Strata pressure behavior and overlying strata movement characteristics of slicing backfill mining in thick coal seams
To improve the coal recovery rate, paste backfill mining was used for 3# coal seam under the industrial square in Panji No.4 Coal Mine. Theoretical analysis, numerical simulation, and similar simulation were applied to study the underground pressure behavior and the overlying strata movement. Result...
