Through the lab flume (1.2m long and 0.85 deep) experiment and a high-resistivity rock (approximately 1000Ωm) under the low-resistivity salt water (approximately 3Ωm) background, this paper carries out inversion with cross-hole, borehole-to-surface and surface-to-borehole arrays. The inverted maps from the cross-hole and borehole-to-surface data cannot perform the target well but it can roughly delineate the boundary between the high-resistivity and low-resistivity layers. The inversion resolution of the surface-to-borehole data is the worst of the three types. However, the joint data set can increase the inversion resolution without the poor-quality data set being added into the inversion calculation. ERT investigation with borehole-to-surface array was employed in Chifeng in the northeast of Inner Mongolia, China. A smallscale was delineated with high-resolution, which is consistent with the drilling data.}, number={12}, journal={Journal of Mines, Metals and Fuels}, author={Jia, Zheng-Yuan and Zhang, Gang and Zhang, Gui-Bin}, year={2017}, month={Dec.}, pages={634–640} }
