Ventilation System Of Coal Mine Reform And Optimization Research

The stand or fall of mine ventilation system can directly determines the mine safety and efficient and orderly production, the mine ventilation system is an important part of the mine production, mainly includes mainly includes the main ventilator, underground roadway and its auxiliary ventilation regulating all facilities. In order to ensure optimal mine ventilation system, the need for transformation and optimization of mine ventilation system research, this article is in reading and consulted a large number of literature and its engineering practice, under the condition of a mine in north China as the research background, research the basic theory of mine ventilation and the mine ventilation system reform and optimization technology, a detailed investigation of mine ventilation system, determination of mine ventilation resistance and fan performance appraisal, with multiple solutions, through numerical simulation of ventilation network solution of various schemes and contrast(working condition of main ventilator, mainly use the wind tunnel, mainly use the wind place, economic rationality and technical feasibility, etc.), ultimately determine the optimal ventilation scheme.Based on mine ventilation system optimization and transformation, which greatly improved the conditions of the mine ventilation, to achieve optimization of mine ventilation resistance and airflow and ensure the underground personnel each position of the personal safety, ensure the production of the mine safety and efficient and orderly.
