FIND A OPTIMIZED SITE FOR A NEW OPEN CAST MINE

Site Selection for a new Quartzite Quarry

quartzite as building material possible conflicts (land use and contamination of the environment) consideration process necessary data ArcGIS workflow



Building Materials

Sand and Gravel Natural Stone Limestone, Dolomite Clay other industrial minerals

around 600 Mio. t of raw material in Germany per year 6400 operations 137000 employees 21.5 Bill. sales



Quartzite

quality criteria is SiO2-concentration use for fire proof materials or as natural stone or as ballast in railway

construction, etc. mining in open casts transport with trucks Low quality with low market value --> only short transport routes possible



Quartzite



Project exercise

Find the best location for a new quartzite quarry - optimized location factors - minimized conflict potential

reasoning and presentation of result from a GIS analysis and

preparation of a thematic (GIS-) map



Some sorts of Conflicts

conflict of needs (e.g. recreation - mining) conflict of values (natural protection supply of raw materials) conflict of distribution (contribution of areas within a community)

potential of conflicts for a company

(any circumstance, which leads to change of economic or technical planning)

conflict parties (authorities, association, legislation, people)



Consideration Process (I)

location factors conflict potentials

landscape development plan natural protection landscape protection water pollution control protected landscapes Fauna-Flora-Habitat National Parks species and biotope protection settlements open water bodies and rivers recreation areas and routes hiking trails power supply line

modelled ore body Ore reserve estimation geological maps of

quartzite bodies within investigation area (Saarland)

topography

logistic aspects regional markets



Mining of Raw Materials is restricted to specific Locations



Estimation of Ore Reserve

production at least 200000 t per year production period at least 20 years maximum depth of 20 m.

specific weight of quartzite: 2600 kg / m known thickness of layer: 20 m

base area at least 77000 m 20m

What modules do we need?

ArcCatalog (working directories, data connections, preview, meta data, etc.)

ArcMap

(presentation, editing, analysis, layout and mapping, etc.)



Workflow

work preparation

(digitizing) (ArcMap Editor)

buffering (ArcToolbox)

spatial analysis (ArcToolbox)

results (ArcMap)

mapping (ArcMap)



Work Preparation

login with your tu-clausthal account

creation of working directory D:/this_is_my_name/ D:/this_is_my_name/data D:/this_is_my_name/results

copying the data copy all data from folder D:/Quartzite/ into the working_directory/data folder



Work Preparation in ArcMap

define Coordinate system (DHDN, Gauss-Krueger Zone 2) name layer stack (e.g. Quartzite quarry) activate Extensions

Toolbox, Menu: Tools, Editor, etc. Layer-concept, order, properties

open online data sources and Layer organization

- ESRI World Street Map 2D - openstreetmap - TK 25



Adding data in ArcMap

adding data and grouping layers in ArcMap

- TK - elimination areas - consideration areas - location factors - maps - results / intermediate results

adjustment of transparency adjustment of symbols adjustment of labels



Editing in ArcMap

digitizing of - rivers - open water areas - additional transportation roads

symbolizing labeling setting of attributes



Buffering in ArcMap

electric transmission lines (50m) railways (50m) All streets, roads & highways (100m) water protection (type I and II only => 100m) open landscape priority (100m) nature priority (100m) wind farm priority (100m) groundwater withdrawal (100m) nature protection (100m) settlements (300m) protected landscape (100m)

state border ?

groundwater priority (100m) agriculture priority (50m) landscape protection (100m) forest (50m) biotope protection (100m) Fauna-Flora-Habitat (100m) mineral resources (50m) scenic roads (300m) cultural locations (300m) touristic locations (300m)

natural parks ?

elimination areas consideration areas



Quartzite Areas minus Elimination Areas

union: merging all buffered elimination areas erase: cutting out all elimination areas

from quartzite multipart to singlepart: discretization add field area calculation (Field_Calculator) selection (Selection_by_Attributes:

area > 77000 m) create new layer from selection save new data set



Quartzite vs. Consideration Areas

buffer the consideration areas add field: new field Consideration edit field: insert name

of consideration purpose union: consideration layers identity: consideration layer and

quartzite layer (delete / hide empty fields create layer from selected features) estimation of conflict value change symbology: categorize

by a probability / or the sum of conflicts

Location Factors

Remaining areas > 77000 m

Remaining areas > 77000 m with a conflict potential of < 30

investigation of location factors for these areas:

infrastructure (distance to) highway energy supply roads water supply / waste water

size of quartzite area possibility of enlargement topography distance to settlements
