摘　　要：针对平煤九矿双风机联合运转通风系统存在的矿井通风总阻力偏大,己组回风段通风阻力所占比例偏高的现状,在对矿井通风阻力测量的基础上,构建平煤九矿的通风Ventsim三维可视化模型,采用数值模拟的方法,研究不同优化方案下矿井通风系统风流、风速等参数的动态演化规律,并对不同方案从通风效果和技术经济等方面进行比对分析。研究结果表明,通过扩修己二西翼回风下山、己组总回风和丁二回风下山等巷道断面,结合附近巷道断面确定巷道断面积为16 m2,有效降低了矿井的通风阻力。The total resistance of mine ventilation is relatively high and the ventilation resistance in the return airflow section accounts for a large proportion in the combined operation ventilation system of double fans in Pingmei No.9 Coal Mine.To deal with these issues,based on the measurement of mine ventilation resistance,a three-dimensional visualization model of the ventilation of Pingmei No.9 Coal Mine is constructed,by using the method of numerical simulation,the dynamic evolution law of parameters such as airflow and wind speed of mine ventilation system under different optimization schemes is studied,and the different schemes are compared and analyzed from the aspects of ventilation effect and technical economy.According to the research results,by expanding the roadway sections such as the ji-2 return air downhill of the west wing,the total return air of the group and the Ding-2 return air downhill,combined with the section of the nearby roadway,the cross-sectional area of the roadway is determined to be 16 m2,which effectively reduces the ventilation resistance of the mine.
