摘要

    摘要
  • 摘要: 矿井直流电法超前探测效果影响因素较多，为讨论井下不同因素对地下全空间电流场分布的影响，运用Ansoft Maxwell有限元软件，分别建立均匀介质、巷道开挖及低阻异常层状模型进行正演模拟。结果表明：受巷道开挖影响，全空间电场由同心环状分布变为螺旋状分布，且受巷道空腔影响，巷道顶板电场强度、电流密度明显小于底板，靠迎头一侧电流、电流密度在迎头附近出现跳跃增大，呈现电流集中现象。由于地电断面的存在，电场强度和电流密度在分界面处均发生折射现象。受低阻体的"吸引"作用，低阻体内部电流沿其走向流动，电场强度降低而电流密度升高；低阻体外部电场强度升高，电流密度降低；并在异常体边角处出现明显的电流集中现象。受此影响，整个区域视电阻率均有所下降。与理想状态等电位相比，由于巷道及异常体的存在，电场强度和电流密度差值等位线略有畸变，导致掘进迎头前、后等电位面距供电电极并不完全相等，掘进迎头前方小于后方。在实际运用直流电法进行巷道超前探测时，应综合考虑顶底板岩性、厚度及低阻体电阻率、规模及与迎头距离等诸因素对低阻体实际位置的影响。
    Abstract: The advanced DC electric detection is affected by many factors, which mainly affect the distribution of the whole current fields. The Ansoft Maxwell software was used to build up three models (the uniform medium model, tunnel excavation model and low resistivity layer model). The forward simulation showed that the current field distribution changed from concentric circle into spiral because of the tunnel excavation, the roof current intensity and current density were significantly less than the floor, and the current intensity and current density were concentrated near the heading face. Because of the geoelectric section, the current intensity and current density were refraction on the interface. By attraction of the low resistance bodies, the current intensity decreased and the current density increased in low resistance bodies, and current flowed along the bodies. On the contrary, the current intensity increased and the current density decreased outside of low resistance bodies, and the current field was concentrated on the corners. Affected by those, the whole apparent resistivity was decreased.
