基于ANSYS的采动围岩视电阻率动态变化模拟

摘要

Setting deformation theory of top and bottom layers caused by coal mining and rock and ore conductive factors as the basis, on the basis of the damage distribution, the roof and floor coal strata can be divided into many electrical sections, and geoelectric model can be established. Using ANSYS software for finite element analysis, through apparent resistivity contour map, apparent resistivity changing regularity caused by coal mining has been summarized and analyzed. Through analysis on the apparent resistivity change situation, a series of problems existed in coal mining can be solved. It will guide safe and high efficiency production in coal mine.%以煤层开采引起的顶底板岩层变形破坏理论及岩、矿石导电性的影响因素为理论依据，在顶底板岩层破坏分布范围的基础上，可以将煤层顶底板分别划分为若干个电性区段并建立地电模型。利用ANSYS软件进行有限元分析，通过视电阻率等值线图总结分析煤层开采引起的视电阻率变化规律，对视电阻率的变化状况进行分析，可以解决一系列的矿井地质问题，从而能够指导煤矿安全高效的生产。
