摘要
综掘巷道掘进速度相较更快,若出现误揭未掌握隐伏构造、富水区等,则容易出现围岩变形严重、涌水量大等问题。为此,针对山西A矿水文地质条件复杂情况,提出将瞬变电磁法、直流电法应用于2301运输顺槽超前探测中,将瞬变电磁法、瑞利波法应用于7501回风顺槽超前探测中。结果表明,采用的综合物探技术应用效果显著,可实现2301运输顺槽、7501回风顺槽掘进区域隐伏构造及富水区超前探测,探测结果可为巷道掘进及防治水开展提供指导。
The excavation speed of fully mechanized excavation tunnels is relatively faster.If there are errors in uncovering hidden structures,rich water areas,etc.,it is easy to cause serious deformation of surrounding rock and large water inflow.Therefore,in response to the complex hydrogeological conditions of Shanxi A Mine,it was proposed to apply transient electromagnetic method and direct-current method to the advanced detection of 2301 transportation channel,and transient electromagnetic method and Rayleigh wave method to the advanced detection of 7501 return air channel.The results show that the comprehensive geophysical exploration technology used has significant effects,and can achieve advanced detection of hidden structures and rich water areas in the 2301 transportation channel and 7501 return air channel excavation areas.The detection results can provide guidance for tunnel excavation and water prevention and control.
