Devolopment of Software to Evaluate Roof Fall Risk in Bord and Pillar Method -Depillaring Phase

Abstract

Roof fall is one of the biggest problems of the bord and pillar coal mines during depillaring phase. Roof fall not only causes great damage to the mining equipment but also to the miners. It is clear that development of software is essential for calculation of roof fall risk in bord and pillar coal mines depillaring phase in order to reduce the accidents. Software has been developed and tested on two coal mines - seam 2, main panel of RK-5 and seam 2, main panel of RK-6 underground coal mine, SCCL India. Corresponding roof fall risk was calculated and the best combination of the parameters causing roof fall risk was evaluated to reduce the risk
