| 摘 要： | 80年代以来,我们针对不同的应用条件先后进行了VCR采矿法、阶段台阶崩矿采矿法、阶段挤压爆破单步骤开采工艺、束状阶段深孔盘区崩落采矿法等不同的大直径深孔采矿技术方案、工艺技术、应用条件、落矿方法、爆破作用控制技术等研究工作以及应用试验。实践证明,上述研究结果有很强的适用性,技术先进,经济效益显著。

| Abstract: | Since 1980's, different underground large-diameter longhole mining methods have been tested by our institute and successfully applied to different conditions. These methods include VCR mining, bench-and-trail method, single-step tight-face blasting stoping and bunch longhole panel caving, etc.
In this paper, the technical characteristics, application conditions, blasting processes, blasting-effect control and technical-economical effects of above-mentioned mining methods are briefly introduced. |
