Abstract: In order to further promote the development of open-pit coal mines with high quality and safety, increase the proportion of open-pit coal output, and enhance the overall level of safety production in China’s coal mines, the analysis of the development situation of open-pit coal mines with high quality and safety and the study of countermeasures are carried out, this paper analyzes the basic development situation of open-pit coal mines in China, puts forward the development trend of open-pit coal mining, and analyzes the short board and difficult problems influencing the safety development of open-pit coal mines, this paper proposes some countermeasures and suggestions for promoting the development of high-quality safety in open-pit coal mines from aspects of promoting the construction of green mines, rectifying and closing mines, formulating and revising standards, raising the level of equipment, building intelligent mines, improving the quality of personnel and standardizing the safety management of contractors, etc. The results show that the safety development of open-pit coal mines should strictly observe the two red lines of ecology and safety, standardize mining and stripping, loading, drilling and blasting, soil discharge, slope, reclamation, outsourcing and other production links, improve the overall level of technical equipment and safety management level, and strictly prevent the accident of death and injury in open-pit coal mines.
