为保障巷道掘进过程中的安全性,以山西焦煤霍州煤电洪崖煤业有限公司 3-1021 运输巷道为研究对象,采用理论分析和现场实测的方法对综合物探法在掘进工作面的应用展开研究.研究结果表明:3-1021 巷道在同层隐伏构造及上覆小窑破坏区可能存在水患威胁;以直流电法和瞬变电磁法相结合的综合物探法用于巷道掘进工作面的超前探测,可有效增加掘进工作面超前探测的精度;依据综合物探法的探测结果,3-1021 巷道掘进过程中共对 4 处水害威胁区域进行了钻孔放水作业,保障了巷道掘进工作面的安全.
In order to ensure the safety in roadway excavation in 3-1021 haulage roadway of Hongya Coal Industry Co.,Ltd.,the author probes into the application of comprehensive geophysical prospecting method in the driving face by theoretical analysis and field measurement,whose research results show that 3-1021 roadway may be threatened by flood in the hidden structure of the same layer and the destruction area of the overlying small kiln;the comprehensive geophysical prospecting method combined with the direct current method and the transient electromagnetic method can effectively increase the accuracy of the advanced detection of the driving face;a total of 4 water hazard zone were drilled and drained during the excavation,ensuring the safety of the roadway excavation face.
