Dust is produced in the quarrying process while it is being blasted, crushed, screened, transported and stored. There are three ways that you can manage dust: 1. Contain it, 2. collect it, or. 3. suppress it. The Pareto principle (or 80-20 rule) applies to quarry dust generation. "Eighty percent of the dust in a given quarry is generated by 20%

Power []. The Quarry must be powered by one or more engines. Quarries have an internal buffer of energy, and require a few seconds to charge. Approximately 9MJ/t is enough to keep a quarry continuously running (without pausing between actions), but a quarry will use up to 32MJ/t at maximum speed (increased from 9MJ/t previously).
