摘要
为了解决巷道掘进施工时超前钻探钻孔盲目布置、钻孔有效性低的问题,应用隧道地震波反射层析成像技术(TRT)和地质雷达超前地质预报技术(GPR)对某矿正在掘进的巷道进行超前预报,根据探测结果分析得到的掘进面前方不良地质体的发育位置设计了超前钻探施钻方案。将预报结果、钻探结果以及开挖情况进行对比得到:采用的联合预报技术比较准确地预报了含水异常体的发育位置;根据联合地质预报的成果可以有效指导巷道掘进过程中的水平钻施钻的位置和数量,有效缩短施工工期、降低了钻探费用。将联合预报结果与钻探情况以及开挖情况进行对比分析,说明TRT和GPR联合探测技术可以有效指导超前钻探施钻。
In order to solve the problem of blind placement of drilling holes and low drilling effectiveness during roadway excavation construction.The tunnel seismic wave reflection tomography(TRT)and geological radar advanced geological prediction technology(GPR)were used to predict the roadway of a mine that was being excavated,based on the analysis of the detection results,the development position of the unfavorable geological body in front of the excavation was designed as an advanced drilling plan.By comparing the forecast results,drilling results,and excavation conditions,it could be concluded that the joint forecasting technique used to accurately predict the developmental position of aqueous abnormal bodies.According to the results of joint geological prediction,the position and quantity of horizontal drilling and drilling in the roadway excavation process could be effectively guided,effectively shortening the construction period and reducing the drilling cost.The joint forecasting results were compared and analyzed,and the joint detection of TRT and GPR could effectively guide the advance drilling and drilling.
