Abstract In order to solve the problems of excessively long ventilation lines, complicated systems, and large ventilation resistance, the ventilation parameters of the original mine ventilation system was studied and analyzed in Xuehugou Mine, and a ventilation optimization plan through the layout of new air return inclined shafts was proposed. The advanced software Ventism three-dimensional decision-making and simulation software simulates and analyzes the optimized ventilation system. It was found that the software can quickly obtain the wind network settlement, the demand of wind flow and the dynamic simulation of the wind flow. The technology provided basis and reference for decision-makers and the economic safety.
