中文摘要：
为改善井下作业环境、提高矿井防灾能力，基于Ventsim软件对井下作业环境中产生的污染物进行定量计算机模拟。研究表明：污染物模拟线路与井下污染物实际扩散线路基本一致。对机械化程度高、井下空气污染严重矿井的灾害预警和安全生产起到了指导意义，有利于改善井下工人的作业环境。
英文摘要：
To improve the underground working environment and the ability of mine disaster prevention, the pollutants in the under- ground work environment were simulated quantitatively based on Ventsim software in the computer simulation. Results show that：Pollu- tant analog line was basically the same as the actual pollutant diffusion lines underground. It has guiding significance to disaster warning and production safety of coal mines of high mechanization degree, serious air pollution, and is helpful for improving the underground working environment of workers.
