Mine hoisting systems are a critical component of the infrastructure of any mining operation. Hoisting installations ensure the safe and efficient transportation of personnel, materials, and extracted minerals between underground levels and the surface.
IGEA — Institute of Mining Electrical Engineering and Automation — develops and implements modern mine hoist systems, control systems, braking systems and monitoring solutions, ensuring safe and efficient operation of mining enterprises.
IGEA engineering solutions integrate mechanical hoisting equipment, electric drive systems, industrial automation and safety systems, forming complete mine hoisting complexes for modern mining operations.
Purpose of Mine Hoisting Systems
Mine hoists perform several key functions in underground mining operations:
- transportation of personnel in the shaft
- hoisting of ore and rock to the surface
- transportation of equipment and materials
- movement of loads between underground levels
- emergency evacuation of personnel
The reliability and safety of the hoisting system directly affects the operational efficiency and safety of the entire mine.
Integrated Hoisting Solutions
IGEA provides turnkey mine hoisting system solutions, including engineering design, manufacturing, and commissioning of equipment.
A typical hoisting system supplied by IGEA may include:
- mechanical hoisting machine
- electric drive and high-power motors
- variable frequency drives (VFD)
- hoist control system
- motion monitoring and protection systems
- braking system for mine hoists
- hoist parameter recording system
- electrical distribution equipment
- diagnostic and monitoring systems
An integrated engineering approach ensures high reliability of mine hoisting operations and optimal compatibility of all system components.
Hoist Control and Motion Monitoring System
The hoist control system is responsible for ensuring safe operation of the mine hoist and preventing hazardous situations.
The system provides:
- monitoring of hoist speed
- monitoring of cage or skip position in the shaft
- control of end-of-travel limits
- generation of protective speed diagrams
- overload protection
- automatic shutdown of the hoist in emergency conditions
IGEA control systems are built on industrial microprocessor controllers and can be integrated into the mine's dispatching and SCADA systems.
Braking Systems for Mine Hoists
The braking system is one of the most critical safety components of a mine hoisting installation.
Hoisting systems may use:
- hydraulic disc braking systems
- radial shoe brakes
- pneumatic braking systems
The braking system ensures:
- service braking of the hoist
- emergency braking
- monitoring of braking pressure and system status
- reliable operation under heavy-duty mining conditions
Hoist Parameter Recording System
Modern mine hoisting systems can be equipped with a hoist parameter recorder for operational monitoring and safety analysis.
The recorder allows:
- continuous recording of operational parameters
- logging of emergency events
- monitoring of operator actions
- analysis of hoist operating conditions
- long-term storage of operational data
Such monitoring systems significantly improve operational transparency and industrial safety.
Modernization of Existing Hoisting Systems
IGEA performs modernization of existing mine hoisting machines and control systems.
Modernization projects may include:
- replacement of legacy electric drives with variable frequency drives
- upgrading braking systems
- installation of microprocessor control systems
- integration of hoist parameter recording systems
- implementation of digital diagnostics and monitoring
Modernization increases equipment reliability, extends the service life of hoisting installations and reduces operational costs.
