混凝土垫层削壁充填法在急倾斜极薄矿脉中的应用

Concrete cushion resuing method in steeply inclined thin vein in application

随着矿产资源的日益枯竭,目前我国加大了对于急倾斜极薄矿脉的开发力度,但是由于急倾斜极薄矿脉自身结构特点的限制难以使用传统开采工艺进行开采工作。混凝土垫层削壁充填法作为一种新型的开采技术,可以有效提升极薄矿脉开采过程的安全性同时避免出矿贫化问题,近年来被广泛应用于急倾斜极薄矿脉开采之中并取得较好的效果。

With the increasing depletion of mineral resources, our country has increased the development of the steep and thin vein, but it is difficult to use traditional mining technology because of the limitation of the structure characteristics of the steep and thin vein. As a new mining technology, the concrete cushion and backfill method can effectively improve the safety of the extremely thin vein mining process and avoid the ore dilution problem. In recent years, it has been widely used in the mining of steep and thin ore veins and has achieved good results.
