    Special Backfill Tunnel End Support with function for compact the backfill material in underground coal mine

    ■ Product Features

    ● With the development of coal mining technology, the requirements for safety, high yield, and high efficiency in fully mechanized mining faces are increasingly higher. The issue of tunnel end and advance support has become a focus of attention for mining operators. Simultaneously, tunnel end and advance hydraulic supports are also key equipment for achieving automated working faces. The tunnel end and advance hydraulic supports developed by our factory have realized the mechanization of tunnel end and advance support. The project "Research and Design of Tunnel End Hydraulic Support for Backfill Mining Faces" completed for Xingtai Coal Mine was awarded the Third Prize for Scientific and Technological Progress by the China National Coal Association; the project "Research and Application of Tunnel End Hydraulic Support for Top-Coal Caving Mining Faces" completed for Dongpang Mine achieved safe and efficient mining in top-coal caving faces. This project has also passed the technical evaluation organized by the Hebei Province Achievement Transformation Center. Advance supports currently come in various forms such as two-column type and transverse type, meeting the personalized needs of users.

     

    Features:

    The supports must conform to the patterns of mine pressure manifestation during backfilling operations.

    The supports must possess sufficient load-bearing capacity to control roof subsidence.

    The supports must exhibit no weak points in their load-bearing structure.

    The front and rear spaces of the supports must be independent, enabling parallel operations.

     

    Supporting strength: 0.5MPa
    Working resistance: 6000 kN
    Support height: Minimum height 1.5m Maximum height 3.2m
