| Zusammenfassung |
The paper presents the concept of the deformation information system (DIS) to
support and facilitate studies of mining-ground deformations. The proposed
modular structure of the system includes data collection and data
visualisation components, as well as spatial data mining, modelling and
classification modules. In addition, the system integrates interactive
three-dimensional models of the mines and local geology. The system is used
to calculate various parameters characterising ground deformation in space
and time, i.e. vertical and horizontal displacement fields, deformation
parameters (tilt, curvature, and horizontal strain) and input spatial
variables for spatial data classifications. The core of the system in the
form of an integrated spatial and attributive database has been described.
The development stages and the functionality of the particular components
have been presented and example analyses utilising the spatial data mining
and modelling functions have been shown. These include, among other things,
continuous vertical and horizontal displacement field interpolations,
calculation of parameters characterising mining-ground deformations,
mining-ground category classifications, data extraction procedures and data
preparation preprocessing procedures for analyses in external applications.
The DIS has been developed for the Walbrzych coal mines area in SW Poland
where long-time mining activity ended at the end of the 20th century
and surface monitoring is necessary to study the present-day condition of the
former mining grounds. |
