The mining of thick, flat coal seams by a longwall bottom slice with caving and drawing / K. Barron, Mining Research Centre.: M34-20/189E-PDF
“A method, developed in France, for mining thick, flat lying coal seams is described in detail. A longwall face is retreated along the footwall of the thick seam and is supported by powered supports which incorporate a special banana prop at the rear. The coal overlying the face caves behind it and is drawn through the banana props onto a rear face conveyor. Face advance is achieved either by hand mining or by using a conventional double drum shearer. Details of the mining method, problems encountered and good and bad mining practice are discussed. The capital and operating costs, the production and productivity in France are given. Ground control and environmental control problems are also discussed. Consideration is then given to the potential use of this method for mining thick, flat lying, coking coal seams in Western Canada"--Abstract, p. i.
