摘要
西山石膏矿采用房柱法开采过程中间柱、顶柱预留较大,间距偏小,造成了资源的浪费。结合地质条件,设计采用崩落法回采工艺,缩小间、顶柱尺寸,利用围岩作为顶柱以支撑顶板,综合回收利用板窑凹矿区的边缘资源,提高资源利用率,增加经济效益,同时对类似矿山具有一定的示范意义。
Room-and-pillar method which used in Xishan gypsum mine caused the size of sill pillar and barrier pillars are much larger and the spacing is a little small, so it takes a waste of resource. Combined with the geological conditions, designed the caving method. It shrunk the size of sill pillar and barrier pillars, used the surrounding rock to support the roof, recovered the edge resources of Banyaoao mine, improved the resources utilization rate, increased the economic benefit and also had a certain demonstration significance to other similar mines.
