Mining Backfill System Solution
Intelligent Remote Centralized Emulsion Supply Solution for Underground Coal Mines
Engineered Paste and Tailings Backfill for Underground Mining
GOLDDRILL provides integrated mining backfill system solutions for underground coal and metal mines, converting gangue, tailings, and other solid waste into engineered backfill materials.
The system supports underground mine safety, resource recovery, surface waste reduction, and more sustainable mining operations. By using waste materials for underground filling, mines can reduce surface disposal requirements while improving the utilization of available mineral resources.
GOLDDRILL integrates crushing, material batching, mixing, high-pressure pumping, pipeline transportation, and process control into a coordinated backfill solution. The system is designed to support goaf filling, stope backfill, surface subsidence control, and underground tailings storage through a controlled and repeatable process.
Engineered for continuous underground operation, the system combines wear-resistant backfill pipelines, high-pressure pipe couplings, mining pumps, and modular processing equipment. Each system can be configured according to the mine’s geology, backfill material, required capacity, transportation distance, and underground layout.
Industry Challenges
Underground mining generates large volumes of gangue, tailings, and other solid waste that must be handled and disposed of efficiently.
Mining operators commonly face the following challenges:
-
Surface land occupation and environmental pressure caused by waste accumulation
-
Goaf stability risks, including roof movement and surface subsidence
-
Limited resource recovery when reserves near goafs cannot be safely extracted
-
Inconsistent backfill quality caused by manual or semi-mechanized production methods
-
High operating costs and technical difficulties associated with long-distance paste transportation
-
Limited centralized monitoring and process control across the backfill system
Our Solution
Remote Centralized Backfill for Underground Goaf Filling
GOLDDRILL integrates the main stages of the underground mine backfill process, from material preparation and automated batching to mixing, high-pressure pumping, and pipeline delivery.
The system is configured according to the specific requirements of each mining project, including:
-
Backfill material type, such as paste, quasi-paste, or cemented backfill
-
Required production capacity and material throughput
-
Pipeline transportation distance and elevation difference
-
Slurry concentration, particle size, and material properties
-
Underground operating conditions and pipeline routing
-
Required level of automation, monitoring, and process control
This approach enables mining operators to select the appropriate equipment, pipeline components, pumping capacity, and control functions for the intended paste backfill system or tailings backfill system.
Main System Functions
Converts gangue, tailings, and other solid waste into engineered backfill material for underground filling. This helps reduce surface waste accumulation and supports more efficient use of mining by-products.
Controls the proportion of aggregate, tailings, cement, and other additives to produce consistent backfill material. Accurate batching and mixing support the required backfill strength, flowability, density, and curing performance.
Transfers paste, quasi-paste, and cemented slurry over long distances to underground stopes, goafs, or designated filling areas. Pump selection is based on material characteristics, required flow rate, pipeline length, and operating pressure.
Uses matched wear-resistant steel pipes, high-pressure couplings, elbows, tees, and other fittings for demanding slurry transportation conditions. Pipeline materials and components can be selected according to slurry concentration, particle size, pressure, and expected wear.
PLC systems, pressure sensors, flow sensors, and optional SCADA platforms can be integrated to monitor key operating parameters, equipment status, and pipeline conditions.
Modular equipment and suitable pipeline connections support system installation, inspection, component replacement, and routine maintenance. Properly arranged pipeline sections and isolation points can also help reduce maintenance time.
