As coal mines get deeper, more mechanised and more productive the heat load on the ventilation system increases. In certain cases to the point where serious environmental problems may arise. To continue mining in these demanding conditions the sources of heat must be identified and evaluated so ameliorative measures may be taken. Due to the

The most common slope failure of spoil piles was observed when the mine strip was filled with water and then dewatered, specifically a drop in the water level at the base of a slope from the dewatering process. As most of these slope failures can be caused at the

DEVELOPMENT AND DEMONSTRATION OF A STANDARD

Results of this thesis indicate that a comprehensive dust characterization method is possible and can be efficient and effective, when standardized. This analytical approach uses measured compositions, dimensions, and shapes to produce an abundance of data in even a single sample of dust. Verification results show the method is suitable for analysis of respirable particles of common coal mine

THE NEGATIVE IMPACT OF ABANDONED COAL MINE WORKINGS

The Nanaimo Coalfield was a major coal producer between 1852 and 1968. During this time, coal was mined extensively in the area of South Wellington. The quality of groundwater in South Wellington may be adversely affected as mine site abandonment causes a deterioration of the hydrological system. This thesis employed a case-control

The Social and Environmental Consequences of Coal Mining

To these coal mine owners it was more important to keep the costs of their own energy inputs low, than to profit from coal mining itself4. The coal price remained very low until the mid 1970s, when export opportunities opened up through a deep terminal in Richards Bay, and Japanese long term contracts. The low coal price was accompanied by harsh working conditions and low wages for African
