Underground safety, productivity and profitability
In the world of underground mining, inaccessible areas such as stopes and ore passes are crucial areas that directly determine the shift and monthly productivity. Cavity Monitoring Systems (CMS) provide limited visibility into these dangerous areas but are constrained by access. Digital Terrain continue to pioneer Autonomous LiDAR enabled drone technology with solutions that offer rich capabilities in mapping, monitoring, and managing underground environments.
Key benefits in underground mining include:
1. Precise 3D Mapping:
LiDAR technology enables high-resolution 3D mapping of underground environments with remarkable accuracy. By emitting laser pulses and measuring the time it takes for them to return, LiDAR scanners can create detailed point clouds that accurately represent the terrain, infrastructure, and geological features of underground workings, including stopes and inaccessible areas.
2. Enhanced Safety:
One of the most significant benefits of Autonomous Drone technology in underground mining is its contribution to safety. By operating within the protective barricades and barriers comprehensive data on the conditions of underground workings, LiDAR derived data helps identify potential hazards such as unstable ground, roof collapses, or hangups and blockages. This allows mining operators to take proactive measures to mitigate risks and ensure the safety of employees.
3. Improved Planning and Design:
LiDAR-generated 3D maps facilitate better planning and design of underground mining operations. By accurately capturing the geometry and topography of stopes and voids, mining engineers can optimize the layout of infrastructure, plan drilling and blasting activities more effectively, and minimize waste generation. This leads to increased operational efficiency and reduced costs.
4. Monitoring and Management:
LiDAR enabled drones enables continuous monitoring of underground environments, providing valuable insights into ground movement, rock stability, and infrastructure integrity. By comparing successive LiDAR scans over time, mining operators can detect changes in the underground environment, assess the effectiveness of ground support measures, and identify areas requiring maintenance or remediation.
5. Remote Inspection and Exploration:
Drones integrated with LiDAR technology offers a non-intrusive means of inspection and exploration. By deploying LiDAR-equipped drones or robotic platforms, mining operators can autonomously survey inaccessible areas, gather valuable data, and make informed decisions where only a few short years ago it was near impossible to gain insights into these underground areas.
6. Augmented services vs Do it yourself (DIY)
Most mines have already invested in drone and LiDAR technology to some extent, but have been disappointed with the results or have suffered lost and damaged equipment. There are many reasons for this including
- Personnel changes mean constant re-training
- Operators only gain limited and site-specific experience. This makes them unprepared for difficult scenarios that might develop. Infrequent use almost always results in loss and damage of expensive equipment
- Collecting the data is only half the job. Processing the data collected requires specialist skillsets. Processing and interpreting collected data is extremely heavy on compute and is very data intensive because of the sheer size of datasets.
- Processing turnaround is crucial. Operators often do not have sufficient time to learn and experiment with processing software, techniques and settings for optimal results – all with time sensitivity to inform operational decisions.
- Historical data collected over time is lost or not managed correctly
- Specialist shaft, lighting and other sensor attachments are not easily available but are critical for success

An accurate Digital model for the main decline of an underground mining operation is important and offers valuable benefits for mining companies and operators. From optimising resource extraction to enhancing safety protocols, the meticulous mapping of main declines serves as a cornerstone for efficient and sustainable mining practices. Let's explore some of the key advantages and benefits: 1. Enhanced Safety Protocols: Accurate mapping of the main decline enables mining companies to identify potential safety hazards such as unstable ground conditions, geological faults, or reinforcement movements. By proactively addressing these risks, mining operators can implement robust safety protocols, reducing the likelihood of accidents or incidents and ensuring the well-being of personnel working in the area. 2. Improved Resource Optimization: Mapping the main decline provides valuable insights into the geological characteristics and mineralization patterns of the surrounding ore body. This information allows mining engineers to optimise resource extraction strategies, including the design of mining methods, stope layouts, and ore handling systems. By maximising resource recovery while minimising waste, mining companies can enhance operational efficiency and profitability. 3. Enhanced Operational Planning: Accurate mapping of the main decline facilitates comprehensive operational planning, including scheduling of drilling, blasting, and extraction activities. By visualising the spatial layout of the decline and associated infrastructure, mining operators can optimise workflows, streamline logistics, and minimise downtime, leading to improved productivity and cost-effectiveness. 4. Facilitates Infrastructure Development: Detailed mapping of the main decline provides essential data for the design and construction of infrastructure such as ventilation systems, service lines into the operation, and support structures. By accurately assessing the spatial constraints and geological conditions of the decline, mining engineers can optimise the layout and configuration of infrastructure elements, ensuring efficient operation and maintenance throughout the mine's lifespan. 5. Supports Regulatory Compliance: Mining companies are subject to stringent regulatory requirements governing safety, environmental protection, and resource management. Accurate mapping of the main decline helps ensure compliance with these regulations by providing comprehensive documentation of underground workings, geological features, and safety measures undertaken. This enables mining operators to demonstrate due diligence and accountability to regulatory authorities and stakeholders. Mapping the main decline of a mining operation is a strategic imperative that yields a multitude of benefits that Digital Terrain know and understand.

Underground mining is a harsh environment to operate in, where the next decision can be the difference between continued progress or productivity halting delays. Often it is the ‘gut-feel’ or ‘intuition’ that results in pulling Lever A as opposed to Lever B, but when it is estimated that the average adult makes 35,000 decisions a day (Sollisch 2016), it is clear that not all of these can possibly be the optimal solution all of the time. Traditionally, data collection has been a lagged, cumbersome process, fraught with inaccuracies (poor radio communications, misplaced/damaged/destroyed paperwork), double handling (horizontally integrated systems) and delays (data entry occurs progressively by site administration on the following shift for the one preceding it). However, with the advent of digitization, this narrative is rapidly changing. Real-time data collection and analysis empower stakeholders to access accurate and timely information, enabling them to make informed de cisions on the fly. Coupled with Digital Terrain’s RDI-WRS Wireless Repeater System ( https://www.digitalterrain.io/revolutionising-underground-mining-with-wi-fi-mesh-technology ), Simbio PLOD can present decision makers within your business the information they need to execute your plans and achieve your goals. Digital Terrain‘s Simbio Core Suite (SCS) puts frontline personnel at the heart of their solution. Operators are empowered to capture their own data, in real-time, through the use of the Simbio PLOD app (available on Android and iOS). Each operator logs the progress of their shift as they complete their assigned tasks (using Simbio’s PLAN module) including Task Workplace Inspections (Take 5’s, Stop and Thinks, Safe Stops etc), Prestarts, Hazard Forms, Productive Time, Downtime, Maintenance Faults, Trigger Action Response Plan (TARP) workflow escalations and more. The Digital Terrain team is committed to ensure that your operation can hit the ground running from Day 1.
