Abstract: Underground mines are a highrisk industry,and rooffaulting accidents are one of the most frequent and dangerous accidents in underground mines.Through a lot of research,Yuxi Dahongshan Mining Co.,Ltd.invented a special white antisolid coating for underground mine tunnels,and sprayed white antisolid coatings on the tunnels with a special construction technique.When the roadway has hidden dangers such as roof fall,it will show extremely obvious black burr cracks on the white coating,making the hidden danger source of roof fall in underground mines visible.This method not only effectively highlights the hidden safety hazards of roof fall in underground mine roadways,but also provides a convenient,intuitive and economical new method for underground mine ground pressure monitoring.At the same time,the process technology greatly improves the underground mine roadway environment.It has great promotion and application value.

Key words: underground mine,surrounding rock collapse,visualization of hidden hazards,environment reconstruction of underground mine
