一、意义 采场包括老采空区和生产采面两个部分流场。生产采面流场是由生产采面及相连的采空区组成。 由于采场空间,采场的宽度(或直径)与长度之比,都和管道或巷道相差悬殊,所以用管道流体理论,不如用流体力学中的流场理论分析,研究采场气体流动更为合适。 采场是矿井的组成部分,是矿井生产活动的重要场所,采场气体流动状态,直接影响矿井的原煤生产和井下的人身安全。 流场理论包括的内容很广泛,我们只能用流场的基本概念和与采场相类似的那部分基本理论来分析、研究采场气体流动问题。 二、不可压无旋流场函数及基本方程
First, the meaning of Stope Including the old goaf and production of two-part flow field. The production flow field is composed of the production face and the connected goaf. Due to the stope space, the ratio of the width (or diameter) to the length of the stope is quite different from the pipe or roadway. Therefore, using the theory of pipe fluid, it is better to analyze the flow field in fluid mechanics than to study the flow of gas in the stope. Suitable. The stope is an integral part of the mine and is an important place for the production activities of the mine. The flow of gas in the stope can directly affect the coal production in the mine and the personal safety in the mine. Flow field theory includes a wide range of content, we can only use the basic concepts of flow field and stope that similar to that part of the basic theory to analyze and study gas flow in stope. Second, the non-compressible non-cyclone field function and the basic equation
