This has resulted in the potential for increased mining dust. Coal dust is not only harmful to workers but also make the risk of coal dust explosions in mine. Working conditions in underground mines are hard, hot and humid. The most toxic gas, especially mine dust, will increase to make occupational diseases, affecting the health of workers working in the mine. Mining dust is the cause of occupational diseases such as: lung dust, bronchial asthma, eyes, ears, nose and throat, affecting the health of workers and the quality of life of the community. Therefore, studying and developing a National Standard on dust control method by high-pressure ejector system in underground coal mining to reduce dust concentration in working areas to the allowable level according to the regulations of QCVN 01:2011/BCT. Therefore, in order to control the mine dust problem, it is necessary to develop a set of dust removal equipment suitable for underground coal mining. High-pressure water ejector system is selected to control dust in Quang Ninh mine.
