摘要:

自然风压作为一种客观存在的自然现象,其受气候、季节温度等影响较大,难以控制,是影响矿山通风系统不可控的因素之一。为克服自然风压对通风系统的影响,此次通过对自然风压的形成机理及影响因素进行分析,推演出计算自然风压的方法。研究以此为基础,以某受自然风压影响的平硐开拓矿山为实例对象,通过检测、分析、计算自然风压对该矿山的影响,并给出相关优化技术措施,解决了该矿山受自然风压影响,各主平硐季节性风向变化的问题。

Abstract:

As an objective natural phenomenon greatly affected by climate,seasonal temperature and so on,natural air pressure is difficult to control and is one of the uncontrollable factors that affect the mine ventilation system.To overcome the effect of natural air pressure on the ventilation system,the method of calculating natural air pressure is deduced by analyzing the principles and influencing factors of natural air pressure formation.Based on this study,a case study of a mine with adit development influenced by natural air pressure is used to calculate the impact of natural air pressure on the mine by example detection analysis,and related optimized technical measures are made,in order to solve the problem that the mine is affected by natural air pressure and seasonal wind direction change in each main adit.
