Minerals Plan: Key Issues & Options

Derby & Derbyshire Minerals Core Strategy: Key Issues & Options

Appendix A: Glossary of Terms Used

The terminology used in this document is summarised below:


Abandoned Mine Methane - Can be recovered from previously working but now disused underground coal mines


After-uses - The use to which land is put once it has been restored following its working for minerals.


Aggregates - Materials such as sand and gravel and crushed rock, which are used in the construction industry for purposes, such as the production of concrete and roadstone.


Apportionment - The County's share of the Regional aggregate provision.


Biodiversity - The diversity of plant and animal life in a particular habitat.


Coalbed Methane - Can be extracted from some coal deposits by drilling wells into a coal seam


Coal Mine Methane - Can be recovered from working underground coal mines


Derby and Derbyshire Minerals and Waste Development Framework - The portfolio of planning policy documents which together will provide the spatial planning strategy for minerals development in Derby and Derbyshire.


Development Plan Document - Statutory documents produced under the Planning Acts that set out the spatial planning policies and proposals for the development and use of land.  Decisions on planning applications must conform to the policies set out in the DPDs.


East Midlands Regional Assembly - The body which has responsibility for preparing the Regional Spatial Strategy (The Regional Plan). As of April 2010, East Midlands Councils will take over these responsibilities.


Inert Fill - Waste material that does not undergo any significant transformations which can be used to fill voids left by mineral extraction to restore land to dry after uses.

Landbank - The stock of mineral reserves which has planning permission for winning and working.


Minerals - Technically, a mineral is a naturally occurring solid that has a specific chemical composition.   For the purposes of this plan, they are essentially rocks, which are an agglomeration of minerals and which can be used for a variety of economic purposes.


Mineral Consultation Area - An area (comprising the Mineral Safeguarding Area and a buffer zone) identified to ensure consultation between the relevant Local Planning Authority and the Mineral Planning Authority before non-mineral planning applications made within the area are determined, to ensure that valuable mineral resources are not sterilised. 


Mineral Planning Authority - The organisation which has statutory planning powers relating to mineral development in a particular area.  In respect of this plan, these powers rest with Derbyshire County Council and Derby City Council.


Mineral Resources - All minerals which have the potential to be extracted


Mineral Reserves - Mineral resources which have the benefit of planning permission for their winning and working.


Primary Aggregates - Naturally occurring material which is extracted freshly from the ground to be used in construction.


Recycled Aggregates - Recycled waste products from the construction and demolition industry, including concrete, rubble and road planings that is crushed and can be used in place of primary aggregates.


Restoration - Operations which are designed to return an area to an acceptable environmental state, whether for the original use or for a new use following mineral working.


Safeguarding - Protecting valuable minerals from being sterilised by other forms of development so that future generations have a sufficient supply of these minerals to meet their needs.


Secondary Aggregates - By-product wastes, such as power station ash and colliery waste that can be used for low grade aggregate uses.


Soundness - Whether the plan has been prepared in accordance with a series of nationally agreed tests and procedures.


Special Areas of Conservation (SACs) - A Site of Special Scientific Interest (SSSI) which is considered to be of international importance, and designated under the EC Directive on the Conservation of Natural Habitats and of Wild Flora and Fauna.


Sterilisation of Mineral Resources - When development of land prevents possible mineral extraction in the foreseeable future.


Super Output Areas - A geographical area designed for the collection and publication of small area statistics.


Sustainability Appraisal - An evaluation process for assessing the environmental, social, economic and other sustainability impacts of plans and programmes.  It is a statutory requirement under the 2004 Planning Act.


Underground Coal Gasification - An in-situ process whereby non-mined coal seams are converted into gas
