MineGraphics provides an enhanced visualization of current activities within the mine for dispatchers, supervisors, and other personnel in the central office. With MineGraphics, users can:

  • Visualize equipment movement in real time
  • Simultaneously illustrate mine locations and tunnel networks in both Section View and Plan View
  • Display .dxf files from modeling software as separate layers
  • Filter by elevation, equipment types, location types, and more

Time Tracking

The Time Tracking module enables dispatchers to monitor equipment and location activity, utilization, and availability. The system utilizes Status Tracking and Equipment Cycle Tracking to produce a complete time usage model.

Status Tracking, the primary method of Time Tracking, enables operators to quickly alert dispatchers of changes to equipment or location status.

Equipment statuses are defined as:

  • Ready – Operator is logged in and the equipment is currently operating
  • Delay – Operator is on-board the equipment but the equipment will not be operating for a known period of time
  • Standby – Equipment is available for use but is not currently being operated
  • Down - Unavailable for work

Statuses can be further broken down into reason codes, and then mapped into time categories for reporting purposes.

Equipment Cycle Tracking is used to calculate productivity based on repeated actions of equipment. The equipment’s operating time is separated into several distinct stages, which are then linked together to form a cycle. For example, the following stages: Travel Empty/Full, Queue, Load, and Dump; form a haulage cycle for a haul truck.

Material Management

Material Management maintains material quantities and qualities between survey intervals in real time. Following a blast, ore control personnel can update material inventories as required. The system will then automatically track material inventory levels, grades, and densities as material is added or removed from a given location.

Track critical operational parameters such as tonnage, volume, and grade, for material movements between all locations, including:

  • Headings
  • Stopes
  • Stockpiles
  • Ore Passes
  • Draw points
  • Crushers

Locations Management

The Locations module enables Dispatch Engineers to create hierarchically-structured (parent/child) lists of the locations within your mine. The hierarchical locations structure provides the operator with an intuitive navigation tool that presents contextually-relevant information based on the equipment‘s current tracked position.

Equipment Control

Location Reason Code

The optional Location Reason Code module enables operators and dispatchers to set the status and reason code for work locations. Location Reason Code integrates with Task Management to enable process execution whereby the configured mining cycle can be automated.

For example, when an LHD operator has completed a task for cleaning a working face, the status and reason code of the face will automatically change to: Delay – Drilling, development. This signifies that the location is now in a delay state until the development drill arrives. In parallel, this status and reason code change will generate a task for the development drill to work at this face. Allowing the operators to advance a mining process provides an efficient means to task automation. Task lists are not updated while working in offline mode.

Benefits of the Location Reason Code module include:

  • Ability to quickly inform operators of new tasks as location conditions change
  • Allowing operators to advance stages of a work cycle based on the status of the working face
  • Reducing reaction times to draw point hang ups, ore pass blockages, and other delays at the working face

Draw Card Management

The optional Draw Cards module enables dispatchers to distribute a Block Cave draw point extraction plan to LHD mobile field computers. Use the Draw Cards module to:

  • Present LHD operators with individual assignments according to the draw point extraction plan
  • Simultaneously monitor extraction progress for all active draw points
  • Provide supervisors with a visual representation of any deviation from the original extraction plan
  • Maintain the integrity of the extraction plan by carrying any unfinished work over to the following shift

Safety Management

Equipment Prestart Checklist

The optional Equipment Prestart module ensures operator accountability for assessing equipment condition before use. The DISPATCH Underground system automatically records configurable PASS/FAIL information for Equipment Prestart checklist items. Generate exceptions for specific failed items, and review the Prestart history for each unity on a shift-by-shift basis.

Operators verify Equipment Prestart items on their mobile devices as part of the logon sequence. If a failed item falls within the “Do Not Operate” or “Contact Dispatcher” section, an exception notification displays on the dispatcher’s screen. A failed “Do Not Operate” item, such as: STEERING – DO NOT OPERATE! also generates an exception message for the dispatcher.

Location Checklist

The optional Location Checklist module ensures operator accountability for assessing workplace conditions before commencing work at a specific location.

Dispatchers use the module’s desktop application interface to create user-defined checklists for specific work locations. Upon arrival at a location, operators use their mobile devices to assign PASS or FAIL status to each item on the checklist. The PASS/FAIL information is automatically recorded in the DISPATCH Underground system. Exceptions can be generated for specific failed items.

Failed items that fall within the “Do Not Work” or “Contact Dispatcher” section automatically generate an exception notification which displays on the dispatcher’s screen.
