The project involved review of the long-term slope stability and restoration proposals. Slope stability analyses to check existing slopes and to determine optimum extraction profile adjacent to land fill site were undertaken. Sensitivity analyses were undertaken to maximise mineral recovery.

The publication of MPG5:Stability in Surface Mineral Workings and Tips in January 2000 has reinforced the need for quarries to be adequately designed, stability being a material planning consideration. In this example, in order to achieve planning permission for a new quarry tip a report on the stability of the proposed structure had to be produced. Stability analyses were undertaken and a design and contract documents were drawn up to allow the construction of the tip. KeyGS’involvement included site supervision during construction and post construction inspections.
