During mine filling, the caking in pipeline and waste rock filling slurry may cause serious safety accidents such as pipe blocking or explosion. Therefore, visualization of inner solid–liquid two-phase flow is important. This paper proposes a method based on capacitance tomography for distribution section pipe. A feedback network used electrical reconstruction. reconstruction uses radial basis function neural fitting to determine relationship between vector medium error. In process, error linear back projection removed; thus, problem becomes an accurate problem. The simulation results show that accuracy this algorithm better than many traditional algorithms; furthermore, reconstructed image artifacts are fewer, phase boundary clearer. can help location size cross more accurately has great application prospects pipelines mines.
