[0002] In recent years, my country's coal mining technology has developed rapidly, and its mining scale and depth have continued to increase. Due to the long-term dual effects of mine pressure and coal mine rock conditions on the underground working face, roof collapse of the working face often occurs, which has a significant impact on production safety. With continuous scientific and technological innovation, the underground roof support technology of coal mines has made great progress, and the probability of underground roof collapse accidents has dropped significantly, but it is still one of the main disasters in coal mines. Once a roof fall accident occurs, it will not only cause casualties to underground personnel, but also damage the coal mining working face. The collapsed stones and other debris will cause the roadway to be blocked, affecting the normal operation of the machine, causing certain losses to the economy, and causing considerable difficulties for subsequent development. If the roof fall accident is not handled properly, it will also lead to another roof fall collapse, causing more casualties and losses to personnel and the economy.
