摘　　要：为了确定炮采工作面瓦斯涌出量的来源及定量构成,确定合理通风设计和制定瓦斯防治措施,通过现场单元法实测,考察工作面漏风量的分布规律及瓦斯涌出量的定量构成,研究工作面风量与风排瓦斯量、采空区漏风量与采空区瓦斯涌出量的关系。研究认为,炮采工作面风流携带瓦斯量沿倾向呈现逐渐增大的趋势,到回风巷端部位置达到最大,瓦斯涌出量增加幅度较大的区域位于工作面上部。In order to determine the source of gas emission and ration composition of blasting mining face,determine a reasonable ventilation design and development of gas control measures,measured through on-site element method to study face amount of air leakage distribution and composition of gas emission in quantitative research the realationship between the face air volume and air emission gas volume,and the amount of air leakage and the goaf gas Emission.Studies suggest that blasting mining face amount of airflow to carry the gas along the trend of gradually increasing tendency to present to the return air,Lane End position reached a maximum rate of increase of gas emission in a large area is situated at the surface of the work of the Department.
