摘　　要：复杂地质条件下的矿井通风系统对矿井安全生产具有至关重要的作用。通过对四台矿东一采区103工作面中瓦斯含量、瓦斯涌出量和二氧化碳涌出量等参数进行分析,提出两种巷道掘进时通风技术方案,并对两种方案进行理论和实践分析。分析结果证明,方案二通风效果较好,全负压通风中风流瓦斯浓度小于0.05%,排放巷风机吸风口处的瓦斯浓度小于0.22%,运输顺槽风机吸风口处的瓦斯浓度小于0.32%,满足复杂地质条件掘进巷道通风要求。Mine ventilation system under complex geological conditions plays a vital role in mine safety production.Based ON THE ANALYSIS OF GAS CONTENT,gas emission and carbon dioxide emission IN 103 WORKING face of East No.1 mining area of Sitai Mine,two kinds of ventilation technology schemes during roadway excavation are put forward,and the two schemes are analyzed theoretically and in practice.The analysis results show that the ventilation effect of Scheme 2 is better.The gas concentration in the air flow is less than 0.05%in the total negative pressure ventilation,the gas concentration in the air intake outlet of the fan in the discharge lane is less than 0.22%,and the gas concentration in the air intake outlet of the fan in the transport route is less than 0.32%,which meets the ventilation requirements of the tunneling roadway under complex geological conditions.
