矿井瓦斯抽采浓度影响因素研究分析

Study and Analysis of Factors Affecting Gas Extraction Concentration in Coal Mines

以某企业煤矿开采为例,分析了影响瓦斯抽采浓度的相关因素,结合钻孔瓦斯气体流动走向,整合相关参数并建立漏气模型,通过模型与数据分析,明确了瓦斯抽采浓度的主要影响因素,提出了可应用于实际作业中提高瓦斯抽采浓度的具体措施,并通过工程实践验证其效果。

Taking the coal mining of a certain enterprise as an example,this paper analyzes the relevant factors that affect the gas extraction concentration,Combined with the gas flow in the borehole,integrates relevant parameters,and establishes a gas leakage model.Through model and data analysis,the main influencing factors of the gas extraction concentration are identified,specific measures that can be applied to actual operation to improve the gas extraction concentration are proposed,and their effects are verified through engineering practice.
