The Effect of Different Regulations In Various Parts of the World on the Design and Certification of Diesel Equipment for Underground Coal Mines

Abstract This paper discusses how design differences in FLP diesel equipment in underground coal mines came about. "Design standards" tend to create differences between countries while fostering uniformity among products of competing manufacturers. "Performance requirements," on the other hand, tend to eliminate differences between countries while encouraging competitive development of better products. Examples of regulations from the U.S., Canada, Great Britain, Australia, South Africa, etc., are used to illustrate differences in the design and certification of diesel equipment for underground coal mines.
Keywords: Coal mining, Underground mining, Diesel equipment, Equipment standards, Regulations.

Summary: The production of low- and medium-Btu gas from coal provides a more economic source of energy for most industrial users than pipeline-quality coal gas (SNG), although the latter has received more publicity. The paper reviews existing and advanced methods of coal gasification, with particular emphasis on the production of low- and medium-Btu gas for industrial and utility use. Some of the ways in which coal gasification can be integrated into power cycles and industrial plant energy balances...

Summary: Kaiser Resources Ltd. owns and operates a 5-million-ton-per-year open-pit and hydraulic coal mine near Sparwood in southeastern British Columbia. Since 1969, Kaiser has maintained a field-scale reclamation program dedicated to the reclamation of disturbances associated with past and present mining and exploration activities. Since that time, over 1400 acres have been treated using modified forestry and agricultural techniques with encouraging results.

Summary: The paper reviews the scope, timing and financial impact of this significant project, which involves the supply and transportation of nearly 4 million tons per year of bituminous coal and lignite from sources in British Columbia, Alberta and Saskatchewan to Ontario Hydro's generating stations. The critical factors involved in the selection and utilization of these coals are discussed in relation to the three types of coal to be utilized initially.
The paper then deals with each of the...

Summary: This mine is situated at Point Aconi, Cape Breton, Nova Scotia, and is a replacement for the 100-year-old Princess Colliery. It is a slope mine which is the continuation of a strip mine operation. There are five slopes from the surface driven with Dosco Dintheaders — this marks the first time these machines were used in North America.
There are four room-and-pillar sections, each equipped with a Lee Norse HH106 continuous miner, a "Top Dog" roof bolter and two Wagner diesel Teletrams. There...

Summary: High-voltage direct-current transmission is a relatively new technology. The successful development and operation of AC/DC converters, capable of handling large power blocks, have made HVDC transmission generally accepted by utility engineers and planners around the world. HVDC technology still has significant development potential and, as a result, it is expected that equipment costs will escalate at a substantially slower rate than those of conventional AC equipment. This development will...

Summary: The Sullivan Mining Group has been exploring the mineral deposits of the Mount Pleasant area of southern New Brunswick since 1967. Sullivan geologists have logged over sixty miles of drill core, mapped over five miles of underground workings and studied numerous surface exposures.
Several mineralized zones have been defined and two higher-grade porphyry-tungsten bodies delineated. Within these bodies, wolframite occurs as disseminated specks and grains up to one-half inch in diameter. The...

Summary: In 1972, a cooperative program to map and estimate the quantity of Tertiary coal resources in southern Saskatchewan was initiated by the federal and Saskatchewan governments. More than 700 exploratory boreholes were drilled over a two-year period, and data were obtained from other organizations on an additional 1500 boreholes in the area. Strati-graphic data and data on each coal seam penetrated in the boreholes, along with technical and location data for each borehole, were stored in a...

Summary: One of the most intensive of material rivalries is the confrontation between zinc die castings and plastic injection moldings. Pressed hard by the plastics industry, zinc die casters are learning how to make parts with less material yet without sacrificing quality. The key to this new trend is the technique of Thin Wall die casting. The obvious benefits of Thin Wall are lighter weight and lower cost. Again, obviously, these are the very selling points that put plastics into many appliance and...
