Land Reclamation Natural Revegetation of 15 Abandoned Mine Land Sites in West Virginia

Fifteen AML sites ranging in age from 13 to 35 yr in Northern West Virginia were selected from three surface-mined coal beds (Pittsburgh, Freeport, and Kittanning) to evaluate plant invasion and establishment on disturbed sites. Three 10 m by 10 m plots were randomly located on each site, and cover, density, and stem diameter of all woody plant species were measured. Herbaceous and plant litter...

Case study of controlled recirculation at a Wyoming trona mine.

Controlled recirculation has been used in the metal/nonmetal mining industry for energy savings when heating and cooling air, in undersea mining and for increasing airflow to mining areas. For safe and effective use of controlled district recirculation, adequate airflow to dilute contaminants must exist prior to implementation, ventilation circuit parameters must be accurately quantified, venti...

A Study on the Reclamation and Ecological Restoration in Subsidence Land in Chinese Coal Mine Area

Arbuscular mycorrhizal fungi (AMF) technology of bioremediation becomes one of the most hotspots in the research on coal-mining subsidence land. This article based on amorpha fruiticosa planting in the mining subsidence of Shendong mining area as a study object, arbuscular mycorrhizal fungi was vaccinated on amorpha fruiticosa after different monitor time, respectively measures are used to anal...
