东庞煤矿通风系统优化研究

Optimization research of ventilation system of Dongpang coal mine

为了改善东庞煤矿的通风系统,在通风安全学的理论基础上,在深入分析东庞煤矿的通风系统的不足和缺陷后,提出两个通风系统的改造方案。对两个方案进行总体描述,然后对两个方案分别进行了工程对比、技术可行性分析和经济可行性研究。对比结果表明:方案二动用工程更少,技术可行性更强,经济上更为合理。此方案可以服务到矿井结束,期间不用做大的通风系统调整,具备保障东庞煤矿生产原煤400万t/a的通风能力。因此,经理论分析与模拟结果的验证,建议采用方案二。

To improve the ventilation system of Dongpang coal mine ,bases on the theory of ventilation securi-ty, it analyses deeply the shortages and defects and puts forward two retrofit schemes.And it describes the schemes roundly , makes the project comparison , and analyses the technical and economic feasibility.Compar-ison results show that the second scheme has less use of engineering , stronger technical feasibility , more rea-sonable economy.The scheme serves to the end of the mine and has the ability to guarantee the production of the row coal up to 4 million tons a year without making big adjustments.Therefore , the second scheme is rec-ommended through theoretical analysis and simulation verification.
