基于漏风规律的采空区瓦斯的治理

Coutrol of Goaf Gas Based on Air Leakage Law

为进一步提升综采工作面生产安全性,针对1504工作面采空区上隅角瓦斯积聚而导致的煤炭自燃的问题,在对1504工作面地质条件、瓦斯以及水文条件分析的基础上;基于FLUENT软件对1504工作面的漏风规律进行分析;结合漏风规律制定了瓦斯治理方案,并通过实践生产验证了瓦斯治理方案的可行性和有效性。

In order to further improve the production safety of the fully mechanized mining face,in response to the problem of coal spontaneous combustion caused by gas accumulation in the upper corner of the goaf of the 1504 working face,based on the analysis of the geological,gas,and hydrological conditions of the 1504 working face,this paper analyzes the air leakage pattern of 1504 working face based on FLUENT software.A gas control plan was developed based on the law of air leakage,and the feasibility and effectiveness of the gas control plan were verified through practical production.
