为解决工作面瓦斯涌出问题及为工作面瓦斯抽采提供依据,建立一种简便的工作面瓦斯涌出来源分析方法——瓦斯日报表法,将工作面瓦斯涌出来源构成分为开采层、邻近层和采空区三部分。以沁新煤矿22001工作面为例,基于工作面大量的瓦斯涌出实测数据,并采用分时段统计的方法,得到了工作面瓦斯涌出来源构成。
In order to solve the problem of gas emission in working face and provide a basis for working face gas drainage, this paper proposes a simple analysis way of the face gas emission source, called gas daily report method. This method divides the composition of face gas emission source into exploited layer gas emission, ad- jacent layer gas emission, and gob gas emission. Taking the 22001 working face in Qinxin coal mine as an ex- ample, the gas emission source structure in working face is obtained by the date of gas emission in working face, and by the use of statistical method in different period of time.
