| 摘 要： | 在矿井通风业务实际计算中认为 :对于某特定巷道的摩擦阻力系数视为一定值 ,不考虑其随风流流向改变而改变。根据实际测量情况及流体力学基本理论 ,研究了摩擦阻力系数随巷道风流流向的改变而改变的现象 ,并用实测结果和流体力学理论对此进行定量分析和论证。 |
| 关 键 词： | 通风风向改变 摩擦阻力 摩擦阻力系数 |

| Abstract: | In daily mine ventilation work,we treat as airway friction resistance factor a constant.We don′t take into account the variance by airflow direction.This paper research the variance appearance of airway friction resistance by actual measuring and the theory of fluid mechanics,and proved by actual data and quantitative analysis. |
| Keywords: | variance of airflow direction friction resistance friction resistance factor |
