Background

China is one of the strong countries of coal resources, the number of coal miners is the largest globally, and the underground operation of coal mines is a special work in the environment. Due to the influence of geological environment, most coal mine sites have poor operation conditions, are dark and wet, have narrow working surfaces, and are threatened at any moment along with disasters such as gas, coal dust, water, fire, roofs and the like. Therefore, in order to guarantee the life safety of coal mine workers, the use of protective articles for effectively preventing occupational hazards is very important.

The rock burst refers to the dynamic phenomenon of sudden and violent damage of coal (rock) bodies around a coal mine roadway or a working face due to the instantaneous release of elastic deformation energy. When rock burst occurs, coal rock blocks are often thrown out, mine support materials are broken and popped out, and once the thrown coal rock blocks hit a human body, the thrown coal rock blocks cause great damage to personnel.

In recent years, with the increase of coal mining depth in China, the problem of rock burst is more and more prominent, and the occurrence of rock burst seriously threatens the personal safety of coal mine workers.
