硐室爆破开采堆石坝坝料生产性试验研究

Experimental Study on Mining the Dam Rocks for Rock-fill Dam by Chamber Blasting

采用硐室爆破方法开采堆石坝坝料是本文所研究的主要内容 ,运用爆破理论进行爆破设计 ,有效地控制爆破料的粒径、级配 ,提高开采强度和爆破效率 ,减少大块率 ,降低开采成本。

The blasting design on the basis of blasting theory was utilized to effectively control the size and gradation of blasted rocks, to improve the mining intensity and blasting effectiveness, and to lower the boulder yield and mining cost etc.
