Particle flow numerical simulation model for coal and gas outburst and its microscopic outburst mechanism description. [PDF]
Sci Rep, 2023 Abstract The finite difference model and particle flow model were constructed to reproduce the process of coal and gas outburst in front of the tunnel. The reliability of the particle flow model was verified by studying the internal stress, gas pressure, and related parameters of gas and coal two-phase flow.

Coal and gas outburst prediction based on data augmentation and neuroevolution. [PDF]
PLoS OneCoal and gas outburst (CGO) is a complicated natural disaster in underground coal mine production. In constructing smart mines, predicting CGO risks efficiently and accurately is necessary. This paper proposes a CGO risk prediction method based on data augmentation and a neuroevolution algorithm, denoted as ANEAT.

Research on Temperature Variation during Coal and Gas Outbursts: Implications for Outburst Prediction in Coal Mines [PDF]
Sensors, 2020 Coal and gas outbursts are among the most severe disasters threatening the safety of coal mines around the world. They are dynamic phenomena characterized by large quantities of coal and gas ejected from working faces within a short time. Numerous researchers have conducted studies on outburst prediction, and a variety of indices have been developed to
