soil characteristics and microbial community response inmay 30, · the microbial community and functional flora in rare earth mining areas are correlated, but the characteristics and metabolic pathways of pollutant in such mining areas are still poorly known. the heavy metals, rare earth elements, and microorganisms present after mining of rare earth mine sites were analyzed. after mining, all sampling sites exhibited low ph and low total organic carbona study of first moments in underground mine emergencymine emergency plans are mandated in the u.s. mining industry at the federal level. all miners should be trained to understand and follow the mine emergency plan where they work. some companies see emergency response planning as developing a written response plan that can be pulled from the shelf and used to manage an emergency when it occurs.response of bacterial communities to mining activity innov 26, · up to10%cash back· most studies to date have focused on low altitude mining areas, but the pollution issues and response of soil microorganisms to such issues may be more intense in alpine areas because of seasonal freezethawing, which results in heavy metal leaching, higher availability of substrate, and higher microbial activity (sharma et al. 06).author chengyu yuan, fayong li, ziqiang yuan, guoyu li, xinqiang liangsurface mining and reclamation effects on flood responseapr 07, 09· our goal was to investigate the flood response of the 7km 2 georges creek watershed as a function of increased surface mining and subsequent reclamation. flood response was evaluated at the daily time step due to unavailability of hourly data for this and many other watersheds in the cap.ground response and mininginduced stress in longwallmar 27, · in order to improve ground control of the longwall mining, ground response and mininginduced stress in the longwall panel of a kilometerdeep coal mine are investigated in this study. field measurements on abutment stress, roof displacement, and fracture development indicate that the region influenced by the longwall mining reaches 0 m ahead of the longwall face.the response of soil bacterial communities to miningdec 01, · coal mining subsidence can trigger a series of ecological and environmental problems, such as desertification, vegetation degeneration and natural resource degradation, which maycited by 29the impact of sustainability reporting determined from theup to10%cash back· jul 23, · heenetigala k., armstrong a. the impact of sustainability reporting determined from the response of mining corporations to environmental risk. in eweje g., bathurst r.
