Abstract Narrow coal pillar gob-side entry driving technology was adopted to 2120 working face during air way digging process in Julong Mining Corporation Ltd., reflecting increasing depth of mining and tense extracting joining. Reasonable coal pillar size, cross section shape of roadway, supporting form and construction method were determined in goaf side arrangement working face. It made social and economic sense to reduce coal resources loss and guarantee normal mining cohesion.
