井地质探测仪,结合反射共偏移法原理对回风大巷断层情况进行预报.在利用便携式矿井地质探测仪对巷道断层的探测之后,对采集到的波形进行后期处理分析.研究结果表明:断层破碎带及发育区在迎头约0~15 m,推测断层位于迎头前方3~7 m处,另外位于迎头前方15~20 m处存在另一小断层或者岩性变化.通过分析结果同实际开挖情况对比可知,分析结果比较准确.

In order to ensure the safety of Hong Qing Liang working face return roadway under the geological conditions of coal mine fault beam, and achieve the purpose of efficient mining, this paper used the KDZ1114-3 portable mine geology detector, forecasted the air return laneway fault with the reflection offset method principle, After using the portable mine detector to detect the fault of roadway, the post processing analysis of the collected waveforms was carried out. The results of study show that fault fracture zone and development zone in head-on is about 0-15 m, and the fault is located in the head-on in front of 3-7 m; also another small fault or lithological change is located in head-on 15-20 m ahead. Through comparing the analysis of the results with the actual excavation of the situation, the analysis results are more accurate.
