掘进巷道瓦斯分布与风筒位置关系的模拟研究
The Simulation Research of the Relationship between Gas Distribution and Air Duct Position in the Tunneling
摘要
Abstract
The objective of this thesis ,is to build a three dimensional model of tunneling that took advantage the simulation software of fluent and the basic theories of computational fluid dynamics.This thesis describes that simulated tunneling air duct layout position would impact the law of gas distribution by employing RNGK-e equation model and component distribution equation. By researching, we get results, which gas dis-tribution less wave, meanwhile low content gas top become and high content gas bottom become when air duct is put on the top of tunneling. Through the top layout way of air duct, the danger coefficient of gas accu-mulation become low. And that way also can prevent effectively gas accumulation. It is great for gas attenua-tion to put air duct on the top of tunneling. Gas distribution has greater gradient when air duct is put on the side of tunneling. The side layout way of air duct cause easily gas accumulation in the part of tunneling.关键词
