Abstract

It is impossible for this industry, which makes a major contribution to the mining sector, to continue to exist unless new technology is developed to make mining economically feasible. This article describes the findings of a study conducted for a complete mining system in PT. X. Main objective of this study was to determine the optimal Pillar and Roof parameters for new mining technique with continuous miner, which was accomplished via simulation. The characteristics of the room and pillar mining systems were determined using the calculation formula and conditional thickness techniques, which ensured that the system would be stable over the long run. The techniques of computation that were employed produced outstanding results. The most significant of these techniques is the increase in coal output via continuous mining, although it is essential to keep an eye on the stability. The influence of the random variation of the actual room sizes on the stability of the immediate and main roofs is minimal and is not taken into account in the calculations of immediate and major roof stability. The results of the investigation revealed that the safety factor for the estimated room size of 8 and 10 m is insufficient. According to the geological circumstances, the values of dependency immediate roof critical with (IRCW) and pillar management are used in conjunction with each other.
