4 Major Technology Development Trends in Underground Mining Support Systems

2025-02-28

In some emerging market countries, the demand for mining support systems is increasing due to lagging infrastructure construction and other reasons.

In particular, with the promotion of China's "Belt and Road" strategy, more underground mining support systems made in China are being applied to developing countries.

Relevant data show that some mines in Australia have increased the monthly tunneling speed to 350 meters with the help of intelligent integrated excavation and anchoring technology, which reflects the importance of underground mining support systems.

In the United States, the proportion of casualties in mine top accidents using advanced support technology has decreased by about 20%, which has had a disruptive impact on the mining industry.

Due to the improvement of mining efficiency brought by technology, German/Chinese mining equipment has received a large number of orders in the international market. The mining support system of China Tianlong Company, with its simple structure and convenient operation, provides a new solution for mining support in complex geology.

As a leading fastener manufacturer in China, Tianlong provides high-quality Mining support system, bolts and nuts, auto parts, resin cartridge wholesale/OEM manufacturing services, which are widely used in construction/mining/railway and automotive industries.

If you are a purchaser of a mining support system, how to purchase equipment that meets future development trends? This article describes in detail the five development trends of mining support systems.

1. Underground mining support systems will be more automated and intelligent

The mining industry is not only an industry with huge capital investment, but also has extremely high labor costs and high safety risks.

In order to further reduce costs and improve safety, many mining support systems will use more automated and intelligent systems to reduce manual operations to reduce the risk of work injuries and deaths.

Moreover, since the probability of error in manual operations is higher than that of AI intelligence, this basically determines that future mining equipment will rely more on modern technology.

Automation and intelligence of mining support systems:

Automatic frame shifting: Through electro-hydraulic control systems and sensors, the hydraulic supports of the coal mining face can automatically complete the frame shifting action according to the position of the coal mining machine and the progress of coal mining without manual operation.

Remote control: Using remote control technology and 5G communication, workers can remotely control the anchor drill to drill holes and install anchors.

Automatic docking: The support equipment can automatically complete the pipeline docking and support connection.

Surrounding rock state monitoring: Use sensor networks to monitor the displacement, stress, and strain parameters of the surrounding rock.

Geological condition identification: With the help of geological radar and three-dimensional laser scanning technology, faults and broken zones can be identified in advance.

Work environment monitoring: Use gas sensors and dust sensors to monitor the gas concentration, dust content, temperature and humidity in the mine in real time.

Intelligent solution generation: Based on artificial intelligence algorithms and big data analysis, support solutions are automatically generated according to geological conditions.

Real-time optimization and adjustment: When the surrounding rock pressure increases, the length or density of the anchor rod is automatically increased.

Risk assessment and early warning: Use machine learning algorithms to establish a risk assessment model, evaluate the stability of the support system, and warn of risks in advance.

Intelligent warehousing and distribution: Establish an intelligent support material storage system to realize the automatic storage, inventory and distribution of support materials.

2. Innovation of underground mining support materials

1. Ultra-high strength plastic support net

A coal mine in China uses an ultra-high strength plastic support net. In the past, the roof support of the underground tunnel of the coal mine used metal mesh, which was heavy and difficult to install. The new ultra-high-strength plastic support net has longitudinal and transverse ribs connected, and has good integrity.

2. Galvanized hexagonal chain link fence

In response to the problems of quartz vein-type ore bodies and high surrounding rock classification, a Chinese manufacturing company successfully developed galvanized hexagonal chain link fence support materials to reduce the labor intensity of workers. Experts have repeatedly demonstrated that the support cost of this material is 43.84% lower than that of metal mesh, and the support efficiency is increased by 43.39%.

3. NPR anchor steel

The NPR constant resistance large deformation anchor cable developed by a Chinese expert is suitable for soft rock geological conditions. The yield strength of NPR anchor steel is about 1000 MPa, which is more than twice that of ordinary threaded steel, and it is not easy to have local deformation problems.

3. Underground mining support systems Equipment integration

In the future, underground mining support systems equipment will become larger and heavier to improve the carrying capacity of the equipment. For example, large mining height hydraulic supports and powerful anchor drills can greatly improve mining efficiency.

In addition, underground mining support systems equipment will gradually achieve integrated excavation and anchoring, and integrated mining, support and transportation, forming an integrated engineering solution for excavation, support and transportation processes.

4, the safety performance of mining support systems continues to improve

The safety improvement of mining support equipment has always been a priority for technicians.

This is because, in deep mines (depth > 1-1.5 kilometers), the risk of support failure caused by high rock stress increases exponentially with increasing depth.

Related accident cases

Short wall mining accident in the United States: The support used in the mine area used a 4-foot full-length resin anchor, but the roof thickness exceeded 5 feet, and the intersection became wider due to the turn. No additional support was provided for the roof, which eventually caused the accident.

Brunswick mine accident in Canada: Due to installation problems, the anchor support in some areas of the mine could not provide sufficient anchoring force during the mining stage, resulting in a roof collapse accident.

In the future, underground mining support systems will adopt more complete safety monitoring systems to make the monitoring data more accurate, and have more intelligent safety warning mechanisms to improve the speed of rapid response and protect the lives of workers.

In addition, the design of underground mining support systems will also adopt more advanced safety technologies, add anti-fall and anti-slip devices, overload protection devices, and automatic spray dust reduction devices to reduce the risk of accidents.
