pollution control technical manual fortosco ii oil shale

Production-scale mining of the oil shale will be accomplished by conventional underground room-and- pillar mining. Initial excavation will begin from a portal bench constructed in the upper section of the Middle Fork Canyon, at an elevation of about 7,000 feet, at which point the Mahogany oil shale zone outcrops on opposite sides of the canyon

design guidelines : underhand cut and fillcemented paste

Difficult ground conditions negatively affect both mine production and the safety of underground workers. Underhand cut-and-fill mining is a potential solution to these issues. Discussions with mine sites revealed the use of sill beams in underhand cut-and-fill mining is not optimized. Optimization in ground support, development of in-situ strength test, and revisions of design standards are

dieselengine exhaust: basis for occupational exposure

Occupational exposure occurs in mining, construction work, professional driving, agriculture, and other activities that apply diesel-powered vehicles and tools. The highest exposures have been detected in underground mines and tunnel construction sites, ie, enclosed worksites that use heavy diesel equipment (Coble et al., 2010; Pronk et al., 2009)
