Various hazardous gases are emitted in working underground coal mines of which methane and carbon dioxide rich mixtures are the most common. The risks associated with these gases can be minimised by diluting them to safe concentrations or by capturing gas in boreholes. This report reviews the ventilation and gas drainage practices that have been developed in various countries to facilitate the working not only of gassy seams but also those that are prone to instantaneous outbursts of gas and coal or rock. The report was prepared by Wardell Armstrong in collaboration with CSIRO, Australia. An annex to the report, written by the China Coal Information Institute, describes the situation in the extensive Chinese coal industry. There is considerable scope for improving gas control in underground coal mines, particularly in the non-OECD countries where the frequency and severity of gas-related incidents are unacceptably high. The report stresses the importance of health and safety management systems, safety legislation and enforcement, human attitudes, training, planning and equipment maintenance, to the successful implementation of existing or new technology.
