Estimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology
Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been...
متن کاملAssessment of health risks to skin and lung of elevated radon levels in abandoned mines.
Radon, together with its progeny, is present in high levels in some underground sites. Radon is known to increase the risk of lung cancer, while increased levels of radon decay products on the skin surface have been implicated in skin cancer induction and at sufficient levels might cause deterministic effects such as erythema. Although radon levels in working mines are controlled, radon in aban...
متن کاملAbandoned Uranium Mines Project Atlas Project Overview
The Navajo Nation is located on the Colorado Plateau and encompasses over 25,000 square miles across Arizona, New Mexico, and Utah. The distinctive physiography of this region has resulted in a major mining area for uranium. The Navajo Nation includes intensely dissected rocky regions and has elevations that range from about 3,000 feet to slightly over 10,000 feet. The region is known for a wid...
متن کاملThe earth's open wounds: abandoned and orphaned mines.
Objective. This study was performed to review the clinical utility of commercial laboratory Toxoplasmosis-specific IgM testing during pregnancy and outcomes of the gestation at our institution. Methods. A retrospective review of all women referred for suspected acute Toxoplasma gondii infection during pregnancy from 1984 through 2004 was performed. Women were diagnosed with suspected acute toxo...
متن کاملGas Drainage Improvement in Underground Coal Mines
Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...
