摘　　要：At present, the hazards of coal mine dust have been listed as one of the five major hazards in mines. With the continuous development of China's coal mine industry, the scale of coal mining is also increasing. A large number of machines produce a large amount of coal mine dust in roadway comprehensive excavation and coal mining, which results in workers being vulnerable to the hazards of coal mine dust in the production process. It not only affects the health of the body, but also brings hidden dangers to the safe production of mines. The treatment of coal mine dust has always been an important problem in the mining process. Based on personal practical production experience, this paper discusses the research on eliminating coal mine dust and improving mine working environment in fully mechanized and fully mechanized mining face with two-phase foam in the hope of making some contribution to protecting the safety and health of miners and the environment on which human beings depend for survival.
