Quarry products such as construction aggregate are produced in a multindashstage processing operation that involves drilling and blasting extraction crushing and milling screening and classification As part of the MIST programme the BGS reviewed current production practices The detailed findings are on the goodquarry website and summarised in the production and process technology download.
The British Marine Aggregate Producers Association BMAPA commissioned BGS to examine the strategic role and importance of marine aggregates to the overall supply of aggregates in the UK It focuses on the sociondasheconomic issues associated with the production and use of marine aggregates and their contribution to national and regional supply The report is available to download from the BMAPA website.
In 2009 the BGS participated in research led by Camborne School of Mines part of the University of Exeter and funded by MIRO to assess the economic feasibility for underground mining for aggregates The research focused on whether or not aggregates could be produced and delivered to a local market from an underground operation in the southern and eastern regions of England at a cost comparable with that for production and transport from traditional surface quarries located further afield.
