Technological innovation and Canadian coal mining

Abstract Technological innovation is an extremely complex activity. The author presents his interpretation of innovation and the innovative process. He reviews the strategy used by participants in coal mining innovation in the past and discusses changes required to meet the challenges of the future.

Summary: The paper briefly describes the development of the Eickhoff ESA60 roadcutter which is based on the old and well used principles of the shearer loader. It is intended to show that the machine offers a viable alternative to the normal methods used for driving roadways and also for coal production. References are made to installations currently operating in Europe with applications ranging from roadway drivage to pillar recovery. The paper also looks at possible applications in Canada.

Summary: This month, Tax Notes focuses on two features which can potentially "dress up" a new issue of common shares to make the shares more attractive to investors. Attaching warrants to a share issue is a relatively common practice, and recent years have seen an imaginative variety of different kinds of warrants, some of which can be subject to somewhat different tax treatment. A less common financing strategy which certainly deserves some consideration involves the possibility of...

Summary: One approach to making new technology available is to demonstrate its value under full-scale operating conditions. Studies were undertaken to assess the feasibility of this approach to introducing a longwall mining system to the western Canadian coalfields. The longwall method of mining coal is described, world and Canadian usage is reviewed, and the merits of the system in comparison to other coal mining methods are discussed.
The rationale for a longwall demonstration in western Canada is...

Summary: CoaLiquid, Inc. (CLI) has been in the coal-oil-mixture (COM) business for over five years. The initial pilot processing facility was replaced by a 2000 barrel per day commercial production facility in August 1979. For over two years CLI has been expanding its efforts and conducting large-scale production and combustion demonstrations successfully in many locations across the United States. To facilitate the marketing effort, CLI has recently constructed a special trailer containing all...

Summary: The consolidation of mine backfill by freezing is a concept which has been under study in the mining engineering laboratories at Laurentian University during the past three years. The proposed underground application of freezing involves the artificial freezing of in-situ backfill by means of a refrigerated brine solution which would be circulated through a circuit of freeze pipes. The most interesting findings to date are: (1) The uniaxial compressive strength of frozen fill is considerably...

Summary: Spontaneous combustion has always been a problem in coal mines and is identified mainly with the mining of low-rank coals. The liability of coals to spontaneous heating is only one of the factors in determining whether spontaneous combustion will occur. However, knowledge of the relative oxidizability of the coal is a useful factor to take into consideration when selecting new coal seams and mining methods for future mine development.
Four methods (static isothermal, ignitability, adiabatic...

Summary: Pilot precipitator tests were conducted at Noranda's Home Smelter in late 1978 to evaluate methods of improving converter dust collection efficiency. About 35 Nm3/min. of converier off-gas were isokinetically diverted from the converter flue to the pilot precipitator leased from Flakt (Canada) Ltd., consisting of three fields, one transformer-rectifier set per field and 77-m2 total collecting plate area. The effects of gas volume flow rate and conditioning the gas with sulphur trioxide and/or...
