| 摘 要： | 回收边角煤柱是衰老矿井延长服务年限的有效途径。近年来不少老矿井都在尝试回采残留煤柱,并取得了不少经验,对延长矿井服务年限具有重要的经济价值。白庄煤矿自2009年以来,为了提高矿井回采率,延长矿井服务年限,陆续对矿井边角残留煤柱进行了开采实践,在煤柱工作面分类、回采工艺选择、巷道布置、回采技术等环节进行了有效的尝试,达到了争产争效的目的,并取得了良好的经济效果,对相似条件下残留煤柱回采具有推广和借鉴作用。 |

| Abstract: | Boundary coal pillar recovery is an effective way to prolong the service life of aging mines.Many old mines have tried to recover residual coal pillar in recent years and have made a lot of mature experience,which had important economic value for prolonging the service life of mines.In order to improve mining recovery and prolong the service life of mines,there has been continuous mining practice on boundary coal pillar in Baizhuang Colliery since 2009.Effective attempt such as classification of coal pillar working face,mining technology selection,roadway layout and mining technology,etc.has been made for the purpose of high production and high performance,which achieved good economic effect and had promotion and reference for residual coal pillar mining under similar condition. |
| Keywords: | residual coal pillar support mining technology |
