Deliverable D2.2

Deliverable D2.2  – Sinkhole database. This document describes the creation of a database of sinkhole (Work Package 2 – Task 2.2) linked to shallow abandoned coal mines in Europe (WP2 – T2.1) including those due to the collapse of old mining shafts.  The objectives of the database are:  collecting the maximum number of well-documented cases across the Partner’s countries including information on the circumstances of the occurrence of sinkholes and  constructing Web-map for displaying of the identified cases at different scales: sub-regional, national and continental one.
