Explanation of Wording in this Code
1 General Provisions
1.0.1 This code was formulated in order to implement each law and regulation and policy of national development coal industry, promote and apply tried and true advanced technology and management experience of open pit mine, promote the scientific and technical progress, maintain the sustainable development of coal industry, improve the economic benefit of open pit mine, and achieve safety production and rational exploitation of coal resources.
1.0.2 This code is applicable to the pre-feasibility study, feasibility study and engineering design for the construction, renovation and extension of large and medium open pit mines. The pre-feasibility study, feasibility study and engineering design of small open pit mines may be carried out referring to this code.
1.0.3 For the constituent of open pit mine construction engineering project, the major works shall be the first and the principles of coordination based on specialization and socialization service shall be insisted.
1.0.4 For the engineering design of open pit mine, the economic benefit shall be the focus, and the sustainable development principle shall be put into effect, the high-yield and high-efficiency are the target, modern technical equipments shall be adopted, the informatization management shall be carried out and the policy of centralized production and environment burden reduce shall be put into effect. The engineering relation between short-term and long-term and short-term as the first shall be treated well.
