Case Studies: High Speed Development Conveyor System

To achieve the rapid advance rates required to open the development of the new seam at Hatfield Colliery, two Philford designed and manufactured ‘walking’ 500 centres 22mm AFC chain conveyors, complete with crushers mounted on the receiving section, were initially installed. 

Due to the success of these installations, four Philford designed and manufactured ‘walking’ belt type receiving sections, complete with Philford’s heavy duty bridge belts, were installed in the major drivages. These units carry all the equipment required for long drivages – switch panels, fans, cables etc – and can include man-riding platforms. Downtime due to advancing these ancillaries and belt ‘move ups’ is vastly reduced because the whole receiving section can be advanced without stopping the heading machine. Hatfield Colliery Deputy Colliery Manager Brian Holland said: ”Philford is certainly producing the goods for us.“
