Stowage Material

Nantgarw colliery is the subject of a major reconstruction scheme, the details of which are of interest to mechanical engineers. Many of the major features including the shafts, winding engines, air compressors, mine-car handling equipment, and stowage material preparation plant are outlined in this paper. Because of the necessity to wind from more than one level in the pit, the shafts have equipment which is a departure from the conventional types in use in Britain. The method of mining to be used is known as the “Horizon” system, well favoured on the Continent for steeply inclined seams. The chief feature of the system is that horizontal roadways are driven to the seams at convenient vertical distances apart. The use of compressed-air power is mentioned, together with reasons for the choice of the air- compressors installed. The system of transporting coal and materials within the colliery is dealt with at some length, because of its originality and its improvement over the systems in being at the older collieries. A fairly full description has been given of the shale preparation plant for stowage material for underground use. This is the first plant of such a size to be designed in Britain, and it has been developed from experience gained in smaller units built at nearby collieries.
