A circular "faceheader" tunnelling machine developed by the MRDE is to be used on driving a roadway at Cadley Hill Colliery, South Midlands. The machine, based on a standard full-facer and a boom-type roadheader, will drive a 1500 M long, 5.5 M diameter tunnel through sandstone, shale and coal some 450 M below ground level. The tbm's thrust ram will also be used in conjunction with a seven-segment concrete block system lining used for the first time in the UK coal industry. The seven-segment rings - three articulated blocks connected by tie-bars - are designed for easy handling. The tbm is said to offer a cheaper and more versatile method of tunnelling in UK mines. Details of the machine's performance and method of advancement are given. (TRRL)
