Abstract

This paper reviewed the achievement of safety and efficient production in China coal mines. In 2019, the mortality per million tons was 0.083, the mechanization degree of coal mining in large coal mine enterprises reached 96.8%, and the productivity in whole China reached 1000 tons per year per capita. It summarized the main practices on safety and efficiency production in coal mines systematically, especially in scientific and technological progress, intensification layout, policy & regulation, and monitoring & early warning. The paper deeply analyzed main problems on safety and efficient production, such as: management concepts, complex multi-field coupling disasters, unbalanced development, professional talent shortage, and occupational health hazards. At last, the developmental countermeasures were proposed to raise the level of safety and efficiency production in detail.
