(1) Characteristics of the mining project The distinctive feature of the mining project is that the project is determined by the conditions for the occurrence of mineral resources, and the underground works and the ground works associated with it are determined by the mining method and the various ways of achieving the mining method. The request is decided. Mining projects generally include mine engineering (or open pit mining) and various ground engineering and related industrial and civil construction projects. At present, domestic large and medium-sized mining projects are comprehensive engineering projects, generally consisting of multiple individual projects and dozens or even hundreds of unit projects. The entire project construction period is 3-8 years, or even longer, and the investment amount is mostly Between 10 and 6 billion yuan, and the mining project relies heavily on the particularity of geological conditions. Therefore, mining projects are in principle high-investment, long-term, high-risk projects.
(II) Characteristics of the general contracting process of the mining project Generally, the general contracting project can start from any stage of the project establishment, feasibility study, preliminary design or construction/construction stage until the completion of the project. However, according to the National Mineral Resources Law, China implements a government approval system for mine development. The mining area, mine design or mining plan, production technical conditions, safety measures and environmental protection measures must be approved after being examined and approved according to law. Mining engineering projects must also follow this principle. They must complete project approval and feasibility study report approval including government organizations before they can enter the substantive construction phase of the project. Therefore, the timing of the general contractor’s introduction of mining engineering projects can only be After the feasibility study report was approved. This determines that the beginning of the general contracting process of the mining project can only be the preliminary design stage or the construction drawing design stage. At present, most of the contracting is started from the preliminary design stage.
Construction general contracting content (c) the characteristics of mining engineering subcontracting of mining projects, including mine construction (topsoil was stripped for construction veins open-pit mining), mining and beneficiation plant construction, mining and processing plant machinery and equipment, electrical, control, installation and construction, engineering and construction field area roads, railways, civil construction and so on. When special construction methods are required for mine construction, such as special well construction, the construction team involved needs more professionalism. Therefore, the subcontracting of mining engineering projects has many characteristics including professional types, wide content, strong professionalism and relatively complicated management.
(IV) Characteristics of general contract management of mining projects Due to the large investment and long construction period of mining projects, there are many uncertain factors and high risk of general contracting, especially the mine part. Therefore, it is relatively difficult to strictly implement the management measures of general contracting and achieve the goal of general contract management of mining engineering projects. It is this characteristic that the development of engineering general contracting in this field is still immature. Most of the current general contracting in the field of mining engineering is in the ground industry project.
