An abandoned gypsum mine has been discovered beneath the route of a highway construction in Hunan province, south China. Due to the highway construction and operations safety, there is an urgent need for a comprehensive stability analysis of the abandoned mining area. The 3D laser scanning detection technique has been adopted, …
Downloadable! Gypsum mines in China are mostly exploited through room and pillar mining. Due to backward mining technology and a long history of mining, a great number of pillars were left in gypsum mines. Many serious work safety accidents occurred as the result of goaf instability in history, which posed severe threats to the security of people's …
Flue gas desulfurization gypsum (FGDG) is a by-product generated in the combustion of coal. This solid residue has the potential to be applied to the soil and help to reduce acidity and provide nutrients to soils impacted by surface coal mining. Thus, the objective of this work was to evaluate nutrients and heavy metals in soil and plant tissue …
