摘要
通过介绍云南省纳佐煤矿受村庄、河流、断层构造、煤层间距近等复杂条件影响下的优化设计方案,提出了适合该矿井开采的走向长壁采煤法方案,并选择了工作面上行式接替方案,满足了矿井生产需要。同时指出目前矿权设置方法在近水平煤与瓦斯突出矿井中存在的问题及其建议,对近水平煤层的同类矿井设计有着积极参考的意义。
With the optimized design alternative of Nazuo Mine,Yunnan under the influences of the villages,river,fault structure,closed distance between seams and other complicated conditions,a strike longwall coal mining method alternative suitable for the mine was provided.An ascending type connection alternative of the coal mining face was selected to meet the requirements of the mine production.The paper pointed out the problems and proposals of the present mine property setting method existed in the mine with the horizontal coal and gas outburst,which would have active references to the design of the similar mine with horizontal seam.
