Surface protection
1. Forecasting continuous deformation of the mining site
· development of basic, detailed, and approximate predictions of W.Budryk-S.Knothe’s
theory patterns for the final state of deformation, as well as for the
undetermined state, using proprietary software called DEFK-Win.
· preparation of graphic documentation to interpret the results of forecasts using CAD software – commercial and authoring software called Surfcad.
We make maps of the projected hazard categories of the mining site, maps of the distribution of values of any deformation indicators, including illustrating
the projected directions and values of main horizontal deformations, and maps of the distribution of horizontal deformations surrounded by calculated points.
· performing detailed analyses of the impact of underground mining
operations on construction works using computer simulation of the course of the
operation and related variables during deformation.
2. Forecasting continuous rock-mass deformations
· development
of forecasts of the impact of underground exploitation on shafts and corridor excavations,
· spatial
analysis of projected mining deformities caused by underground exploitation, using
commercial software that allows 3D visualization of deformation distribution.
3. Forecasting changes in land sculpture caused by underground mining operations
· development of projections of changes in surface formation caused by underground operation for final or instantaneous reduction values taking into account the space-time development of the operational front.
4. Determination of the end time of post-operation surface movements for mining investment processes and mining damage claims
· analysis
of the results of levelling measurements to determine the end time of the post-operation
movements of the rock-mass and surface,
· determining
the end time of rock-mass and surface movements for investment processes in
mining areas. The rating may apply to selected locations or entire areas (in
such cases, we make maps with the location of areas with different end times of
movements),
· determining the time of termination of movements of the mining site in cases of claims for recognition of damages in properties.
5. Design of underground operations taking into account the principles of minimizing its impact on the surface and rock-mass
· evaluation of underground exploitation projects for the protection of the-rock mass and surface,
· planning the selection range, order, and directions of the operating fronts taking into consideration the protection of construction works (including mining prevention).
6. Identification of the values of the parameters of influence prediction theory
· analysis
of the results of measurements of surface and rock-mass deformities,
· determination of the values of geometric-integral theories for established and undetermined states for underground exploitation impact predictions, using proprietary computer software.
7. Forecasting discontinuous deformations
· assessment
of the degree of surface hazards due to the potential for discontinuous surface
and linear type deformations based on geological and mining documentation,
together with the prediction of the occurrence of cave-ins on the surface,
· analysis of the possibility of shallow voids in the rock-mass because of the surface hazards of discontinuous deformations employing electro-resistance tomography method, and using modern measuring equipment.
8. Development of computer software in the field of rock-mass mechanics, the impact of underground exploitation on the rock-mass and surface, and other mining sections
· the ability to make computer software to order, according to the customer’s needs, using modern IT tools for Windows operating systems.
