On the Ventilation of Coal Mines [PDF]
Proceedings of the Yorkshire Geological SocietyI shall make no apology for the introduction of this subject before the Geological and Polytechnic Society, as it is certain that the person who would discover any safer modes of ventilation, or even any additional precautions to those now in use, and should succeed in having them generally adopted, would be for ever conferring a lasting benefit upon ...

ACMI: An index for exposed coal mapping using Landsat imagery [PDF]
arXivRemotely sensing the spatial distribution of exposed coal (EC) is significant for understanding the footprints of mining activities. However, widely applicable methods for the identification of EC surfaces remain inadequate because the choices of recent methods confront the diverse EC types and backgrounds.

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 793-807, December 2022., 2022 Monitoring and understanding the complexity and overall long‐term trends of the ecological consequences of multiple mining activities over large areas has been a challenge. Here, we propose a general framework for continuous monitoring of land use and vegetation dynamics in mine sites. We found that vegetation dynamics showed great heterogeneity across
