水平分条胶结充填采矿法在底柱回采中的应用与改进

Application and Improvement of the Horizontal-segmented Cemented-filling Method in Bottom Pillar Mining

为了安全高效地回采缓倾斜、破碎带型矿体底柱矿体,提高矿山资源回收率,在研究国内常用的底柱回采方法的基础上,通过湖南辰州矿业股份有限公司鱼儿山矿区现场回采试验研究,运用水平分条胶结充填采矿法对1505Ⅱ、1507Ⅱ矿块底柱进行了回采。试验结果表明,该方法生产工艺简单,作业安全,经济效果好,但是在提高作业效率和机械化水平方面仍有改进的空间。

In order to recycle the gently inclined and fracture zone bottom pillar safely and efficiently,and improve the recovery rate of the mine resources,it studied the domestic commonly used pillar recovery methods,then conducted the mining experiment in Yuershan mining area of Hunan Chenzhou Mining Co.,Ltd. It used the horizontal-segmented cemented-filling method in mining the 1505 Ⅱ and 1507 Ⅱ bottom pillars. The experiment shows that this method is simple,safe and economical,but there is still room for improvement in improving the operation efficiency and mechanization level.
