Abstract:
The stone mines in China have features of large quantity, small scale and wide distribution.However, it is lack of specification requirement and guidance scheme for stone green mine construction, the process of construction is relatively slow, at present, there are only five national stone green mines, which occupy about 0.4% of the total quantity of national green mines and less than 0.1% of the total quantity of stone mines.Aiming at these problems, the core element and basic requirements of stone green mine are clarified in mining environment, development mode, comprehensive utilization, energy conservation and emission reduction, digital mine and enterprise-locality harmony through comparative analysis, literature research and enterprise research.On the basis of that, major technical solution of stone green mine construction is proposed.Sawing mining method and its advanced equipment should be applied to increase mining rate of stone block.Mining wastes such as debris, scrap, stone powder, topsoil and residue should be utilized comprehensively to improve the comprehensive utilization rate of the mineral resources.Ecological restoration methods for high and steep slope such as net-suspended spray seeding, planting slot, laddering greening and climb up and hang down the three-dimensional greening should be applied to restore mining geo-environment.The digital stone mine synthetic system includes one data center and four application platform, which can achieve visualization of production process, monitoring and scheduling in real-time, production information transparency and safety production standardization.Through the discussion in this paper, it is expected to lay the foundation and provide guidance for promoting the construction of green mines in stone industry.
