Excessive water inflow in a mine poses great threat to its operation, especially the case of salt mine. In 1992, rapid outflow occurred Mina traverse Wieliczka Salt Mine, and number investigations were undertaken assess causes condition rock mass, including gravity microgravity surveys discussed this paper. The first these was investigate mass with respect geological, hydrogeological properties...
Stalactites (CaCO3 and salt) from water seeps are frequently encountered in ceilings of mine tunnels whenever they intersect water-bearing faults or fractures. To determine whether stalactites could be mineralized traps for indigenous fracture water microorganisms, we analyzed stalactites collected from three different mines ranging in depth from 1.3 to 3.1 km. During sampling in Beatrix gold m...
Stream water quality in areas of the western United States continues to be degraded by acid mine drainage (AMD), a legacy of hard-rock mining. The Rico-Argentine Mine in southwestern Colorado consists of complex multiple-level mine workings connected to a drainage tunnel discharging AMD to passive treatment ponds that discharge to the Dolores River. The mine workings are excavated into the hill...
OBJECTIVE Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of tailings and metal contamin...
The use of gypsiferous mine water for irrigation of agricultural crops is a promising technology that could solve problems related to both shortage of irrigation water and disposal of effluent mine drainage. The long-term effect of irrigation with lime-treated acid mine drainage on soil properties and catchment salt load was investigated. The soil water–salt balance-crop growth model (SWB) and ...
One of the factors which can kill or decrease the viability of bioleaching bacteria is the creation of toxicity due to the process of metal release from mine stone. This toxicity is partly due to the presence of arsenic in mine stone. In the present study mutagenesis method was used to improve the bioleaching process performance by using UV and gamma rays. The influence of radiations (UV& gamma...
The complete genome sequence of Staphylococcus succinus 14BME20, isolated from a Korean fermented soybean food and selected as a possible starter culture candidate, was determined. Comparative genome analysis with S. succinus CSM-77 from a Triassic salt mine revealed the presence of strain-specific genes for lipid degradation in strain 14BME20.
