摘　　要：为研究煤层群开采方案,以潘三矿西三C组煤下部采区11_(-2)煤和13_(-1)煤开采顺序为研究对象,对传统从上向下依次开采煤层存在问题的研究,提出了先开采下层11_(-2)煤后开采上层13_(-1)煤的方案。根据顶板岩层"三带"规律及突出危险煤层瓦斯治理模式研究表明,开采下层11_(-2)煤再开采13_(-1)煤是可行的,能够实现工作面安全、高效、快速投产,同时能减少投资等目标。In order to study the mining scheme of coal seam group, taking the 11（-2） Coal and 13（-1） coal mining sequence in the lower coal mining area of the three C group of the pan three mine as the research object, the scheme of mining the upper layer 13（-1） coal after mining the lower 11（-2） Coal is proposed. According to the ＂three belt＂ rule of the roof rock stratum and the study of the gas control model of the outburst dangerous coal seam, it is proved that it is feasible to exploit 13（-1） coal in the lower layer of 11（-2） Coal and to realize the safety,high efficiency and rapid production of the working face, and reduce the target of investment.
