1996-2006 Construction of metal mine ventilation system and its progress

Conditioning, ventilation Mine optimization and optimization of ventilation equipment, etc. With the progress of the new proposed global optimization of complex ventilation network and the ventilation system selection expert system decision making,abercrombie et fitch, artificial intelligence into the experience of making decisions, and in practice applied. Evaluation of safety and reliability of the ventilation system and ventilation system airflow stability analysis methods have some progress, technology management and mine ventilation systems provide important information for disaster prevention and relief. 2.8 Construction of small private mines ventilation system and the technological transformation of Statistics 11, the end of 2004, China's total of 100,640 small-scale non-coal mines (including building materials, non-metallic mining, etc.). Since the state organs at all levels of production safety supervision and management of small private mines and further intensify supervision, to implement a series of scientific regulation. Small Private metal mine ventilation system construction and transformation has been rapid development. According to the actual situation of mine ventilation system, the basic uniform or out of the main fan ventilation system partition type work, with initial improvement of mine ventilation conditions, and promote the safe production. However, due to a huge number of small mines, mine development more complex mining conditions, mine has not been established many current mechanical ventilation system, the formation of a big hidden mine safety, ventilation system and its transformation imperative, safety production supervision at all levels should management agency under the unified guidance, and actively and steadily carried out. The focus is a qualified certificate to be organized units of the design of the ventilation system design, active ventilation and technical training of security managers and workers, to establish a scientific management system, strictly enforce the 3 Conclusions (1) The main technical indicators of the ventilation system was significantly improved with efficient air flow rate of 6 average 71.57%, average fan assembly efficiency 74.14%. Significantly improve the underground ventilation conditions, and promote the safe production. Annual saving of 3459.51X10kW · h, energy saving and efficiency significantly. (2) mine ventilation theory and technology has improved continuously, initially formed a relatively complete theory of metal mine ventilation shaft ventilation system and the unique technology. For mine safety and miner has made a significant contribution to labor protection. (3) various types of multi-level ventilation technology, sub-domain partition - cell sub-system ventilation technology, mine were warm-up pre-cooling airflow technology, the use of air curtain air flow control technology to further promote the use of technology has made significant economic benefits. (4) formed a self-saving innovative products on the mine ventilation system fan series construction and technological transformation, provides an important guarantee. (5) construction of small private mines ventilation system is particularly urgent, long way to go. Must strengthen the supervision and management, enrichment technology, strong management and staff to improve the safety of technical quality, and establish a scientific management system and promote safe production.
