摘要
以安家岭露天矿生产实践为例,在深入分析总结安家岭露天矿工作帮及采场坡道形成方案及实践经验上,通过改进优化"采掘+推土机推送"坡道的作业方式,研究量化坡道工作任务量,形成的利用抛掷爆破法爆破前冲量来减少推土机推送量的坡道修筑方案,通过优化方案取得了良好的经济效益。
Taking Anjialing Mine as an example, based on the in-depth analysis and summary of the slope and stope formation scheme and practical experience in Anjialing Open-pit Mine, by improving and optimizing the operation mode of "excavation +bulldozer push"ramp, this article studies the quantification of the work amount of ramp, and forms the ramp construction scheme that reduces the bulldozer push amount by using the pre-blasting impulse of the throwing blasting method, and obtains good economic benefits by optimizing the scheme.
