摘要
为探测掘进前方隐伏的含水构造,预防地质水害,解决煤巷综掘过程中日益突出的"探、掘"矛盾,论文提出和研究电场约束法煤巷综掘探测方法.该方法利用电场同性相斥的原理,使发射电场被约束在一定范围内,达到定方向定距离探测的目的.根据该方法基本原理,建立超前探测有限元仿真模型,开展相应的数值模拟.论文主要从探测基本方法,激发极化程度、异常体的体积大小及巷道内金属体对于超前探测的影响展开模拟研究.结果表明,该方法可以有效探知掘进面前方的含水地质异常,其探测有效距离约为10m.该研究为电场约束法煤巷综掘超前探测方法的实现奠定了理论基础,对综掘超前探测技术的发展具有重要的推动作用.
To effectively detect the concealed water-bearing geological structure in front of the tunneling and prevent the geological disasters, to solve the increasingly prominent contradiction between detection and tunneling in the process of coal roadway comprehensive tunneling,this paper put forward and researched the advanced detection method based on the electric field constraint method.This method uses the principle of the same electric field repelling each other and makes the launch electric field restrained in a certain range to achieve the goal of the detection whose direction and distance is determined.According to the basic principles of the method,the finite element simulation model of advanced detection was established and the corresponding numerical simulation was carried out.The thesis mainly simulated the basic detection method and the influence of the degree of induced polarization,abnormal body size and the metallic anomalies existing in the roadway on the advanced detection.The results indicated that this method can effectively detect the water-bearing geological abnormal body and the detection range is about 10 m.The research lays a theoretical foundation for the achievement of the advanced detection of comprehensive tunneling in coal roadway based on the electric field constraint method and will play an important role for the development of comprehensive tunneling advanced detection technology.
