Abstract: Aiming at the large inclination down-hill isolated pillar, we propose strike longwall mining scheme and the division method of stress concentration region and controlling measures of risk. Based on the occurrence condition of down-hill coal pillar in west mining area of Hanzhuang Coal west wing, we comparatively analyze the advantages and disadvantages of inclined longwall and longwall mining plan, adopt the downward trend of long wall mining down-hill isolated coal pillar of 4th and 6th coal seam, and research and design layout of roadway. Through the numerical simulation of working face mining, we divide stress concentration risk region. In the mining process, in view of the high risk region, we adopt a large diameter and combine with drilling loose blasting, which achieves safety mining of the down-hill isolated coal pillar.
