Study on closed multiple-seam in the ascending mining technology
摘要
Abstract
The research concerns the closed multiple seam ascending mining technology (mining induced influenced coefficient 2.7) of Qinghemen coal mine, Fuxin mining area. Theoretical analysis, numerical calculation, similar material simulating experiment and on-site exploration are applied comprehensively in the integrity and continuity of 3-3 coal seam after the 3-2 coal seam mined. Based on the stress state and structure variation of 3-3 coal seam, the roadway layout is designed. The 3-3 coal seam mining practice indicates that when the above coal seam lied on the caving zone of low coal seam, the integrity of the above coal seam could still maintain continuity and integrity, because the formation of cracks and fracture could gradually "healed", which improved the integrity of coal to meet the conditions necessary for mining.关键词
