Best practice and recommendations

The Mines Inspectorate expects all underground coal mines to have effective gas monitoring systems with suitably placed methane detectors to prevent explosive accumulations of methane in areas where it could be ignited. Best practices and recommendations to achieve this are outlined in this document for mine operations to consider.
