Discussion on Temperature Control Method and Air Condition System in Xieqiao Underground Coal Mine

阐述了我国煤矿遭受水害的现状、类型、原因及危害性,提出了"管理是中心,工程是基础,科技进步是关键"的原则,对不同水害类型的矿区采取不同措施,防止重大水害事故的发生,减少水害损失,保证煤矿安全生产。

Xieqiao Mine is a high temperature and hot disaster mine with an annual coal production of 4 million t.This paper has a com- prehensive analysis and discussion on the mine temperature control method.And the results of the analysis and discus- sion have shown that the ventilation line is too long,the ventilation quantity and negative pressure are too high,the feasibility of the ventilation and temperature control meth- ods is poor from view of the technology and is not rational from a view of economy.But what a kind of air condition system will be relatively rational reliable,economic and ef- ficient for the mine application,it should be determined base on the mine certain conditions and characteristics,and the detailed comparison of the technology and economics. Base on the characteristics of the mine development in Xieqiao Mine and the analysis and comparison of several air condition systems,the application of panel concentration air condition system will have more obvious advantages.This technology will be reliable and more independent with flex- ible application and low initial investment.All can meet the Chinese conditions and the technology status of mine tem- perature control in China.
