An improved void-resistance model for abandoned coal mine gas reservoirs [PDF]

International Journal of Coal Geology, 2016
Previous studies have shown that the gas pressure behaviour of some abandoned coal mines may be described with the aid of a simple conceptual model, the so called void-resistance model.

Utilization of resources in abandoned coal mines for carbon neutrality

Science of The Total Environment, 2022
Under the new vista of carbon neutrality, all industries in China face new challenges. As the pillar industry for fossil energy, the coal industry cannot blindly "de-coal". It is necessary to combine the two-way force associated with abandoned mines to turn energy into resources and problems into solutions.

Substantial Methane Emissions from Abandoned Coal Mines in China

SSRN Electronic Journal, 2022
China has shut down and abandoned a substantial number of coal mines since 1999, which have been releasing methane (CH4) for many years. However, the characteristics of China's abandoned mine methane (AMM) emissions are still unclear; this is a concerning knowledge gap because coal mines are the largest contributor to China's anthropogenic CH4 ...

Fires in Abandoned Coal Mines

Environmental & Engineering Geoscience, 1990
Mine fires occur on abandoned mine lands throughout the U. S. coal fields. They threaten the health and safety of the local populations and consume a non-renewable natural resource. In general, mine fires are the most costly abandoned mine lands problem to mitigate. In active mines, fires are quickly extinguished by the mining company as they present a

Land Reclamation at Abandoned Deep Coal Mine

Journal of the Environmental Engineering Division, 1979
A typical abandoned midwestern deep coal mine site was selected, final land use determined, baseline environmental data collected, engineering plans developed and implemented, and a post- construction evaluation begun. The project is a cooperative effort by two state agencies — the Abandoned Mined Land Reclamation Council of Illinois and the Illinois ...

An overview on flooding induced uplift for abandoned coal mines

International Journal of Rock Mechanics and Mining Sciences, 2021
Abstract Flooding induced uplift for abandoned coal mines is monitored mainly by satellite data and geodetic levelling. Predictions are based on empirical formulas, but nowadays numerical simulation procedures provide an interesting alternative, because it is physically based and allows to consider complex mining, geological and hydrological ...
