Abstract:

The extent to ensure ventilation for underground mines depends on the design, as well as network computing wind ventilation equipment. I Khe Cham Coal Mine, is in Phase III investment activities under the project to expand production. In the coming years, network change and wind fields will become more complicated due to 4 stations use fans to ventilate the mine. This paper proposes the application of specialized software to improve reliability while enhancing network computing wind fields. Calculation results allow making recommendations on the use of fan-No.30 2K56 engine with 400kW ventilation to reduce costs in the early stages of production and expanded. 1250kW engine capacity will be needed in the future to use the enhanced mine catches as planned.
