ICAMPS MineSimU
Simulated Mining - Underground Mine Planning Software
|
|
|
|
|
| |
|
MineSimU is used to create detailed tonnage reports and timing maps. It has daily scheduling and monthly scheduling. In MineSimU production and quality forecasts are specific to the area mined each time period, not long term average values. It gives accurate results, rapid computations and convenient editing features which allow the mine engineer to try numerous scenarios and find the best combination of operating practices and mine design. Based on training experience, a mining engineer can learn MineSimU and have his mine plan up and running within a day. After that the mining engineer can go back and try different scenarios within an hour or two.
MineSimU has a variety of reporting options. Reports can be printed directly from AutoCAD or exported to third party software like Excel and Report Writer. It has extensive Royalty Reports and a very flexible function to view and draw the timing maps allowing for solid fill, hatching, and various labeling options.
MineSimU has the ability to adjust the mining rate based on seam height, difficulty code, time periods, by area or by machine. |

Geology Features |
|
|
|
|
| |
|
The simulated mining module requires geological and quality data in order to compute the total material mined (raw tonnage), processed tonnage and raw or processed quality for each timing sequence.
ICAMPS accepts gridded seam models from MineSurf or other geological modeling systems. Individual parameter grids are combined into a master grid which contains up to fourteen parameters. A master grid must be assigned to each mining area. ICAMPS has the capability to simulate mining with multiple grids concurrently; one mine plan drawing can reference up to twenty different master grids. This feature is especially useful for multi-seam mining or where the available data justifies one or more fine grids in part of the mine and course grids elsewhere.
MineSimU also has graphical grid editing and compositing functions. Where bore hole data is relatively sparse, coarse grids are typically used. But, where more information is available, such as a longwall panel after development, a segment of the coarse grid can be refined to a small increment and the grid node parameters can be graphically edited to reflect local anomalies.

Where seam characteristics and equipment size require taking out-of-seam material, seam grids can be composited with the immediate roof and/or floor to reflect the actual quality of the shipped product.
Each grid can contain a difficulty code to reflect adverse mining conditions. This information is used to change the miner units productivity. Typical the geologist will outline problem zones on the seam map, and the planning engineer assigns the difficulty codes and productivity adjustment factors. Graphical grid editing is especially useful for creating difficulty code grids because the adverse conditions usually change abruptly and cannot be accurately represented with mathematical seam modeling techniques.
For overburden removal in surface mining, one of the grid parameters must be the overburden thickness. Where the deposit varies significantly in the vertical dimension and is thick enough to be removed in separate homogeneous layers or benches, each layer can have its own master grid. |

Calendar Features |
|
|
|
|
| |
|
Each machine can have its own calendar. The calendars are created graphically from a standard wall calendar format. Non-working days that repeat each month, such as Saturdays and Sundays, are accounted for automatically. Non-working days which vary within and between years, such as holidays and vacation shutdowns, are picked individually. The number of working shifts in each working day are also inserted in the calendar. Fractional shifts are allowed. You can also specify the number of hours worked per shift. |

AutoCad Layout Features |
|
|
|
|
| |
|
ICAMPS has two approaches to mine layout. One is to draw the mine layout using standard AutoCAD commands and later attach attribute blocks to each area. The other is to work inside the simulated mining module and use the special ICAMPS commands to draw mining areas or to create detailed projections including centerline drawings and pillar outlines.
The system can handle any reasonable mine layout. The mining areas are not limited to rectangular shapes. Designs can be retrieved from an existing drawing and copied to a new layout and repeated as necessary. The system allows the user to mirror, rotate, delete and reshape portions of existing layouts. The mine layout file can include symbols, identifying legends, text description and pointers to labor and material requirements files and other information that will affect mining costs. The figure below is an example of a mine layout containing both development and longwall panels. |

|
Where the mine operates in multiple seams, all the layouts for the individual seams are stored in one drawing. The seam layouts can be superimposed or they can be offset horizontally and/or vertically for a simultaneous unobstructed view of all the layouts. |

Sequencing Features |
|
|
|
|
| |
|
The sequence in which areas are to be mined is an interactive process that involves the user and the ICAMPS system. To assign mining areas to a machine, the user points to the areas in the order they will be mined. Color coded graphical feedback lets the user see which areas have been assigned to a machine. The user also maintains the technological sequence of mining among the machines by assigning precedences where necessary. The simulator then follows the user specified mining sequence and precedence requirements and reports the duration and cause of any delays. |

Simulated Mining Features |
|
|
|
|
| |
|
The system simulates mining with any combination of longwall, continuous/conventional miner, miner borer or roadheader. Each mining unit can have its own mining rate, either in tonnage or in linear advance. The tonnages per shift can be specified as total material remove or processed tonnage. Each miner unit can have its own calendar and production capacity. An exception routine allows the mining rate to vary from month to month. A mining area can be divided into subareas to allow more than one miner unit to work within an area and each mining area or sub-area can have its own mining rate. The system also allows the user to specify a time offset between areas for construction or to move equipment. The system has provisions to adjust the mining rate as a function of difficulty code and seam height.
The simulated production model computes the advance and average quality parameters per time period using an iterative process. The parameter estimates are exact weighted averages based on the proportion of each grid block within the area mined each period.
Most mine plans must be adjusted to meet budget requirements. Where longwalls provide the bulk of the production, the longwall schedule can be adjusted automatically by modifying the machine calendars and production rates until the target tonnage is achieved. Based on the longwall schedule, the system will adjust the development machine calendars to reflect the shifting of crews for longwall moves. The timing is then run for all machines. Normally the total tonnage will be within an acceptable margin of the budget requirements. If the schedule does not meet the tonnage criteria, the user can adjust the longwall targets and repeat the scheduling process.

Mapping & Reporting Features |
|
|
|
|
| |
|
The simulated mining module creates a master production data file which is the basis for maps and reports by time period (fiscal or calendar year), area and/or machine. Production can also be reported by surface or mineral lease. The graphical schedule output includes color coded timing maps by month,quarter, year, machine, area or quality. A suite of standard reports are provided but the master production data is also exported in spreadsheet compatible files for creating custom reports. A sample timing map is show below. The system also has various functions for solid fill, coloring, dates and other timing map cosmetics. |

Cost Reporting Features |
|
|
|
|
| |
|
The system generates cost estimates for budget purposes with spreadsheet software.To estimate future royalty payments, timing maps are matched against property lines. The output consists of production and quality reports by lessor, time period and/or type of mining.
The bills of labor and material and other cost related information from the mining areas file and the master production output file are read into a spreadsheet to create estimates of labor, material and equipment requirements by time period, mining type or other user selected criteria. The royalty, labor and material requirements are then extended at user specified prices to prepare budgets. |
