层状空间矿井直流电法超前探测曲线特征研究
|
摘要
为研究井下不同地层条件下的矿井直流电法超前探测视电阻率曲线响应特征,建立了全空间水平3层和5层介质模型,对巷道所在层及巷道上覆岩层的厚度、电阻率等因素变化对超前探测的影响进行了数值模拟。通过对比分析,形成了一些关于超前探测方面的新认识,这些认识对于超前探测的数据采集以及资料解释有实际应用价值。
In order to study the response characteristics of apparent resistivity curve of mine DC electric detection in advance under different strata conditions in underground mine, the three-layer and five-layer medium model of full space level was established to study the influence factors of advanced detection included thickness and resistivity of the same floor and the overlying strata in the roadway.These influence factors are numerically simulated. Through comparative analysis, some new understandings about advanced detection are formed, which have practical application value for data acquisition and data interpretation of advanced detection.
