摘　　要：针对煤矿开采工作中诱灾水体变化容易导致矿井工作环境坍塌的问题。研究利用含水缝隙的电性特征和电阻率层析成像的装置来模拟突水过程,并设计出矿井水害信息长时监测系统,进而检测含水缝隙的低阻区域的电流场变化。在水槽模拟矿井的仿真实验中,矿井电极在40、80、120 m附近的反演成像结果与模拟试验基本相同,并在矿井深度达到43 m以下时出现高阻趋向。结果证明了仪器和软件控制监测系统的稳定性和准确性,并为矿井水害信息的预警提供理论基础技术参考。Due to the impact of water inrush in coal mining work on mine safety,the early warning design and research of disaster inducing water bodies have received great attention.Research the use of resistivity tomography to simulate the process of water inrush,and then design a long term monitoring system for mine water damage information to conduct experiments on low resistance areas of water containing cracks.Then,a water tank simulation experiment was conducted to verify in the field that the inversion imaging results of the electrodes near 40 m,80 m,and 120 m were basically the same as the simulation experiment,and a high resistance trend appeared when the mine depth reached below 43 m.The results demonstrate the stability and accuracy of the instrument and software control monitoring system,and provide theoretical and technical references for early warning of mine water damage information.
