Experimental Study on Inhibiting the Gas and Coal Dust Explosion by Water Mist in Tube with Obstacle
Procedia Engineering, 2011 AbstractThe ordinary water mist has well affected on suppression and extinguishment flame, but the ability of physical extinguishment is influenced by the surrounding environment. The roadway in coal mine is very complex. So the related experiments need be considered.

SymmetryThe geometric symmetry of the pipeline constitutes a critical determinant in regulating the energy propagation dynamics during the explosion process. In the present study, a transparent plexiglass pipe experimental system incorporating a range of angles (30° to 150°) was meticulously constructed.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 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.
