Development of Computational Software to Determine the ‘Factor of Safety’ of Bord and Pillar Working as Per Tributary Area Approach

Abstract

Factor of safety (FOS) plays an important role in mine planning. Various factors/parameters are necessary to determine the FOS by tributary area approach especially in bord and pillar working. Investigations have been carried out to determine the parameters affecting the selection of bord and pillar method in underground coal mines. The data are entered according to the Indian mining conditions and requirements to exhibit the planning of a mine to determine the best fit result. This dissertation emphasises on to develop a software for the mine planners and administration to take ameliorative measures in advance to design a stable bord and pillar working based on relation between pillar dimensions and FOS
