Simulation of coal and gas outbursts in outburst-prone zones of coal seam
The problem of mining safety in outburst-prone coal seams has not yet been ful-ly studied and resolved, so research related to outbursts continues to be relevant for many coal-mining countries. The purpose of this work is to study the coupled pro-cesses of elastoplastic deformation of a coal seam, methane filtration and desorption, which occur in the ...Viktoriia Krukovska +1 more

The role of coal strength in coal and gas outbursts
Physics of FluidsCoal strength is one of essential factor influencing the occurrence of coal and gas outbursts (CGOs). In order to explore the laws of CGOs, simulation tests with different coal strengths were carried out under a self-developed CGO device. The results show that as the coal strength increases, the relative outburst strength decreases.

A mechanism of outbursts of coal and gas
Mining Science and Technology, 1984Abstract Rock and gas pressures combine to cause outbursts of coal and gas. The actions and interactions of geological factors, mining factors and intermediary events during the phenomenon are described.

Role of Tectonic Coal in Coal and Gas Outburst Behavior During Coal Mining
Rock Mechanics and Rock Engineering, 2019Coal and gas outbursts are small-scale geological disasters controlled by tectonic movement, and tectonic coal is widespread in outburst zones. In this study, we compare tectonic and intact coal specimens to examine the basic properties of tectonic coal.
