Recent projects include:
UK and Ireland
GWP has worked with major cement producers in the UK and Ireland. Recent projects include:
- raw material characterisation and quarry design for a major new cement plant;
- re-evaluation of UK resources for a major international cement producer; and
- design of major extensions as part of planning applications to extend reserve life.
GWP have provided operation support in relation to:
- the safe disposal of CKD;
- optimum working layouts;
- costs and benefits of ripping vs blasting;
- geotechnical assessments and training;
- hydrological impacts of quarrying; and
- detailed surveying and reserve audits.
Nigeria
Design and management of hydrogeological investigations in a sub-artesian, semi-karstic, multi-aquifer limestone sequence at two major operating sites with the objective of assessing the feasibility and cost of de-watering to release 150Mt of limestone resource for a capital investment project for new kiln lines.
India
Design and management of drilling and sampling programme for cement raw materials at a greenfield site followed by geological and geochemical modelling, reserve evaluation and conceptual working scheme.
Libya - Benghazi
- Design of the quarry layout accommodating modern, efficient and safe working methods while meeting limestone and clay requirements at the plant before and after expansion.
- Assessment of the quality and quantity of remaining clay in the quarry and devising working methods to ensure its efficient working and use.
- Design of a waste cell for the conatinment and isolation of future CKD.
Croatia
Creation of a range of alternative quarry designs at a cement raw materials quarry in Croatia. Selection of a new mine plan was based on the need to moderate the short, medium and long term environmental footprint of the operation and achieve a compromise between permitted, economically viable reserves and local spatial plans which seek to restrict the mining area.
Option selection was driven by three interrelated objectives:
- the need to secure sufficient reserves for the continued operation of the two cement works served by the quarries for a minimum target period;
- the need to moderate the short, medium and long-term environmental footprint of the operation. Key issues were visual and landscape impact, limiting blast vibrations and dust nuisance, and delivery of a final restoration landform suitable for a beneficial after-use;
- the need to respect a community desire to increase stand-offs from residential property and sensitive structures and locations.
Ethiopia
Provided all raw materials related inputs to a pre-feasibility and feasibility study for a major cement works expansion project at Mugher (for Mugher Cement Enterprises), including:
- review of local regional exploration mapping and site selection for limestone, clay, sandstone, gypsum and pumice quarries;
- specification of site investigation in all deposits and specification of standards required;
- analysis and modelling of geological and geochemical data from the drilling programmes;
- reporting on the reserves;
- environmental audit, focusing on water and dust;
- design of the mineral operations including detailed quarry layouts.
