Using waste rock as backfill in mining operations can have several economic advantages that can lower overall mining costs and effectively reduce the cutoff grade needed to make a mining project viable. Here are some key points explaining how this works:
1. Reduction in Waste Management Costs:
- Minimizing the Need for Disposal: By utilizing waste rocks as backfill, mining companies can avoid the costs associated with transporting and disposing of waste material. This reduces the need for waste rock storage facilities, which can be expensive to construct and maintain.
- Maintaining Land Use: By backfilling pits with waste rock, companies can minimize land use and environmental impact while potentially avoiding regulatory costs related to waste management.
2. Decrease in Land Rehabilitation Costs:
- Stabilization of Mine Sites: Backfilling helps stabilize the mine site, reducing the long-term costs associated with land rehabilitation and remediation once mining operations cease.
- Easier Rehabilitation: Using waste material for backfilling can lead to more straightforward rehabilitation strategies, since the mined land can be restored more easily if it has already been filled and stabilized.
3. Improved Resource Recovery:
- Increased Extraction Efficiency: Backfilling can allow for more efficient resource recovery. When waste rock is managed properly and used to support mine workings, it can create opportunities to mine lower-grade ore which, otherwise, would not have been economical to extract.
- Optimizing Mining Operations: By using waste rock to provide structural support, mining operations may be able to operate in a more flexible manner with larger mining sequences and lower operational risks.
4. Lower Transportation Costs:
- Cutting Haulage Needs: Using waste rock locally reduces the need to transport backfill material from other sites, leading to notable savings on transportation costs. These savings can further decrease the overall operational costs of mining.
5. Economic Impact on Cutoff Grade:
- Redefining Economic Viability: The reduction in overall operational and management costs allows for a reassessment of the cutoff grade, which is the minimum grade at which a particular mineral can be economically mined. Lower mining costs enable the feasibility of mining lower-grade ores, thus enhancing the overall resource base that is economically extractable.
- Increased Flexibility: By lowering the cutoff grade, mining companies can decide to extract ores that were previously considered uneconomic, thus increasing the total recoverable reserves and potentially improving the mine's overall profitability.

🌏 How can we more effectively deal with mining waste? – Backfill design and using what’s available
🌏 Whether found during exploration or created from extraction, mining voids can pose a danger. Backfilling these voids addresses structural integrity and geographical stability concerns, reducing the risk of cave-ins, landslips, and sinkholes. When correctly implemented, backfilling can also reduce the risk of acid rock drainage by blocking the spread of contaminated water.
🌏 Waste materials can be used for backfill, like rocks, sand, coarse tailings, and paste tailings. This recycling keeps tailings storage facilities from getting too full and it’s an effective way of reusing junk in a constructive way. However, this isn’t just filling holes willy-nilly. There are many considerations to backfilling effectively and safely.
🌏 Backfill design falls into three general categories:
🌐 Hydraulic engineering, which deals with pipes and fluid flow.
🌐 Geotechnical engineering, which deals with rockmass structures
🌐 Process engineering, which deals with plant design and control
🌏 How does your organization build backfill models? How are these systems monitored and verified? What are some ways in which we can improve current backfill models? Let us know in the comments!

🌟 Hydraulic Fracturing Technology for initial roof caving in coal mining by CCTEG
🚀 At the Jinjitan Coal Mine's 110 and 111 top coal caving working faces, we made a successful hydraulic fracturing process for initial roof caving, addressing the challenge of initial roof caving in top coal caving faces.
🛠️ The project employed a novel technique combining "conventional short-hole hydraulic fracturing" with "directional long drilling hole hydraulic fracturing." This approach not only solved pre-splitting in the coal seam roof but also addressed the problem of controlling the range and intensity of overburden movement caused by the transformation of large rock masses into smaller ones in the roadway surrounding rock. The short-hole drilling totaled 2,435 meters, with 724 segments fractured, while the long-hole drilling reached 891 meters, with 18 segments fractured.
🔍 The comprehensive assessment of the multi-dimensional hydraulic fracturing in weakening the overburden showed that all indicators met the expected outcomes. When the working face advanced 34 meters, the basic roof pressure occurred, indicating excellent initial roof caving results.
💡 This new technique of multi-dimensional hydraulic fracturing for initial roof caving represents a green, environmentally friendly, and efficient technology for hard roof pressure relief. It offers a novel alternative to traditional explosive blasting techniques for cross cutting and advanced pre-treatment of dynamic pressure disasters. This innovative technology provides a solid technical guarantee for mine safety production and leads the way in advancing mine dynamic disaster prevention towards proactive pre-treatment, regional multi-dimensional pressure relief, and safe, green, and efficient development.

Safety and Risks:
UG Mines: Higher risks due to confined spaces, potential collapses, and gas hazards.
Open Cast Mines: Risks include landslides and machinery accidents, but generally easier to manage.
Environmental Impact:
UG Mines: Lower surface impact but potential subsidence and groundwater issues.
Open Cast Mines: Significant surface impact, requiring extensive reclamation efforts.
Cost:
UG Mines: Generally more expensive due to complex infrastructure and safety measures.
Open Cast Mines: Lower cost per ton of material extracted due to simpler operations and economies of scale.
In summary, both underground and open cast mining have their own sets of advantages, challenges, and impacts, making the choice of method dependent on the specific conditions of the resource being mined and the surrounding environment.

Ground freezing is a ground improvement technique in which subsurface pipes are installed
and a refrigerated brine (e.g., calcium chloride and water) is circulated through the pipes so that
the ground is literally frozen. The hardened, frozen soil can then be excavated using
conventional mining techniques such as SEM or left in place to support adjoining construction
activities.
The "Funnel Effect".
Many mines that transition from open-pit to underground have to ensure their pump stations have enough capacity to cater for high rainfall and rapid ice melt events.
Our GSB Self-Balancing multistage pump for dirty water is the pump-of-choice for these types of applications as they can handle up 1800 m3/hour, or 8000 GPM, at 1600 m or 5200 ft.. All while running at a hydraulic efficiency of up to 83 %, ensuring the power demand stays low.
Open pits are having to transition to underground operations to reach the deep level reefs.
With this transition, comes the need to dewater the mine. Giffen Consulting, in collaboration with Scamont Engineering , boast many years of deep-level underground mine dewatering experience.
This has led us to develop products to suit any underground mine dewatering application, from low volume, high head to high volume, high head applications for both clear and dirty water management.
We are well-positioned to assist any mining operation with their dewatering requirements, as they transition from open pit to underground. Reach out to us if you need assistance with your operation.
