文章以煤矿掘进巷道地质含水情况为研究对象,通过含水结构分析建立了能够反映真实巷道水文情况的物理模型。利用水含量变化会引起介质视电阻率变化这一原理,建立物理模型的等效激电模型,通过计算机仿真技术对地质构造激电模型进行结果计算并分析,得出了高低频视电阻率变化曲线和PFE变化曲线。计算机仿真结果能够有效的反映真实掘进巷道前方地质结构,为掘进工作的超前预测提供了有效的科学依据,也为今后的超前探测仪器的开发提供了一定的思路。
Taking the geological water content of tunneling roadway as the research object, the article establishes a physical model that can reflect the hydrological conditions of the real roadway through the analysis of water-bearing structure. Based on the principle that the change of apparent resistivity of the medium can be caused by the change of water content, an equivalent model of the physical model is established, and the results of calculation and analysis of the geoelectric tectonic model are calculated by computer simulation. Curve and PFE curve. Computer simulation results can effectively reflect the geological structure in front of roadway and provide an effective scientific basis for the advanced prediction of roadheading and provide some ideas for the development of advanced detection instruments in the future.
