This shaft sinking headframe is a large-scale temporary steel structure system specifically designed for vertical shaft construction, offering high adaptability, efficiency, and cost-effectiveness. It is suitable for vertical shaft projects in various mines, including metal and non-metallic mines. It can be flexibly configured according to different shaft diameters, depths, and process requirements, providing a reliable aerial working and load-transfer platform for shaft excavation.
Structural Features and Working Principle:
Modular Design: Utilizes standardized steel structures with bolted connections, enabling rapid assembly, disassembly, and reuse.
Clear Load Transfer:
Vertical Loads:Head sheaves → Sheave platform → Main truss → Foundation → Ground
Horizontal Loads: Transferred and resolved through spatial trusses and bracing systems.
Multi-Functional Integration:
Sheave Platform: Centralized control hub for hoisting and suspension systems.
Muck Tipping Platform:Area for muck transfer operations.
Open Shaft Center: Ensures unobstructed passage for large equipment.
High Adaptability: Supports customization for heavy equipment (e.g., drill rigs) and specialized construction methods (e.g., freezing method, drilling method).
System Positioning: Integrates hoisting, suspension, material transfer, and protective functions, serving as a critical system for safe and rapid vertical shaft construction
| The Core Functions and Roles of a sinking headframe |
Load-Bearing and Load Transfer ◎Supports all hoisting loads (including hoisting containers, materials, dynamic loads, and impact loads). ◎Suspends underground shaft sinking equipment through the sheave wheel platform (such as hanging platforms, guide rope platforms, air ducts, pipelines, etc.). |
Guidance and Protection ◎Guides the direction of the hoisting wire rope to ensure stable operation of the hoisting container along the central axis of the shaft. ◎Provides overwind buffer height to prevent the hoisting container from impacting the hoisting machinery. |
Providing Work and Safety Platforms ◎Sheave Wheel Platform:Located at the derrick top, it supports the installation, maintenance, and inspection of sheave wheels and suspension rope arrangement.◎Waste Rock Discharge Platform: Situated in the mid-section of the derrick, it receives hoisted waste rock, unloads it, and transfers the material to mine carts or transport systems. ◎Mouth Sealing Platform: Installed at the shaft opening at the derrick base, it seals the shaft to prevent falls and acts as a safety barrier between underground and surface operations. ◎Protective Platform: Positioned below the discharge platform, it blocks falling objects to protect the shaft opening and personnel below. |
Equipment Integration and Modular Deployment
◎The derrick integrates all shaft-sinking equipment — including hoisting, suspension, ventilation, and signaling systems — into a unified layout to optimize surface arrangements. ◎With standardized and modular design, it enables quick on-site assembly. Once the mine enters permanent production, the structure can be easily dismantled or adapted, and many components are reusable. |
