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 mining working face under the fault geological conditions of return airway in Hongqingliang coal mine and realize the purpose of high efficiency recovery at the same time, KDZ1114-3 portable mine geologic detector was used in combination with the principle of reflection co-offset method to analyze the fault condition After the detection of roadway fault using portable mine geologic detector, the collected waveforms were processed post-processing.The results show that the fault fracture zone and the development zone are about 0 ~ 15 m in height, and the fault is located in front of the head-on 3 ~ 7 m, and another small fault or lithologic change exists 15 ~ 20 m in front of the head.According to the comparison between the analysis result and the actual excavation, the analysis result is more accurate.
