摘　　要：采用矿井受限空间多重尘源粉尘模拟平台,结合数值模拟与相似实验的方法,研究了负压通风条件下不同位置及不同抽风量对粉尘质量浓度的影响。结果表明:抽风量显著影响粉尘质量浓度。模拟结果与实验数据相吻合,验证了模拟的可靠性,为液压支架移架产尘通风措施的优化提供了科学依据。The impact of different positions and exhaust volumes on dust mass concentration under negative pressure ventilation conditions was studied using a multi source dust simulation platform in confined mine spaces,combined with numerical simulation and similar experiments.The results indicate that the exhaust volume significantly affects the quality concentration of dust.The simulation results are consistent with the experimental data,verifying the reliability of the simulation and providing a scientific basis for the optimization of dust ventilation measures for hydraulic support relocation.
