当联合掘进机作业肘,伴随着被掘下来的大量破碎岩石,在掘进工作面的空气中会有大量粉尘飞扬。在机械化掘进工作面缺少火尘手段的情况下,空气含尘量为800mg/m~3,随着采矿工程的延深,在有可能提高联合掘进机的动力装备程度及准备巷道掘进速度时,应当进一步提高空气含尘量原有水平。 目前,都知道,在准备巷道掘进施工过程中,采用综合防尘系统,就可以保证掘进工劳动时不受粉尘危害。该除尘系统包括专
When combined with TBM operation elbow, accompanied by a large number of broken rock was dug, there will be a lot of dust flying in the air heading face. In the case of mechanized excavation face lack of fire means, the air dust content of 800mg / m ~ 3, with the deepening of mining engineering, it is possible to improve the degree of power equipment and TBM roadway heading speed, The original level of air dust content should be further improved. At present, we all know that in the preparation of roadway excavation construction process, the use of integrated dust control system, we can ensure that the excavator work from dust hazards. The dust removal system includes a dedicated
