无区段煤柱工作面采空区的空气流动状况可用解析函数表示,并用图解法得到解析函数的数值解。图解的结果,对分析采空区内的瓦斯流动方向和可能发生自燃的位置是有益的。
The air flow in the gob of non-section coal pillar face can be expressed by analytic function and the numerical solution of analytic function can be obtained by graphic method. The graphical results are useful for analyzing the gas flow direction in the goaf and where spontaneous combustion may occur.
