Effect of Coal Particle Breakage on Gas Desorption Rate during Coal and Gas Outburst

open access: yesApplied Sciences
The gas contained in coal plays a crucial role in triggering coal and gas outbursts. During an outburst, a large quantity of gas originally absorbed by coal is released from pulverized coal.

Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 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.
