地下开采中,排除爆破和发动机产生的有毒气体,并供给新鲜空气是一个十分困难的问题。特别是在贯穿通风不易到达的工作面,如某些平巷掘进、隧道掘进以及分段崩落法采用装载机装载时,这些问题更加困难和费钱。如果采用风动或电动设备,对通风的主要要求是排除爆破有毒气体和粉尘。近年来,柴油设备普遍使用。柴油机到达的所有工作面都要求有效的通风。
In underground mining, it is a very difficult issue to exclude the toxic gases from blasting and engines and to supply fresh air. These problems are more difficult and more costly, especially for work surfaces that are not easily reached through ventilation, such as the loading of loaders, tunneling and sub-caving methods with loaders. If pneumatic or electric equipment is used, the main requirement for ventilation is to exclude explosive gas and dust. In recent years, diesel equipment commonly used. All facets where diesel engines reach require efficient ventilation.
