Northern Pipelines and Southern Assumptions
Two commissions of inquiry were appointed by the Canadian government to investigate the likely consequences for the land and peoples of northern Canada affected by pipelines proposed for the delivery of Alaskan natural gas to American markets. The author compares these two commissions which were chaired by Mr. Justice Thomas Berger and Mr. Kenneth Lysyk respectively. He sees them as together illustrating that the problems of northern development do not begin in the north, but rather in the minds of white people from the south because of their assumptions.
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions of subsidence at a coal mine panel for which a considerable amount of data was available in the literature. Some aspects of the selection of material properties and the shape of the subsidence profile are discussed.
