Abstract

The aim of this project is to analyse and overcome the limitations of existing systems for removal of coal from the coal face, and to develop automated methods of conveyor extension which will allow conveyors to operate continuously whilst they are being extended. The three main elements of tunnelling operations are excavation, support and mineral clearance. Huwood International were invited to cooperate in this project by developing the mineral clearance element because the achievement of a rapid rate of advance requires a coal clearance system to advance quickly and continuously behind the cutting machine. The main areas of research were: loop technology to allow extension of the system by 100 m between shifts and the ability to load belts automatically or semi-automatically; tail units with cassetted conveyor structure to allow advance of the conveyor system in step with the heading and interfacing with the tunnelling machine. A three-dimensional model of a system meeting the base specifications was produced. The system had to be capable of meeting the following criteria: advance rate of 60 to 120 m per day; maximum downtime for maintenance of four hours per day; maximum extension of 150 m per day; capacity of 250 t per hour. The results of the project are presented in this report.
