Electronic push button control of the Longwall roof support system has been developed and tried in the US and Australia and is now sufficiently reliable. The aim of this project is to prove the equipment, and develop the concept over two faces in the more arduous conditions that exist in European coal mines. Maltby Colliery, South Yorkshire, installed a complete set of new face equipment for TO1's Advancing Unit, the first coal face in the newly opened up parkgate seam, where conditions were expected to be very heavy. This provided an ideal opportunity to fit the issue 'D' electrohydraulic control equipment as part of the support manufacture. The supports were to be installed underground and used on successive panels of coal, hence providing an ideal proving ground for the Gullick Dobson machine-initiated powered roof support systems.

The subsequent reduction of the market for coal in the United Kingdom resulted in the temporary cessation of coal production at Maltby Colliery. The project has therefore been indefinitely terminated. .
