摘要
在现有通风系统的基础上,结合实际条件,分析3种通风调整方案的优劣点,最终确定全风压与局部通风机相结合的通风方式。实践表明,该项长距离局部通风技术保证了巷道掘进所需的风量,杜绝了掘进工作面瓦斯的积聚和超限现象,实现了长距离巷道的安全掘进。
Combined with the actual conditions, analysis of the pros and cons of three ventilation modes using points, eventually determine the wind pressure and the combination of local fan ventilation.Practice shows that the local ventilation technology that ensures the long distance drivage required air flow, and to eliminate the phenomenon of gas accumulation and overrun of tunneling faces, has realized the long-distance tunneling roadway safety.
