摘　　要：China is rich in coal resources and has a complete range of coal types, ranking first in the world in coal reserves. Due to the complex occurrence of coal resources in China, large-scale mines coexist with small and medium-sized mines, and the coal mining technology is different. With the continuous improvement of mechanized mining, the development of comprehensive mechanized coal mining technology has been promoted. According to the coalfield geology and the distribution of coal seams, this paper studies the application of fully mechanized top-coal caving mining technology in the three soft and unstable coal seams in small coal mines. It has very important reference significance for the popularization and application of fully mechanized top-coal caving mining technology in small coal mines to improve the safety of coal resources mining in small coal mines and reduce coal mining accidents.
