Industry Examples


Maptek technology solves issues and helps mining operations improve productivity.

Dam Wall Monitoring

Problem

Continuously monitoring large areas can be expensive, and methods requiring targets are unsafe for structures such as dam walls. Operations need a solution that is flexible and easy to deploy and that provides streamlined reporting.

Solution

Maptek laser-based survey and monitoring systems provide a safe, accurate and cost-effective solution for dam wall stability monitoring. I-Site laser scanning systems capture accurate data in extremely high detail for advanced modelling and stability analysis. Sentry allows tracking of surface movement and identification of trends that can lead to potential failures.

Implementation

The extensive coverage of I-Site laser scanners provides a clear picture of surrounding areas in 3D, as well as detailed data for areas of interest. Intensity measurements allow operations to track moisture content and identify seepage for closer monitoring/as predictor of potential failure. Sentry software provides intuitive visualisation and trend analysis tools, enabling better understanding of surface movements within mines. Users can identify movement across multiple areas and report displacement, velocity and inverse velocity for safety assessments.

Digital Field Mapping

Problem

Field geologists use manual markup techniques to update geology models. This approach is unproductive and inefficient as well as being prone to inaccuracies which degrade the success of short term geological modelling, increase geotechnical risk and decrease effectiveness of short term planning and design decisions.

Solution

Digital Field Mapping capability for geologists to accurately and quickly update geological models from visible face details and add this new data directly to geological models.

Implementation

I-Site Studio on tablet PCs allows geologists to digitise structures observed in the field in their correct spatial location on laser scans. This new data is made available directly to the geological modelling process in Vulcan.

Blasthole Geological Validation

Problem

A coal mine uses drillhole geophysical data to validate its resource model and variation in strata. The downhole logs must be correctly located with respect to the as-drilled pattern data and topography to achieve accuracy goals.

Solution

Combine the gamma trace data with the validated as-drilled pattern data and surface detail graphically to enable checking and adjustment if required.

Implementation

Eureka was used to combine the as-drilled data from BlastLogic, the existing geological model, the gamma trace data and I-Site laser scans of the bench surface. This showed, with very high accuracy and in 3D, the geological correlation of the measured data with the predicted data, and provided information for adjusting and updating the geological model in Vulcan. Blast drilling and loading was improved and dilution and coal loss materially reduced.

Production and Design Reconciliation

Problem

How to measure, reconcile and report on blast profile, partially dug blocks, toes and crest positions and stockpiles accurately to track production and accuracy, while maintaining safety and productivity of mining fleet and report results to allow management decision support to mining operations.

Solution

Laser scanning of production areas feeding accurate, timely surface data into the geological and design models for the mine for fast, reliable reconciliation.

Implementation

I-Site laser scanner deployed to capture all 3D survey data for modelling in Vulcan and comparison against mine plans and designs. Production status can be reconciled and grade control / reserving against block models can be undertaken.

Coal Tracking System Calibration

Problem

A customised system for tracking production and movement of coal throughout an integrated supply chain requires parameters such as accurate, real world locations, angles and distances to be recorded. Site surveyors are not able to conduct this work.

Solution

Outsource the system configuration and calibration to a solution provider with the measurement capability and the expertise to coordinate this effort to ensure efficiency goals for the project match those set for the mine development.

Implementation

Maptek implemented a specific design for modelling functionality to ensure it matched on-site facilities for coal tracking. The system allows the operation to monitor the quality of coal through its various mine sites and facilities. It is already in use at some sites within the operation, where it reports on quality levels and trending qualities in pseudo real-time. I-Site laser scanning can add value by ensuring an accurate monthly baseline for stockpiles and calibration of the system.

Strategic Optimisation

Problem

Operations are using three to four different products to reserve, schedule and optimise their operations. There is potential for mishandling of data when swapping between programs. Spreadsheet or fleet calculator approaches mean the choice of waste destination and associated costs are pre- or post-scheduling decisions, with significant implications for budgets and operating costs.

Solution

Streamline the process by using one provider for reserving, optimisation and waste haulage for increased productivity gains. Lower maintenance costs by switching to one solution provider.

Implementation

Maptek Evolution acknowledges the importance of haulage optimisation to minimise haulage costs. Reserving is handled in Vulcan, and integrated scheduling and waste optimisation with Evolution creates a seamless workflow from block model to production plans. Optimal haulage routes can be achieved and mine planners can make informed, confident decisions regarding scheduling that reduce costs and maximise the resource.

Geotechnical Analysis

Problem

How to make the most of geotechnical data captured by a laser scanner in mine planning software without disrupting existing historical geotechnical database.

Solution

Use dedicated geotechnical analysis software in conjunction with mine planning software to complete analysis and automatically update the geotechnical database.

Implementation

Export the geotechnical database from Vulcan and import into I-Site Studio Geotechnical Module. Access data straight from the laser scan and use to identify areas of structural weakness that will affect mine planning and operational decisions. The Vulcan geotechnical database is automatically updated with new information while maintaining data integrity.
