多规格石高强度开采矿山开拓系统的三维规划设计与施工

为了保障多规格石高强度开采矿山的石料供需平衡和安全高效生产，利用三维数字矿山软件进行矿山开拓系统的规划设计与施工监管。以舟山绿色石化基地大、小鱼山岛多规格石高强度开采工程为背景，采用3Dmine软件建立了矿区的三维数字表面模型，并进行了运输道路优化设计、开拓工程量计算等，最后进行动画模拟，分析露天矿山开拓系统的车—路协同效果，确保满足工程施工强度要求。实践表明：生成的开拓系统设计可视性好，有助于采场合理布局和石料科学调配，为多规格石的高强度开采施工奠定了技术基础。利用3Dmine数字矿山软件，设计多规格石高强度开采矿山的三维开拓系统，并将其应用于现场施工，有助于保障多规格石的供需平衡调配和矿山持续高效的生产管理。

Three-dimensional Planning Design and Construction of Multi-size Stone High-strength Mining Development System

In order to ensure the balance of stone supply and efficient safety production of multi-size stone high-strength mining mines，the three-dimensional digital mining software was used to carry out the planning，design and construction supervision of the mining development system.Based on the large-scale high-strength mining project of Yushan Island，Zhoushan Green Petrochemical Base，3Dmine software was used to establish a three-dimensional digital surface model of the mining area.The optimization design of the transportation road and the calculation of the amount of engineering were carried out，finally animation simulation was used.The car-road synergy effect of the open-pit mining development system was analyzed to ensure that the construction strength requirements were met.Practice has shown that the generated development system has good visibility，which contributed to rational layout of the stope and the scientific allocation of stone materials，laying a technical foundation for the high-strength mining of multi-size stones.It is convenient to build a digital model of the mine and to a large extent realize the virtualization operation.Three-dimensional mining software is applied in the whole life cycle of open-pit mines to carry out mining design，road construction design，blasting design，engineering quantity settlement，production plan formulation and other work，which reduces the labor intensity of personnel，improves the work efficiency，and improves the level of construction refinement.Three-dimensional mining software can solve the problems of traditional open pit mining design software （such as CAD software，et al.） such as complicated operation，poor visibility and difficulty in effectively communicating the construction intention，and improve the practical production guiding significance of design.Using 3Dmine digital mining software to design a three-dimensional development system for high-strength mining of multi-specification stones and apply it to site construction is helpful to ensure the balance of supply and demand of multi-specification stones and the sustainable and efficient production management of mines.
