Abstract

In order to solve the problem of dust pollution in open-pit coal mine, this paper studies the characteristics and prevention measures of dust pollution in open-pit coal mine. Firstly, the effects of different phosphorus treatments on pH value and water-soluble phosphorus of dust polluted soil in open-pit coal mine, the effects of different phosphorus treatments on water-soluble lead and zinc, and the effects of different phosphorus treatments on the contents of exchangeable lead and zinc in dust polluted soil were analyzed. On this basis, multi-directional dust pollution control measures with public participation in construction dust supervision and control as the core are put forward. The test results show that after comprehensive treatment, the amount of dust is reduced, and the phosphorus containing substances can repair the polluted soil of open-pit coal mine, and a good soil remediation effect is achieved.
