To return to the start of each main activity area click on the hyperlink in any row in column A of a worksheet.
The data in this workbook was compiled by assessing for each type of coal mining activity or element the hazards that could be present, the mechanisms driving the hazards and controls for those mechanisms. The original data was compiled by multi disciplinary teams comprising Mineworkers, Mine Management, Mines Inspectorate and where relevant other experts from various fields of expertise. In total over 80 industry personnel were involved in the process which culminated in the development and enactment of the Coal Mining Safety and Health Regulation 2001. The initial database, from which this Excel version was made, was constructed in a Lotus Notes format by the Technical services unit of the Queensland Mines Inspectorate.
NOTE - Although developed for use in the coal mining industry, many of the hazards, mechanisms and controls have applicability in metalliferous mines, quarries, general construction work and bulk transportation. This particularly applies to hazards such as diseases, exposure to noise, vibration and dust contained in the General section WORKBOOK The workbook comprises three sections- General Mining Hazards, Surface Mining Hazards and Underground Mining Hazards. Each section is then divided into a series of worksheets that cover the Hazards likely to be encountered in each main activity area of the respective section. This follows the format of the Queensland Coal Mining Safety and Health Regulation 2001 To access any section click on the section hyperlink below
WORKSHEETS The main activities in each section are accessed by clicking on the hyperlinks on each section introduction screen. Each main activity worksheet contains, as a minimum, a listing of hazards, a listing of mechanisms that can cause those hazards, controls that could be adopted to control the respective hazard and references that can be consulted. Some main activity sheets with many facets are further subdivided into sub activity categories. NOTE In this revision (No 6) there are hyperlinks from the Hazard worksheets to 16 Significant Incidents, 46 Safety alerts and 14 Safety Bulletins and links from the respective incidents, alerts and bulletins sheets to the Hazard worksheets To return to the opening screen of each section (General, Surface or Underground) click on the hyperlink at the start of each main activity area
