Mining & Ground Stability
The Mining and Ground Stability Report provides an accurate picture of ground stability issues surrounding a site. Exclusive to Landmark, this report contains MotionMap data which gives a precise picture of historical subsidence, heave or potential seismic activity.
Does the Mining and Ground Stability Report include data from the Coal Authority?
The Mining and Ground Stability Report will indicate whether your site is within a Coal Mining Affected Area. However it does not contain the details of Coal Mining activities on or near the site. This information is only available in a Coal Authority Coal and Brine Report which can be ordered from the Envirocheck website.

What is MotionMap?
MotionMap is ground motion data created by Fugro NPA and covering the period 1992-2002. The data is of millimetric accuracy and has been obtained using satellite interferometry technology, giving a precise picture of subsidence, heave or potential seismic activity. Scatter points are displayed on a 1:2,500 A3 map and presented in the data sheet, along with corresponding average velocity gradients. This is a partial data set concentrated in urban and semi-urban areas.
