Coal mining solid filling three-dimensional simulation platform

The present invention discloses a coal mine backfill mining solid three-dimensional simulation platform that can study the effect of backfill mining Coal mining solid filling. The platform includes an internal analog laying seam of the box, the box provided at the top of the roof load loading means disposed in the housing interior of coal mining equipment and backfill compaction bodies, as well as backfill grouting system, and signal acquisition system The data processing system. The experimental platform to test different filling materials ratio, different filling technology, deformation characteristics under different conditions of coal seam filling material and overburden movement law in the laboratory to achieve a similar simulation experiments solid backfill mining effects, It is a reliable, economical and simple experimental means.
