中文摘要: 某地下金矿目前已经进入开采阶段,为降低开采过程中钻爆和铲装成本,有必要对爆破块度级配进行优化研究,并得到较合理的上向扇形炮孔爆破块度,从而优化爆破参数。对某地下金矿目前正在爆破回采的不同采区进行铲装时的爆堆拍照,对相应爆破参数下的钻孔数量和炸药用量、铲运环节等成本资料进行收集,并运用Split-Desktop4.0软件,得到不同采区的钻爆与铲装成本与平均块度的关系公式,建立成本模型。成本模型结果显示:基于钻爆与铲装环节的某地下金矿经济合理爆破块度区间为21~24 cm,对应的主要爆破参数为:孔底距约1.9 m,排距约1.5 m,孔深5~14 m。研究结果节约了矿山的生产成本,提高了生产效率,为相关研究补充了理论依据。创新点:将计算机爆破块度分析软件,运用在矿山生产成本优化中,并以此为出发点,探究对应的合理爆破参数,为相关研究提供新思路。
Abstract:An underground gold mine has entered the mining stage. To reduce the cost of drilling, blasting and shovel loading in the mining process, it is necessary to optimize the blasting fragmentation gradation, and obtain a more reasonable blasting fragmentation of upward fan-shaped blast holes to optimize the blasting parameters. The blasting piles of different mining areas under blasting mining in an underground gold mine were photographed, and the cost data such as the number of boreholes, explosive dosage, and shovel transportation link under the corresponding blasting parameters were collected, and use the Split-Desktop4.0 software, get the relationship formula between drilling and blasting, shovel loading cost and average block size in different mining areas, and establish the cost model. Results: The cost model results show that the economic and reasonable blasting fragmentation interval of an underground gold mine based on drilling, blasting and shovel loading is 21~24 cm, and the corresponding main blasting parameters are: hole bottom spacing is about 1.9 m, row spacing is about 1.5 m, and hole depth is 5~14 m. It saves the production cost of the mine, improves the production efficiency, and supplements the theoretical basis for relevant research. Innovation: Apply the computer blasting fragmentation analysis software to the optimization of mine production cost, and take this as the starting point to explore the corresponding reasonable blasting parameters, so as to provide new ideas for relevant research.
