Effect of Compressive Behaviours of Tail Salt Filling Materials on Roof Deformation in Potash Mine

To resolve the problem of top mine instability and the consequent ecological damage caused by different grades of ore deposits in the layered mining process, layered filling-pillar-mining-displacement method (LFPMD) is proposed using a potash mine as an example. Based on the operation principles of...
