Based on the great thickness of coal seam in Tashan Mine, narrow pillar mining technology was adopted to liberate more coal resources from coal pillars. In this paper, the research status of narrow pillar technology was analyzed, and the main problems of the narrow pillar mining technique were solved by theory research. The method and technical route of this study was offered in final. The results have great reference value to the fully mechanized sublevel caving with great mining height in similar conditions.
