[ 1 ] - Comparing the “Modified Split and Fender” and “Shortwall” Methods for the Pillar Recovery in Room and Pillar Coal Mining Using A 3D Finite Difference Modeling in Tabas Central Coal Mine, Iran

Selecting a suitable pillar recovery method is one of the most important issues in the room and pillar mining. The main purpose of this study is to compare two methods for pillar recovery in Tabas central coal mine (TCM). Among the existing methods, the two methods, “Modified split and fender” and “Shortwall” are chosen for the numerical modeling. The three dimensional finite difference method ...
