摘要
放矿工作是无底柱分段崩落法的核心工作,为保证大红山铁矿一、二期生产的正常衔接及大参数回采需要,开展大参数放矿试验,通过单体及立体放矿试验,得到各参数组合条件下的回贫指标,从而确定最佳放矿步距及进路参数,为生产实际提供理论指导依据。
Ore drawing is the core of Non-pillar sublevel caving. In order to ensure the cohesion of production process phase I and phase II of Dahongshan iron mine and meet the requirements of the large parameters recovery, the stoping indicators under the condition of all parameters combination and the best ore interval and route parameters are acquired by conducting of experiments of the large parameters ore drawing and monomer and three-dimension ore drawing. So, the test results can provide some basises of theoretical guidance for the actual production situation.
