Coal Mining Development Risk Plan
The coalfield is divided into two areas referred to as High Risk and Low Risk.
- The High Risk Area (15% of the coalfield area) is where coal mining risks are present at shallow depth which are likely to affect new development.
- The Low Risk Area (85% of the coalfield) is where past coal mining activity has taken place at sufficient depth that it poses low risk to new development
Coal Mining Specific Risk Plan
The Development High Risk Area (DHRA) contains 8 coal mining risks which make up the dark hatched high risk area. These specific risks are:
- Mine Entries with potential zone of influence
- Past Surface Hazards
- Past Shallow Coal Mine Workings
- Mine Gas
- Probable Shallow Coal Mine Workings
- Geological features (fissures and break lines)
- Workable Coal Seam Outcrops
- Surface (Opencast) Mining
Surface Coal Resource Plan
This plan illustrates the areas of Surface Coal Resources within each Local Planning Authority (LPA) administrative area. There is a need to ensure that mineral resources are not needlessly sterilised by new surface development. If LPAs fail to safeguard these resources, this may leave insufficient supplies for future generations.
