Grouting simulation experiment device and method for monitoring slurry diffusion range in real time

The invention relates to a coal rock mining simulation technology. An existing experimental device adopts a transparent plate or a method of splitting a test piece after a test to determine the diffusion range of slurry, the diffusion range of internal slurry is not easy to determine by the transparent plate, transparent particles have great influence on the effectiveness of a grouting simulationexperiment, and the test piece splitting has a damage risk. The invention provides a grouting simulation experiment device and method for monitoring the slurry diffusion range in real time, a groutingbarrel is communicated with a test box, a plurality of insulating wiring nets are arranged in the test box, and a plurality of negative electrode electric sheets connected with a grouting test operation table are uniformly distributed on the wiring nets; in the grouting process, the slurry diffusion range is determined according to the position of the conducted negative electrode electric sheet and the conduction time, re
