Mining cables produced by CN CABLE guarantee safe and efficient underground production

As a core component of mine electrical system, the performance of mining cable is directly related to the production efficiency and safety level of the mine. In this paper, we will discuss the challenges faced by mining cables in practical application, and put forward optimisation strategies from various aspects such as selection, laying, connection, maintenance, etc., aiming to improve the service life of mining cables, reduce the maintenance cost, and guarantee the safe and efficient production in mines.

Mining environment is complex and variable, high temperature, high humidity, high dust, vibration, corrosion and other harsh conditions on the performance of mining cables put forward a serious challenge. Traditional mining cables are often used in the process of aging, insulation damage, loose joints and other problems, not only affecting the normal production of the mine, but also the existence of triggering fires, explosions and other security risks. Therefore, optimising mining cables to improve their reliability and service life is an important part of ensuring safe production in mines.

Optimisation strategy of mining cable

1. Selection optimisation

· Selection according to the load: Considering the electrical load in different areas of the mine, select the cables with suitable conductor cross-sectional area and insulation level.

· Adapt to the environment selection: for the high temperature, high humidity, high dust and other characteristics of the mine, select the cable with high temperature, humidity, abrasion, corrosion resistance and other properties.

· Considering the laying method: according to the laying method (overhead, trench, tube, etc.), select the cable with corresponding structural characteristics.

2. Optimisation of laying

· Reasonable planning of routes: Avoid cables crossing high-temperature areas or mechanically damaged areas to reduce the possibility of cable damage.

· Firm fixing: Use suitable fixing methods to ensure that the cable does not slacken and prevent insulation damage caused by vibration.

· Protective measures: Add protective layers or sleeves in areas prone to abrasion or corrosion.

3. Connection optimisation

· Choose suitable connection methods: Use heat-shrinkable sleeve connections or crimp connections to ensure that the connections have good electrical properties and mechanical strength.

· Regular Inspection and Maintenance: Regularly inspect the connections to detect and deal with problems such as loosening and oxidation.

4. Maintenance optimisation

· Establishment of inspection system: Regular inspection of mining cables, timely detection and treatment of faults.

· Adopt advanced detection technology: Use infrared thermal imaging, partial discharge detection and other technologies to conduct online monitoring of cables.

· Formulate maintenance plan: Formulate scientific and reasonable maintenance plan according to the operating condition of cables.

5. Material optimisation

· New materials: Adopt special materials such as high temperature resistance, corrosion resistance, flame retardant, etc. to improve the performance of the cable.

· new structure: research and development of armoured cables, shielded cables and other new structures to enhance the protective capacity of the cable.

Optimisation of mining cable development trend

· Intelligent: Combined with the Internet of Things, big data and other technologies, real-time monitoring of the state of mining cables and intelligent maintenance.

· Digitalisation: establish a mining cable information management system to achieve digital management of cable assets.

· Greening: Adopting environmentally friendly materials and processes to reduce the impact of mining cables on the environment.

Optimising mining cables is an important means of improving mine safety. By comprehensively applying various measures such as selection optimisation, laying optimisation, connection optimisation, maintenance optimisation and material optimisation, the service life and reliability of mining cables can be effectively improved, maintenance costs can be reduced, and safe and efficient production in mines can be guaranteed. With the continuous progress of science and technology, the optimisation technology of mining cables will be further developed to provide more powerful guarantee for the safe production of mines.Welcome to consult CN cable's coal mining cable, 24 hours online for you!
