Abstract: Roof disaster is an important hidden danger affecting the safe and efficient production of coal mines, and it has become
a high-incidence accident in coal mining in China, which seriously affects the sustainable mining of the working face. In order to
solve the problems of roof falling off, collapse and support difficulties in the top coal caving face, this paper first expounded the
characteristics and prevention and control technology of coal mine roof disasters, and then proposed solutions from the aspects of
working face support and roof management according to the actual engineering situation to effectively control the occurrence of
roof accidents in top coal caving face, and provide reference for the safe development of top coal caving operations in the same
type of coal mines.

Key words: coal mine; top coal caving; roof disaster; roof control
