Sommaire: PAH compounds have been found in the exhaust from all types of engines burning hydrocarbon fuels. They have also been found in the air over cities and in water. The authors report on a study to assess the concentrations of twelve different PAH compounds in several different environments in dieselized underground mines. In addition, the differences in the PAH levels and distributions in different mines will be demonstrated. Finally, the influence of blasting and the type of diesel engine used...

Sommaire: The use of current electronic technology in the design of new underground mine communications equipment is providing improved and expanded voice communications which can, in turn, contribute to improved productivity and safety. A review of equipment that is now available or under development includes the following categories: WIRED SYSTEMS—1. Pager phones with selective calling, audible and visual alerting and message indicator.2. Multi-conversation pager phones that use multiwire cable...

Sommaire: A field laboratory for use in monitoring underground mine air quality has been developed and proven in underground service. The laboratory includes two separate monitoring systems and data analysis computer programs. One is the Mine Air Monitoring Laboratory (MAML). This is an enclosed trailer-mounted laboratory capable of monitoring CO2, CO, NO, NO2, particulate matter, SO2, NH3, temperature and air velocity in the mine drift. The MAML can be up to 1000 feet away from the area being...

Sommaire: The operations of a large-scale open-cut mine are simulated to produce a user-oriented interactive digital model. SIMULA is chosen as the programming language and a sophisticated data base system is designed to consider the complex information network of large mines. The main features of the program are the mine planning and mine evaluation modules. These modules are responsible for the computation of truck-shovel performance and other equipment details in a mine. Stochastic methods are...

Sommaire: Grinding mill hydrostatic trunnion bearings require an external pumping source to provide and maintain the oil film between the bearing members. In order to guarantee a predetermined minimum film thickness, the lubrication system tends to be oversized. The oil film is "indirectly" controlled by flow, pressure and temperature monitors with fixed settings on the conservative side. This can lead to excessive maintenance and abbreviated life for the lubrication system components. A...

Sommaire: Continued and expanded use of underground diesel-powered equipment is considered desirable in order to achieve necessary production capability, particularly when coal becomes increasingly in demand as an energy source. Although diesel engines are derated for underground use, concern has been expressed in many quarters regarding the health effects of worker exposure to diesel-generatedpaniculate and NOx emissions. This concern will increase as Canadian diesel fuel quality becomes heavier and...

Sommaire: The toxicity reduction of emissions from two diesel engines by the emulsification of water into fuel oil was investigated to determine the applicability of such systems to underground mining machinery. The engines studied were: 1) the Deutz F6L714, four-stroke, air-cooled, 6-cyUnder, V-configuration, indirect-injection (IDI) engine, and 2) the Detroit Deisel Allison Division 8V71N, two-stroke, water-cooled, 8-cyUnder, V-configuration, direct-injection (DI) engine.The application of emulsified...

Sommaire: Plant owners and operators, plant designers and grinding mill manufacturers are giving much attention to the design and manufacture of autogenous and semi-autogenous grinding mills, particularly the mills that have large diameters and draw power up to 10,000 hp and greater. Reliable designs giving long operating lives are required in today's ore processing plants.This paper reviews bench-scale and pilot-plant testing to determine first if the ore is suitable to be ground by these methods and...
