where ventilation may be required to cool the ambient temperature in a deep hot mine, however auto-compression must also be taken into account. As per CMR 153-2-(i)(2017), in every ventilating district not less than six cubic meters per minute of air per person employed in the district on the largest shift or not less than 2.5 cubic meters per minute of air per daily tons output whichever is larger, passes along the last ventilation connection in the district which means the inbye-most gallery in the district along which the air passes.

An auxiliary ventilation system takes air from the flow-through system and distributes it to the mine workings via temporarily mounted ventilation fans,

based on a wide variety of parameters. In most countries minimum requirements are outlined by law, regulation or standards. However, in some developing countries the mandated ventilation requirement may be insufficient, and the mining company may have to increase the ventilation flow, in particular

Sufficient volume of air is required for proper ventilation. A bulk of electric power is required for driving fans. By installing variable speed control air quantity can be optimized hence the power. At every place in the mine where persons are required to work or pass, the air should not contain
