侧翼推进在地下转露天矿采空区处理中的应用

Application of Wing Propulsion in the Treatment of Underground Turn to Open-pit Mine

针对地采转露采过程中出现的高危空区,在崩落法无法安全实施的情况下,采用束装孔侧翼推进的方式处理采空区,达到安全、可靠的目的。以1310空区为例,详细介绍了束装孔控制爆破的实施过程,为复杂空区处理提供了一条新的思路,对今后空区处理工作具有较高的参考价值。

According to the high risk area appearing in the process of underground ming turn to open-pit mining, under the condition of the caving method cannot be implemented security, the tie holes wing propulsion is used to deal with the gob, the purpose of safe and reliable is received. Taking the 1310 gob as an example, the implementation process of the tie hole controlled blasting is described in de- tail. It provides a new train of thought for the process method of gob, and has a high value on the future work in the field.
