摘要
Abstract
the use of gob-side entrydriving method in fully-mechanized sublevel caving mining face in Tangkou mine brought the safety management dififculties, such as one ventilation and three prevention, water prevention and control, and rock burst, by the contrastive analysis of three kinds of width coal pillar of 6m, 8m, 30m, in this paper, found out the optimum remaining width that is not only beneifcial for safe production, also for the recovery of coal resources, and formulated the corresponding safety control measures to ensure the safety of working face in mining period.关键词
