Chapter I General Provisions Article 1 These Measures are formulated in order to rationally develop mineral resources, develop chemical mines at a high speed, maintain a balanced, sustained and high yield, and realize the unified management of mining (stripping) technology in chemical mines. Article 2 The annual mining (stripping) technical plan is a comprehensive technical document to implement the production (including development and deepening) tasks assigned by the competent department according to the actual situation of mine mining (stripping) and the rationality and possibility of technology. Mining enterprises shall, according to the annual mining (stripping) technical plan, formulate plans for production, finance, labor, material supply, equipment operation, air supply and water supply, transportation and technical measures, and organize and direct production. The production of chemical mines (including approved township mining enterprises) must be under the unified leadership of mine managers, fully mobilize the masses, rely on technicians, workers and leading cadres, organize the preparation of annual mining (stripping) technical plans, and conscientiously implement them. Article 3 When drawing up the mining (stripping) technical scheme, we must conscientiously implement the national technical policies on mining, adhere to the principle of "mining (stripping) while digging (stripping) first", and rationally arrange the proportion of mining (stripping). Keep the third-grade ore quantity (open pit mine is the second-grade ore quantity, the same below) to reach the shrinkage quota to ensure the normal continuation of production; Carry out the principle of "mining both the rich and the poor, mining both the difficult and the difficult", adhere to the formal mining (stripping) order, and effectively develop and utilize mineral resources. Article 4 The mining (stripping) technical scheme must implement the policy of safe production, correctly handle the relationship between production and safety, and implement various safety technical measures to ensure safe production. Article 5 The preparation of the annual mining (stripping) technical plan shall aim at the problems and weak links existing in the production of the enterprise, strengthen scientific research in mines, overcome technical difficulties in production, popularize and apply effective new technologies, new processes and new equipment, continuously improve the technical level of mine production and promote the development of mine production. Chapter II Compilation Principles and Basis Chapter II Compilation Principles and Basis Article 6 The annual mining (stripping) technical plan shall be compiled on the basis of the production control indicators issued by the competent department of the enterprise, combined with the current situation of mining (stripping) and long-term planning. Article 7 When drawing up the mining (stripping) technical scheme, major technical issues such as mining sequence, development scheme, mining (stripping) layout and mining method should be studied. ) should be more scheme comparison, focus on the correct opinions of the masses, approved by the mine leaders. Eighth technical and economic indicators in the preparation of mining (stripping) technical plan should adopt the average advanced quota reached by this mine, and be consistent with the advanced level of the same type of mine. Article 9 To balance the production capacity, it is necessary to carry out a unified balance according to the third-grade ore quantity, stope working face, labor force and production links held in the current period, and take the comprehensive production capacity achieved after taking active measures as the basis. Tenth according to the characteristics of mine production variability, continuity and cohesion, the preparation of mining (stripping) technical plan must actively balance the following:
1. The proportion of tertiary ore and the balance of output.
2. Balance between the progress of development, mining and cutting (stripping) projects and mining speed.
3. Mining volume, ore supply and the selected raw ore type, grade and concentrate quality plan are balanced.
4. The balance between mining volume and working face capacity.
5. According to the requirements of mining (stripping) sequence or selected ore type and grade, as well as the requirements of commodity ore quality collocation, it is planned to balance the proportion of ore mined by various mining methods and its mining intensity.
6. Labor organization includes the balance of main technical jobs (including the training plan for skilled workers).
7. The capacity of major equipment, spare parts and their maintenance plans are balanced.
8. Capacity balance of water supply, power supply, wind supply and steam supply system.
9. Capacity balance of transportation and lifting system.
10. Balance of ore production, supply and sales.
1 1. Balance of main raw materials. Eleventh mining (stripping) technical plan reflects the overall plan of mine production, in order to make the plan have a positive and reliable basis, we must correctly handle the following eight proportional relations.
1. Proportional relationship between mining, mining and ore supply (proportional relationship between stripping and ore replacement).
2. Proportional relationship of mining quantity of various ore types and grades.
3. The proportional relationship between mining preparation, cutting (stripping) and the number of working faces.
4. Proportional relationship of ore quantity mined by various mining methods.
5. Proportional relationship between pillar mining and room mining.
6. The relationship between mining engineering and ground pressure control; Relationship between mining and stripping engineering and slope treatment.
7. The relationship between production and maintenance.
8. Proportional relationship between direct production personnel and auxiliary production personnel, production personnel and non-production personnel. Twelfth in order to continuously improve the mining (stripping) method and carry out technological innovation, enterprises can designate a working face as a test working face in the annual mining (stripping) technical plan. Its output is not included in the annual plan, and its efficiency is not involved in the annual calculation and assessment. However, it is necessary to do a good job in individual construction design and construction organization plan, strictly follow the design and construction, accurately calculate various technical and economic data, and make a technical summary. New technologies and methods must be appraised by relevant technical appraisal meetings convened by the chief engineer before they can be popularized and used.
