A common practice for Tactical Mine Planners is to do the Life of Mine Plan and break it into short-medium term schedule. However, there are some instances when we have an existing production schedule and we would like to incorporate this to a Life of Mine study.
Following the creation of Haul routes and running the schedule to get the results in MineSched, if you want to modify haul road strings in Surpac (GMP), you can use MineSched to update it quickly and easily using the following steps.
This post explains the steps for using Retard tables with empty trucks in GEOVIA MineSched, continuing from the previous discussion on Rimpull tables. It provides background on Rimpull/Retard tables in MineSched 9.2 and later versions, using the CAT 973D as an example, while emphasizing that other trucks can also be applied.
This blog aims to provide MineSched users with a background on Rimpull/Retard tables and explaining how they are used in MineSched 9.2.The CAT 973D is used as an example to explain the concept of Rimpull/Retard tables but it has to be emphasized that other trucks can be used in MineSched.
When do you use Rimpull or Retard tables?
It is important for mine planners to report numbers that are as accurate as possible when generating mining schedules. GEOVIA MineSched, as a planning software of choice, provides the user with an option to increase the level of accuracy in the volumes and tonnages through the partial percentages option when reporting quantities in either solids or polygons.
Why use partial percentage?
Mining engineers may want to visualize block models inside GEOVIA MineSched to both orient and understand their schedule better. This will allow them to better relate their schedule setup to the actual blocks they are interested in and see the results of their schedule superimposed on a saved DTM.
The following steps will allow users to open block models that have been created in GEOVIA Surpac, in the MineSched program.
Tracking haul routes in mine planning can be complex, especially with multiple destinations like dumps, ROM, and TSF. The latest version of MineSched simplifies this by allowing unique naming of each route, making road networks easier to map.
With Surpac, engineers can assign haul route names to description fields and then import them into MineSched. Once imported, routes can be intuitively mapped to their destinations, streamlining haulage scheduling and material movement planning.
Sometimes data is provided in CSV format from other packages that contain Latitude and Longitude information. To ensure this data to be seen and read in Surpac, it is necessary to convert the data into a grid reference system. In this example, the reference will be MGA94, however the technique can be equally applied to other grid systems.
In MineSched we can sequence the deposits (fill locations). Fill locations are fixed volumes and defined by block model, which are the final destination of materials. Once the material sent to a fill location, it cannot be moved to another location of any kind. To do this, we must create dump models so that MineSched has a volume of material to destine this material. The following example indicates a quick technique for creating block models designs from design in Surpac, and subsequent use in MInesched.
In pit design, engineers often need to adjust slope angles and berm widths based on rock stability. GEOVIA Surpac supports this by using values stored in the D-field of the pit design string file, with slope angles taken from D1 and berm widths from D2, enabling precise and flexible pit design.
