矿井通风系统是搞好矿山通风防尘的基础。是保护职工安全、健康和促进矿山生产发展的一项重要组织、技术措施。而影响矿井通风系统效果的因素又很多,特别是矿井风流的稳定性,是影响通风系统效果的决定性因素。风流稳定,经济效果就好。否则生产就无法进行。通风实践是检验系统效果的唯一标准。本人从事多年矿井通风的实际工作,对风流稳定性感触较深,因此,就从风流的稳定性谈通风系统的效果分析。一、角联网络是风流不稳定的根源 Mine ventilation system is to improve mine ventilation dust foundation. It is an important organization and technical measure to protect the safety and health of workers and to promote the development of mine production. However, there are many factors that affect the ventilation system of mine, especially the stability of mine ventilation, which is the decisive factor affecting the ventilation system. Stable, economic effect is good. Otherwise, production can not be done. Ventilation practice is the only test of system performance. I engaged in mine ventilation for many years of practical work, the deeper sense of the stability of the wind flow, therefore, from the stability of the wind ventilation system to talk about the effect of analysis. First, the corner network is the root cause of instability
