摘要
针对神火集团葛店煤矿N31062、N31063两采面特殊的开采条件,研究确定了上下采面联合开采方案。根据上下采面的特点并借鉴国内外近距离煤层联合开采的先进经验,制定了合理的回采工艺和上下煤层开采的走向错距。并通过加强现场管理使联合开采获得了成功,节省了支护费用,缓和了采区接替紧张的局面。
According to the special mining conditions of No. N31062 and N31063 coal mining faces in Gedian Mine of Shenhuo Group, the paper studied and made a combined mining plan with up and down coal mining faces. According to the up an d down coal mining face features and the advanced experiences of the combined mining for seams with a closed distance at home and broad, the paper rationally set the mining technology and the alternate distance for the up and down seam mining. Also with the site enhanced management, the combined mining had a successful operation with a saving in the support cost and a relaxation the tension of coal mining faces alternated.
