Evaluating the risk of coal bursts in underground coal mines
International Journal of Mining Science and Technology, 2016 Abstract Coal bursts involve the sudden, violent ejection of coal or rock into the mine workings. They are almost always accompanied by a loud noise, like an explosion, and ground vibration. Bursts are a particular hazard for miners because they typically occur without warning.

A coal burst model based on roof vibration and coal slippage
IOP Conference Series: Earth and Environmental Science, 2020 Abstract Rock burst poses a serious threat to mining, and its mechanism still needs to be studied. Statistics show that more than 85% of rock bursts occur in mining roadways. The authors investigated the mechanism of rock burst in the roadways by creating a finite elastic long beam dynamic model in longwall mining based on the elastic ...
