Research on Medium term Ventilation System Planning of Dayingezhuang Gold Mine Based on Ventsim
Due to the impact of efficient mining speed and deep resource conditions,the Dayingezhuang Gold Mine requires timely mid-term ventilation system planning to meet the needs of deep production.Based on the air volume calculation and distribution of the mid-term ventilation system,an optimization plan for the ventilation route was developed.A three-dimensional model of the ventilation system for the optimization plan was established using Ventsim software,and the ventilation resistance during easy and difficult ventilation periods was calculated.At the same time,the selection of the-676m mid section main fan was carried out through simulation software,and the operating conditions parameters of the main fan were determined.After completing all optimization schemes,the operation of the overall ventilation system was analyzed in the 3D ventilation model.The simulated air volume of the main shaft inlet and return air shafts was basically consistent with the designed air volume,and the wind speed of the main shafts met the requirements of safety regulations.By estimating the engineering quantity and analyzing other investment estimates for the optimized plan,it is convenient for the mine to arrange and implement the planning plan reasonably.
