矿井直流电法超前探测是地球物理勘探技术中的重要手段之一。该文介绍了矿井直流电法超前探测的基本原理、工作方法及数据的处理流程。通过数值模拟和物理模拟实验,说明其工作的基本步骤和预报结果并以淮南潘北矿东翼A组煤矿放水大巷掘进超前探测为例,分析了矿井直流电法在探测巷道前方岩层富水区中的效果,表明了直流电法超前探测技术在实际应用中的可行性、实用性,具有较理想的效果。
Mine DC method ahead of the probe is one of the important means of geophysical exploration technology. This paper introduces the basic principles, working methods and data processing flow of mine direct current method advanced detection. Through numerical simulation and physical simulation experiments, the basic steps and forecasting results of its work are described. Taking advanced detection of group A coal mine drainage tunnel in the east wing of Huainan Panbei Mine as an example, the paper analyzes the method of mine direct current method In the results show that the DC method advanced detection technology in practical application of feasibility and practicality, with the desired effect.
