According to the process or content of the proposed project, the construction organization design with different depth and scope should be prepared. The construction organization design of mining engineering projects can be as follows:
    (1) Overall design of the construction organization of the project (mine project)
    1. Nature
    The overall design of the construction organization of the construction project is targeted at the entire construction project. It is generally targeted at a combination of a production process system that uses a function or an entire yieldable product in a mining area or an electromechanical installation project, a building group, and the like. It is prepared according to the corresponding planning documents and site conditions after the approval of the overall project planning.
    2. Preparation and approval requirements
    The construction organization design of the mining area shall be compiled by the construction unit or entrusted by a qualified design unit or by the general contractor of the project. The design of the construction organization of the mining area is required to be prepared and pre-examined one year before the formal establishment of the project and the large-scale development of the construction preparation.
    (2) Individual project construction organization design
    1. Nature
    Individual project construction design targeted to individual projects, according to the construction and completion of the overall organization overall design and deployment of individual projects directly used to guide construction; suitable for new mine, beneficiation plant or individual projects constitute a standard railway, transmission and transformation Electrical engineering, mining area water source engineering, mining area machinery factory, general warehouse, etc.
    2. Preparation and approval requirements
    At present, the preparation of the construction design of a single project (mine) is mainly carried out in two stages. In order to meet the needs of project approval and future bidding work, the construction unit shall prepare a single project (mine) construction organization design, the content of which mainly focuses on the large construction plan and the total investment estimate of the total construction period, and the construction of the construction unit. The organization design is subject to approval by the higher authorities, and is generally completed 6 months before the large-scale start-up. After the bidding stage, the detailed construction organization design shall be prepared by the established construction unit or by the general contractor as the basis for guiding the construction. The construction organization design prepared by the construction unit only needs the construction unit to approve.
    (III) Unit construction construction organization design and construction technical measures
    1. Nature
    The unit organization construction organization design generally refers to unit projects that are difficult, complicated in construction technology, high in technical and quality requirements, and parts or sub-projects or professional projects that adopt new technology. For general well engineering, civil engineering, and electromechanical equipment installation projects, if there are reusable construction drawings, only brief construction organization design (technical organization measures or operational procedures) can be prepared.
    2. Preparation and approval requirements
    The unit construction construction organization design shall be prepared by the unit that undertakes the construction task, and shall be absorbed by the construction unit and the design department, and shall be submitted to the higher-level leading authority for approval by the preparation unit.
Construction technical measures or operational procedures shall be prepared by the construction area or engineering team responsible for the construction and reported to the Engineering Office for approval; some of the important projects shall be reported to the company (bureau) for review and filing.
    (4) Special project construction organization design
    Special project construction organization design is generally applicable to wellbore construction using special construction methods in mine construction projects, well roadway engineering using grouting and water control, and some special requirements and important work contents through coal mine and gas outburst roadway engineering. . Civil engineering projects that require construction during winter and rain periods, and foundation works that are treated by special methods are also applicable.
    (5) Preparation and approval of construction organization design
(1) The construction organization design shall be prepared by the project leader and may be prepared and approved in stages according to the needs. Some projects built in batches and batches have a long span, and some foundations, main structures, decoration and installation of electromechanical equipment are not completed by a general contractor. In addition, there are some special circumstances in the project. With the consent, the construction unit can prepare the construction organization design in stages.
(2) The general design of the construction organization shall be examined and approved by the technical person in charge of the general contractor; the design of the unit construction organization shall be examined and approved by the technical person in charge of the construction unit or the technical personnel authorized by the technical person in charge, and the construction plan shall be approved by the project technical person in charge; The difficult and sub-division (sub-item) project and the special project construction plan shall be reviewed by the technical department of the construction unit and approved by the technical person in charge of the construction unit.
