Abstract There are thousands of abandoned mine land (AML) sites in the U.S. that need to be restored reduce wind and water erosion, provide wildlife forage, shade streams, improve productivity. Biochar created from woody biomass would normally burned slash piles can applied soil properties is one method restore AML productive capacity. Using this ‘waste’ for biochar reclamation activities will ...
This paper evaluates the application of accumulative chamber for finding gas flow relations from abandoned mine through rock environment. It was proved that only in a few cases minimum values of volume flow are registered. This demonstrates that the escape of gas only occurs in the areas with suitable communication. Abstrakt V předloženém článku se posuzuje aplikace akumulační komory ke zjištěn...
Microorganism-derived polyene polyketides have been shown to display a variety of biological activities and have attracted great interest due to their structurally intriguing chemical diversity. Two new polyenes were isolated from a culture broth of Streptomyces sp. KMC-002 obtained from a soil sample in an abandoned mine. The structures of these compounds were determined to be α-pyrone-contain...
Mine drainage waters vary considerably in the range and concentration of heavy metals they contain. Besides iron, manganese is frequently present at elevated concentrations in waters draining both coal and metal mines. Passive treatment systems (aerobic wetlands and compost bioreactors) are designed to remove iron by biologically induced oxidation/precipitation. Manganese, however, is problemat...
Asbestos is a commercial term that represents several different silicate minerals which separate into long thin fibers. Asbestos has been used in numerous commercial applications due to its outstanding incombustible and insulating characteristics but causes fatal diseases such as lung cancer, asbestosis and malignant mesothelioma so strict regulations and controls for asbestos bearing rocks and...
