Minex Modelling Flow chart 1. DATA
BH(bore hole) Data Survey Data Collar > Fault data Litho > Pit/survey Data Quality > Lease boundary etc. Seam
2. Creation of New Format Project Manager
New
3. Go to File system
Set project Directory
4. Create i) BH data base & ii) Geometry data base File New BH / Geometry data base 5. Add data type to data
*.B31 /*.GH3
box Select BH data box Read only false For each data type create variable
6. Load Collar data need to create format files then match the Minex variables Sample data with*.csv variables (Litho/Qual/Geophysics) 7. Go to BH DB Edit Create seam sequence Save to new layer file Give the name *.B31 i.e. database name & save 8. Loading the seam file (*.csv) to minex (csv file)
BH ID
From
To
Seam name
Seam class
BH DB Load Load seam layer area Select the file Give a format file name [OK] Class = seam class & name = seam name 9. Plotting of BH along with seam (3D) BH DB plot BH display 10.Generation of reports for validation BH DB Report Collar data Seam data
Sample data with different variables
In case the compositing values for the seam are not available i.e. only band by band analysis is available we have to compute the data w.r.t. length. 11.Compositing Select the *.B31 data base
In “properties” make read only False In “percentage of seam to be sampled” the default value is 100 change the value 80% (100 – 20) From 5.0 6.0 6.5 6.8 7.2
To 6.0 6.5 6.8 7.2 7.9
Thick 1.0 0.5 0.3* 0.4* 0.7
Ash 20% 15% 30%
*(0.3+0.4)/2.9 =20% As such % of seam to be sampled will be<100 – 20> Seam Sampling Tolerance Use seam sampling tolerance True give % If any ply is falling partially within the seam roof or floor to include the same give tolerance w.r.t. length i.e. 05/0.1/0.2 etc. 12.Creating values with fields for data type while reporting (optional) SQL programming For enabling Enable SQL [true] Select SQL file SQL
Select the desired field [change it to SQL format] File
create
SQL (*.SQL file)
Edit the SQL file [SQL editor] write the code Report
Seam variable
Select the SQL
variable 13.Seam splitting Seam model tab]
BH seam operations [ click on ply splitting & merging
Parent Define A A Default Pick type: Estimated
Child A1 A2
14.Set missing seam [ click on tab ‘Missing seam’ ] 15.Set seam thickness to zero for missing seams for interpolated seam 16.Create the DD 17.Create grid
Unfault if fault Refault exists Quality structures (original) add variables SF – seam floor ST – seam thickness
18.Plot the faults 19.Generation of faults Seam model
unfault
& refault menu
Fault definition (tab)
picks faults (3D)
Fault block generation
vertical shift only
Set limit (ON) [take default limits] Generate fault block
Unfault BH tab Save (give name) unfault data base Make unfault data base current (tick)
20.Seam model
multiseam multi variable griding Select Output DD as [ unfault] Add variables select seam gridding parameters update lists 21.Stacking surface for final modelling Create a new DD model Seam model seam model operation Input DD: unfault Output DD: Model Select operation: Model Building stack name cut off seam (tick) 22.Seam model multiseam multi variable griding Give unfault DD name Give refault DD name [ Select seam, Variables, (Base RL & Seam roof) 23.Open original database *.B31 24.Flatten Seam model unfaulting & refaulting model Select seam Select variable Give a reference grid (say topo) Mesh size : (small) Output DD : Flatten 25.Reserve Estimation Seam model seam insitu reserve report Seam Θ All, create list Set the limits in (Limit tab) [OK] Unlimit & downlimit
flatten normal
26.Seam model seam detail reserve report Seam default tab: select the seam Surfaces tab: select suffix for thickness & density Quality tab: quality variables to be selected Limits tab: topography, weathering & lower limit grids to be selected, area selection (polygon) Report tab: define your classes Defining the template [create edit template] Add variable Calculate variable Keys (for sorting) Global summary (for summation) Save the template Give report name csv format (*.csv file) (tick) Open file by default application (tick) 27.Pit designing Requirements: i) Merge grids ii) Bench list iii) Pit boundary 28.Creation of merge grids Create DD Merge Pit design create merge model Use reference grid Θ Merge up Select topography & weathering grid Input DD: Model Output DD: Merge Select seam:All [OK] 29.Create Bench grid for creating bench list [ create new DD : Bench grids] Pit design create bench grid Resume grid Limit on top grid preferably for merge grids Limit on base grid Generate list [ OK] 30.Creation of bench list Pit design bench list Pit Θ Pit crest grid [ topography] Grid directory: bench grid Fill with grids save OK (*.BLS file) 31.Pit
design pit design Give a pit no Design bench digitise Select the boundary string Design - automatic Project down Design strips Digitise 1st strip Design offset (give the required number) Design (Automatic) o Project down (all strips in all benches)
Design (first /last) o Digitise two limits Design (strip end) [OK]
32.Create Blocks Design : Blocks Digitise layout lines Give block width Generate block for all the benches Checking blocks for all the benches Checking blocks by displaying 33.Design : Blocks: Display Reserve within mining blocks Reserve database 34.File New DBR Give name & save [ reserve DB.DBR] 35.Reserve Initialize Edit cores & layers Select seams update code info save the layer (*.OLC file) 36.Reserves Initialise Select pit no & large file
Add Pit
37.Reserve Build Generate reserve Select reserve DB file Select geometry database (specify geometry file) Select the structure DD name : Merge Select the bench DD name : Bench grid Select Autorun : OK Reserves will be generated for all the blocks 38.Reserve reporting i) select pit [OK] ii) select variable, select pit report name [OK] 39.Reserves Plotting -- 3D display
