GIS in Mining Industry

Geographic Information System is a set of tools for:

collection, processing and sharing of the datarequired for safe mining and modelling of:

• mine workings,

• structure and quality of the deposit,

• hydrogeological conditions,

• impact of the mining works to the surface.

Legal Regulations

Entrepreneur (Coal company) is obligated to maintain surveying and geological documentation.

Documents can be prepared in digital form if:

• are protected against damage and

destruction,

• there is a record of data changes in both:

archive and working files,

• files are printable.

Digital Deposit Model in PGG SA

AutoCAD Civil 3D is simple

GIS software which allowsconnection with databases likeOracle Spatial, can use WebMap Service, can drawingthematic maps, build and cleantopology etc.

Oracle Spatial - includes

high performance spatial, graphand analytics database. Itsupports GIS in the cloud andInternet.

Fusion Middleware SOASuite - Oracle Real-Time

Derivative maps

System can semiautomatically create derivative maps to the main map with different scale and annotations.

3D Model of mine workings

Generate automatically layout of workings in 3D based on flat map.

On this view we can present escape routes or we can design new workings.

Graph through multiple surfaces

Silesian University of TechnologyDeposit quality model

Similar to the seam floor surface – we can create another TIN surfaces containing coal quality data - like ash content, sulphur, thickness.

In AutoCAD Civil we can extrapolate data using kriging method.

Isolines description

✓ Thickness, elevation of the floor in every point

✓ Surface area, volume, inclination of selected polygon

✓ Quick dimensioning of selected object

✓ Impact of the projected mine plan on deposit and on surface

What gives us a TIN surface?

Longwall chart

Software can provide data about inclinations of the longwall in both directions, as well as longwall 3D length.

Data import from the surface

System automatically made plan of excavation.

Provides useful information: coal and rock tonnage, sulfur content, workings length etc.

Coordination between production,transportation, coal processingand sales.

Queries generation

➢ We can verify correctness of the modelled geology – for example whether there is no empty space between blocks – topology.

➢ System can be linked with external database – for example Oracle.

➢ System can be queried - highlight with green all blocks with thickness greater than 3m and all others highlight with red.

Work with aerial photographs

While planning production of coal we have to prepare information, buy of proper equipment with advance of many years.

Credibility of information containing the size of resources and the quality of coal is vital for coal mine to function properly.

AutoCAD and Geolisp can generate all necessary documents (reports, charts, thematic maps, etc.)
