Dongtan coal mining technology to carry out research for sustainable development


Power supply capacity and 6 million tons, gradually increase from the Liaison Office for ore mining and the ratio of mining to reduce dependence on the people; final form 12 million tons and 8 million tons of mining capacity of the supply capability to meet all rely on self-collected and the United Office for the mine to meet production needs, and stable supply of ore, ore to minimize costs. 5.2 bauxite exploration work to strengthen and improve the resources from the early years of the guarantee has been identified in the Al:}: mining and depth of around 500m deep or shallow ore belt in order to carry out geological exploration work, the effect obvious. For this reason, in these regions (especially the windows ore region) through increased investment in geological exploration, to submit additional, higher grade reserves of bauxite sales to increase bauxite resources to ensure life and geology and mineral resources of vanadium J two grade to ensure the sustainable development of Central Plains branch. 5.3 optimize its structure to adjust its alumina production capacity sales oxide structure in alumina production to meet the chemicals under the premise of phasing out energy-intensive part of the enhanced sintering capacity; in the dressing Bayer basis of existing production capacity on the timely expansion of one or two 350,000 t ore production line Bayer, Bayer beneficiation to improve the proportion of production capacity,replica oakley sunglasses, to ensure that Central Plains Branch oxidation off the competitive advantage of manufacturing costs. Meanwhile,GHD Glätteisen günstig, Bayer beneficiation capacity improvement, can consume more in the low-grade ore,ed hardy uk, mine I will help improve the recovery rate on the extraction of J, to reduce the cost of ore mining and alumina production costs,Oakley sunglasses sale, enhance the competitiveness of Central Plains branch, also extend the bauxite resources to ensure service life.

Dongtan coal mining technology to carry out the recent study on sustainable development, Yanzhou Mining (Group) Company launched a large Dongtan coal mine town continued development of mining technology research, through the exploitation of the computer simulation, the mining technology and mine can be sustainable development of organic combine, to avoid hair Ah tendon had Ah the research use of discrete fuzzy theory, the geological conditions of coal mining evaluation model, including _lr affecting 1: The seven major mining claims (the minutes flash l5 sub prime), occurrence conditions of coal segment analysis and mining town of the parent, to 1: mining technology, production management decision support and exploitation of results l provide the basis for prediction. Ming Qiu study: long-term mine within the next II_Il caving is still the dominant foot: [Art, in vain is not suitable for rice 15 years of caving City recoverable reserves of nearly 80 million t, coal thickness 5.0-9.5m; 2.0m following the use of integrated mechanized coal mining in the ... ji They are based on actual and simulated results of mining analysis that coal caving: T: as the yield level and efficiency are high, middle circle arrows caving based high-intensity set I meet production requirements; present, production of caving to drop f The main problems in the system, a lack of adequate external, need to strengthen the technological transformation; caving will further update the character set, strengthen management, engineering ffifJf Nissan average 20,000 t or more, annual output of 600 million t of mine above is entirely possible. Mine based on geological evaluation and adopt a master ... a quasi-public funds Lai assisted with the principles of listening, group proposed J, with a variety of ways. Through simulation analysis, obtained a practical continuation of the program, the main mining allocated a hearing, a quasi-character Jf [f better able to meet the high stability of the mine j, one side can achieve a mine or a mine production of two NAO f mode. Accordingly, the rational development of strength Gai mines may be set for 550-700 Wan t / a, Laos to its production according to market demand conditions for annual control, enable enterprises to adjust the relationship between market demand l {| has a larger adaptability and initiative.
