Monitoring and modelling progressive rehabilitation in aggregate mining ... A decade of ontario experience and a look at the future
- 28 Downloads
One of the main obstacles to easy minerals accessibility is nothing to do with the geological resource, rather, it is the past record of social and environmental damage and conflicts caused by poor mining practices. In Ontario much of this focuses on the issues of progressive rehabilitation—returning land speedily and effectively to some alternative, societally acceptable and productive land use. The public continues to be upset at the unwarranted removal of good farmland from agriculture— the lengthy period of its remaining in an unproductive and unsightly condition and the uncertainty of its being returned to a fertile condition.
Starting in 1971 the Ontario government became involved in regulatory control of the aggregate industry. After millions of dollars of research and a decade of experience, this paper documents the results. The paper isolates the main failings of the government programme and provides several models which if implemented will speedily remove the flaws and resolve much of the present public credibility problem with present mining practice and government control.

Reamenagements progressifs des exploitations de granulats...10 annees d'experience dans l'ontario et perspective d'avenir
Un des principaux obstacles à l'exploitation des granulats n'est pas d'ordre géologique. Il est dû aux conflits sociaux et environnementaux liés à l'exploitation anarchique des carrières.
Dans l'Ontario la plupart de ces zones sont réaménagées à des fins sociales ou agricoles. Depuis 1971, le gouvermement de l'Ontario contrôle la production des granulats et consacre des sommes importantes à la recherche de schéma-types de réhabilitation progressive de ces zones.
