Mine characteristics
The coal mine in the Mbeya Region of Tanzania has 600 workers,of whom 240 are involved in
underground tasks.It has operated at a capacity of 150 000 tonnes of bituminous coal per year since 1988.The coal seam is accessed through an almost horizontal entrance,where networks of underground roads are constructed for extracting and transporting coal to the surface for processing.Wooden props (timber) with caps (crossbars) are set to support the exposed roof and are allowed to remain in place as the face is advanced.Props with caps are also used to protect the conveyor,the working face and the intake and return airways.A reversible fan placed outside at a higher elevation ventilates the mine.The development site is a dead end,ventilated through an air duct,which has no air return,presumably making ventilation poor compared with other mining sites.
