摘要
Abstract
In shanjiacun coal mine of Shandong yulong coal mining group, the mining limit of thin bedrock under quaternary unconsolidated aquifer increased from-250m to-180m, through the experimental research on 3#coal, and the fully-mechanized working face realized mining safety. Based on the original design of making 70m water-proof-pillars, through the research analysis and ifeld exploration, we determined to make 45m sand-proof-safety-pillars. In this way, great economic beneifts was made, and also a scientiifc basis was offered for making a reasonable mining limit in Yanzhou mining area.关键词
