Ventilation is an essential component of underground mining, as it helps maintain the safety and health of miners. Consequently production and work efficiency can be enhanced. The principal purpose of the ventilation system is to regulate the quantity and quality of fresh air while eliminating hazardous gases.

A three-dimensional model of the fan was developed based on the dimensions of the fan were estimated using a one-dimensional technique. A 3D model of an axial fan and a CFD analysis of its performance are investigated for underground mining ventilation application.

摘要

Ventilation is an essential component of underground mining, as it helps maintain the safety and health of miners. Consequently production and work efficiency can be enhanced. The principal purpose of the ventilation system is to regulate the quantity and quality of fresh air while eliminating hazardous gases. With the intention of increasing the energy efficacy of an axial flow fan, this study investigates the design aspects of mine ventilation fans. A three-dimensional model of the fan was developed based on the dimensions of the fan were estimated using a one-dimensional technique. A 3D model of an axial fan and a CFD analysis of its performance are investigated for underground mining ventilation application. Several cases have been studied, leading to the conclusion that the forced axial ventilation fan case, characterized by a Solidity value of 1.6, is deemed suitable for further investigation. The CFD analysis demonstrates that the forced axial flow mining fan has been designed to effectively discharge a volumetric flow rate of 47.13 m3/s of air, while operating at a rotational speed of 600 revolutions per minute. It achieves a significant static pressure rise of 838 Pascals across the rotor while consuming 48 kW of power.
