柴油机运输设备(如自动斗车、自卸卡车等等),由于具有机动灵活性和生产效率高等优点,在地下工程大断面巷道掘进中,得到越来越广泛的应用。但是,柴油设备工作时要排放出大量的有毒气体,如一氧化碳、氮氧化物、二氧化硫、醛类、致癌物质等有害成份,造成巷道内的空气严重污染。即使没有净化装置,有 Diesel engine transport equipment (such as automatic dump trucks, dump trucks, etc.), due to the advantages of mobility and high production efficiency, are gaining more and more widespread application in tunneling of large sections of underground engineering. However, diesel equipment emits a large amount of toxic gases such as carbon monoxide, nitrogen oxides, sulfur dioxide, aldehydes, carcinogens and other harmful substances while working, resulting in serious air pollution in the roadway. Even without purification equipment, there
