As the workings of underground mine is getting deeper, the working environment is getting worse. Accordingly, it is required to improve underground ventilation system by the precise data acquisition and computer simulation technology. This study is aimed to apply the new technology to mine sites and improve the underground working environment. This study has been carried out at S colliery. For providing improvement program of underground ventilation of the mine, various fundamental data such as number and elevation of each nodes, length, section area, perimeter of airways and their resistance are surveyed respectively. According to the above data, optimum ventilation programs have been suggested after a series of computer simulation process.
