【摘要】：為保證紅慶梁煤礦回風(fēng)巷道斷層地質(zhì)條件下的回采工作面安全,同時實現(xiàn)高效回采的目的.采用KDZ1114-3便攜式礦井地質(zhì)探測儀,結(jié)合反射共偏移法原理對回風(fēng)大巷斷層情況進(jìn)行預(yù)報.在利用便攜式礦井地質(zhì)探測儀對巷道斷層的探測之后,對采集到的波形進(jìn)行后期處理分析.研究結(jié)果表明:斷層破碎帶及發(fā)育區(qū)在迎頭約0~15 m,推測斷層位于迎頭前方3~7 m處,另外位于迎頭前方15~20 m處存在另一小斷層或者巖性變化.通過分析結(jié)果同實際開挖情況對比可知,分析結(jié)果比較準(zhǔn)確.
[Abstract]:In order to ensure the safety of mining face under the condition of fault geology of return air roadway in Hongqingliang coal mine, and realize the purpose of high efficiency mining at the same time. KDZ1114-3 portable mine geological detector is used to predict faults in return air roadway combined with the principle of reflection co-migration. After using portable mine geological detector to detect the fault of roadway, the acquired waveforms are processed and analyzed. The results show that the fault fracture zone and the developed zone are about 0 ~ 15 m in headhead. It is assumed that there is another small fault or lithologic change in the fault zone at 3 ~ 7 m in front of head and 1520 m in front of head. By comparing the analysis results with the actual excavation conditions, we can see that the analysis results are more accurate.
