The feasibility of 6 m high single pass longwalling has been studied using Newlands Mine as a case study. An intensive geological investigation identified a range of hazards but a mine layout was possible that minimised the risks with respect to joints, cleats, angular bedding, coal shears and horizontal stress. Geotechnical design input was required for support capacity, subsidence, gate to face transition, face spall, and roof support. It is concluded that longwall face equipment can be made available by modifying existing designs, gate to face transitions will require a number of steps, and a mid-face sprag should not be required for routine operations.
