摘要
Through the establishment of the model for groundwater seepage-electric test,mine roof water-inrush was simulated and coarse-grained sand,medium-grained sand and fine-grained sand were partly used as aquifer media.The properties of transient response of parameters of the geoelectric field are real time monitored by network parallel electrical equipment.The apparent resistivity section diagram can clearly show the change process at seepage,water-inrush and post-water-inrush stages,which can be applied to judge the water capacity of aquifer.
