Coal mine nuts

2025-12-08

Coal mine nuts are specialized fasteners designed for harsh industrial environments such as coal mines. Their core function is to provide stable and reliable connections for coal mining machinery, equipment, and support structures. These nuts are typically made of high-strength alloy steel and possess excellent tensile, compressive, and corrosion resistance properties to adapt to the special environments in coal mines, such as dampness, dustiness, and intense vibrations.

Technical Characteristics and Manufacturing Process

The design of coal mine nuts must strictly adhere to coal mine safety standards, such as the MT/T series standards, to ensure their reliability under extreme conditions. The manufacturing process includes heat treatment, surface treatment (such as galvanization, Dacromet coating), etc., to enhance wear resistance and rust prevention capabilities. Some high-end products also adopt self-locking designs, using elastic gaskets or thread deformation technology to prevent loosening and reducing maintenance frequency.

Application scenario

Support system: Used to fix support equipment such as hydraulic supports, anchor rods, and anchor cables, ensuring the stability of the roadway.

Transportation equipment: Tightens the transmission components of belt conveyors and scraper conveyors to prevent loosening caused by vibration.

Mining and excavation machinery: Connects key components of drilling machines and coal mining machines, bearing high-intensity impact loads.
