Minex Underground Mine Planning is a state-of-the-art system for the design, resources computation and scheduling of underground mining for stratified deposits. Integrating current underground mining practices with advanced interactive graphics and Critical Path Method scheduling techniques, Minex provides a cost effective system for rapid evaluation of long or short term mine plans.
Minex is applicable to:
-
Coal or other layered deposits.
-
Bord (room) and Pillar extraction techniques.
-
Advance and retreat longwall extraction techniques.
-
Wongawilli pillar extraction techniques.
Reserves are built directly off the geological model. Each panel stores
tonnage and quality attributes that reflect changes in the geology.
Unlike other systems, panel averages are NOT used, so there is no need to draw lots of small panels or blocks. Reserves are calculated in minutes, and dilution models easily included. When reserves are calculated, equipment working height constraints are taken into consideration.
| Scheduling "Scheduling with pictures" is the best way to describe the interactive scheduler. Scheduling is simply point and click, with 3D symbols of mining equipment, and panels being shaded (colour coded by equipment item).
The planner, at a glance, can see a snapshot of the current state of the schedule.
Numerous features include being able to step forward a set number of days increment, step backward (rewind schedule) to a specific date or location. |  |

Design is a simple process. The user defines a library of common panel geometries (number of roadways, pillar and roadway dimensions etc). A centreline is digitised and the panel boundary automatically generated.
Numerous design tools are available within the 3D graphics environment including co-ordinate geometry (COGO) survey functions. Note pillars (designed or surveyed) can be used to calculate reserves. |
Auto Layout
Imagine creating a complete longwall mine in minutes!!. The auto layout allows the user to draw a group of panels (mains, gates, and longwall) based on a selected component specification for each. Then by dragging the face install panels, the whole longwall panel is shortened or lengthened, as required.
Many options can be analysed, before committing to a detailed design.
Longwall Optimiser
Calculate the optimum path that the Longwall should take through faulted seams, to minimise the amount of rock mined, and still maintain cross and long gradient limits. The longwall optimiser works off a gridded seam model.
It can be used in two modes:
-
To tell you how to mine through faulted ground, and be constrained to existing gate roads.
-
To yell you where to put the gate road before the longwall commences mining.
Plotting and Reporting
Presentation quality plots are easy to generate.
Select the type of plot:
-
Incremental advance,
-
Detailed barchart,
-
Equipment usage, and
... add titles, legends and text to complete the picture. Overlay your mine plans on the geological information. The CGM plots files can be inserted into MS Windows products to create reports and presentations.
Several standard reports are available including panel start-finish dates, tonnes and distances mined, as well as user customised reports. Reports are readily imported to spreadsheet programs.
