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 ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Novel Coal Burst Criterion of Anchored Roadway Surrounding Rock under Dynamic Disturbance
Advances in Civil Engineering, 2023 Mining roadway is the main occurrence area of coal bursts in underground coal mining. A good understanding of the failure process of elastic zone and energy evolution inducing instability of support structure can offer useful insight into the coal burst ...

Study and practice on modification mechanism of engineering defects on impact coal and rock mass
Meikuang Anquan, 2022 Rock burst is one of the more serious dynamic disasters in coal mines. With the continuous increase of mining depth, rock burst disasters are becoming more and more serious. In view of the characteristics of major rock burst disasters, combined with the
