摘要/Abstract

摘要： 为探究哈尔乌素露天煤矿采场风流分布特征,采用CFD数值模拟方法构建了哈尔乌素露天煤矿简易模型,模拟风向为南风、西北风、西南风,风速为3、5、7 m/s条件下的采场风流结构,探究不同风向风速对哈尔乌素露天煤矿坑内风流分布的影响。结果表明:哈尔乌素露天煤矿全年主要风向为南风、西北风及西南风,主要风级为二级、三级及四级;矿坑内部以直流风区域为主,环流区域集中在坑底—背风帮一侧;当风向来自排土场时,采场内部无显著环流;当风向来自端帮时,环流区域集中在背风帮一侧;随地表风速的增加,采场底部风速也在匀速增长,但其增长幅度并不大。

Abstract:

In order to explore the distribution characteristics of wind flow in stopes of Haerwusu Open-Pit Coal Mine, a simple model of Haerwusu Open-Pit Coal Mine was constructed by CFD numerical simulation method, and the wind flow structure in stopes was simulated under the conditions of south, northwest, and southwest winds at speeds of 3, 5, and 7 m/s. The influence of different wind directions and wind speeds on the wind flow distribution in Haerwusu Open-Pit Coal Mine was studied. The results show that south, northwest, and southwest winds are the main wind directions of the Haerwusu Open-Pit Coal Mine, and the main wind levels are Level 2, Level 3, and Level 4. The interior of the pit is dominated by the direct flow wind area, and the circulation area is concentrated on the bottom-leeward side of the pit. When the wind direction comes from the dump, there is no significant circulation in the stope. When the wind direction is from the end slope, the circulation area is concentrated on the leeward side. With the increase in surface wind speed, the wind speed at the bottom of the stope also increases at a uniform speed, but its amplitude is not large.

Key words: open-pit coal mine, wind flow in stope, numerical simulation, distribution characteristic, ventilation pattern
