露天开采地下采空区穿爆技术研究与应用

通过对露天开采地下采空区对穿爆工作的影响原因研究,发现影响生产的关键问题。采用空区探测技术首先确定空区的空间状态,然后根据空区的几何形态对不同部位采用各异的穿孔方案,经过精细的单孔药量计算,形成精密的起爆网络图,进而解决制约露天生产的技术难题。

Based ou the open pit mining of underground goafblasting work of reason, found the key issues that affectpruduction. The goal detection technology firstly determine the spatial state space area, then according to the geometry ofthe empty area on different parts of the different perforationscheme,single hole charge after careful calculation, the formation of initiation network precision, and solve the problem of mining production control technology.
