According to the roles of mining fractures development and relief gas flow, a novel method for the comprehensive gas drainage was proposed and engineering practiced in the mining field, which includes long drilling boreholes, oblique crossed boreholes and upper corner flexible drainage pipelines.
This work provides a model that combines system dynamics with comprehensive assessment for drainage enterprise sustainability evaluation and identification of the most significant factors.
For further enhancing foam drainage and comprehensive knowledge of the spiral internal component (SIC), the effects of its thread pitch and inclined angle were experimentally and theoretically investigated.
A comprehensive hydrological modeling study in the drainage area of a hydropower reservoir in central Switzerland is presented.
We considered for analysis all patients from Northwestern University's Prentice Women's Hospital and affiliated Lynn Sage Comprehensive Breast Center with wound, fluid, drainage, or breast milk cultures positive for S. aureus from January 1998 through December 2005.
We sequenced 120 individuals from 53 drainages to provide a comprehensive geographic picture of Central American Rhamdia systematics and phylogeography.
In addition to the efforts aimed at making agriculture and forestry more competitive through a comprehensive reallocation process, improvement of road and drainage networks, landscaping, environmental management, conservation projects, and other functions may be implemented in land consolidation.
Integrated extraction of coal and gas was implemented in 2011, with comprehensive gas-control measures, such as protective mining, progressive drainage, Y-type ventilation, expansion of the gas extraction system, underground gas drainage from retained roadways, surface well drainage, and gas use.
Reactive transport modeling of a permeable reactive barrier for the treatment of mine drainage was used to integrate a comprehensive data set including pore water chemistry and solid phase data from several sampling events over a >3-year time period.
The used approaches in this study include a comprehensive morphometric analysis that can be applied for any drainage system elsewhere.
