摘要
本文通过实验的方法,考察了在不同的外部条件(冒高处巷道风速高低,冒高前巷道有无变坡)下,冒高内的蓄热与供氧条件。实验表明,冒高内蓄热与供氧条件相互关联,二者均受外部条件的影响,且外部条件对其影响程度依次为:巷道风速>巷道几何条件>二者的交互作用。
By means of experiment,this paper studied the conditions of storage of heat and supply of oxygen under different external conditions(rate of air—flow and slope of the road in front of the caving zone).The experiments show that the condi- tion of storage of heat is correlative with the condition of the supply of oxygen,both the storage of heat and the supply of oxygen in caving zone are influenced by the external conditions of which the rate of air—flow has the most significant effect,and the slope has more significant effect than the interaction of the flow rate and the slope.
