(1) Comprehensiveness of mining engineering
Mining engineering is a large-scale comprehensive construction project, which is a huge system. Mining engineering has the characteristics of large investment, long cycle and complex organizational relationship. A delay in mining projects, the state may affect the deployment of the entire national economic plan; companies will add additional capital investment, project delays in recovery efficiency, resulting in significant economic losses; delay of the project will also add additional engineering and maintenance Cost, so the project has higher requirements for the continuity and sequence of the project.
    (2) Construction conditions of mining projects
    At present, the geological and hydrological conditions of the stratum are difficult to describe accurately; the geological survey level cannot fully meet the detailed and accurate geological data required for production and construction. Therefore, there are many variables in mine development and production. In the construction of mine projects, it is necessary not only to fully estimate and prepare for this situation, but also to make full use of management, technical, economic and legal knowledge and experience, to fully prepare the plan and avoid the loss of benefits.
    Complex and uncertain environmental conditions often cause major safety problems in mines, causing accidents and disasters. Therefore, considering the risk prevention and necessary emergency measures for these major emergencies is something that cannot be ignored in the implementation of mine engineering. Managers of mine engineering projects must attach great importance to safety management and environmental protection.
    (3) Production system of mining engineering
    Mining engineering is a complex and comprehensive project that involves entering underground production systems and contacting underground ground systems. Underground mine construction must go through the passage (wellbore, flat ring, inclined well, etc.) to the next step, and the scope, sequence, direction, speed and speed of the operation are subject to certain constraints. Therefore, the selected construction plan is closely related to the determination of the length of the construction period. The construction of a roadway on a critical line is good, bad, slow or adjusted, which will have an important impact on the entire project.
    The underground production system determines the layout of the ground production system and also affects the layout of the construction. A complete mining project involves the installation of large-scale production and construction equipment such as well engineering, civil engineering, and mining and mineral processing equipment. Therefore, in addition to the coordination of the relationship between the various links, the mining engineering project also needs to consider the spatial relationship between the upper and lower engineering and the constraints between the projects, as well as the mine (construction), soil (construction), and security (installation). The balance between projects.
    (4) The relationship between mining engineering and mining production
    Mining engineering construction is more closely related to mining production. For example, the construction content, form and utilization of equipment have many similarities with mining production operations. The construction of mining projects can often be completed by using some production facilities; the geological data obtained by mining engineering development is a more reliable basis during production. It should be handed over to production as required; construction units often use the construction process to train production personnel, which is often included in the construction enterprise's transfer of production.
