Due to the discharge of excessive pollutants,the environment of coal port is turning more and more serious.In order to improve the work condition of coal port,the research of handling technology for the coal port is made.Firstly,the process and formation mechanism of leakage and dust production equipment in the material transfer process are analysed.Then the cleaner production problems in each operating point are analysed and summarized.The improvement research is carried out in the working point of material handling,and the way to control the leakage and dust in the production process is also discussed.
