摘要

Coal was first mined in Cape Breton, Nova Scotia, Canada in 1685, by the French military authorities, from the exposed coal seam outcrops. By 2001 the last remaining underground coal mine in the Sydney Coalfield had ceased operation and so began the legacy of mine water in Cape Breton. More than fifty underground coal mines have worked the three major coal seams in the Sydney Coalfield, producing an estimated 500 million tons of coal and waste rock, thus leaving enough void space for more than 50 billion gallons of ARD producing mine water. At present there are several large groups of interconnected and abandoned coal mines or "hydraulic systems" within the Sydney Coalfield that are flooded to equilibrium, and there are several other hydraulic systems that are in the process of flooding. One such group of ten interconnected mines that is partially flooded is referred to locally as the IB Hydraulic System. This paper addresses the mine water management techniques that were developed to prevent a discharge of deleterious mine water to the environment from the IB Hydraulic System and outlines the plans for the future.
