چکیده
|
Mines have a considerable role in polluting the environment. greenhouse gases and wastes mainly cause pollution. in this regard, trucks that carry ores in a mine are a primary source of these pollutants. selecting trucks with low fuel consumption can help to reduce pollution. the present research seeks to evaluate the effects of the objectives (cost objectives, production objectives, and environmental objectives) in mines on the type of trucks to select and the routes they take, as well as the effect of the duration of stone transportation on pollution. the study’s data were obtained from the chadormalu iron mine in yazd province. as the results showed, the objectives set in the mine affect the co2 level, and the goals followed with human health concerns induce lower co2 emissions. it found that the time ores are transported by trucks affects the co2 level. however, only the objective type affects the waste level resulting from tailings, not the speed of trucks. it is recommended that the duration of truck loading and unloading and the time the trucks waste waiting in lines be reduced to the extent possible to lower co2 emission.
