Application of Flexible Mine Grid in large mining height and large cross section withdrawal channel

Application of Flexible Mine Grid in large mining height and large cross section withdrawal channel

Base on how to protect the safety of the personnel and equipment, to reduce the equipment removing time of the coal mning face and to improve the continued rate of the mining block is one of the key issues to build the modernized coal mine. Taking the removing if the Y120201 coal mining face in Yangchang Wan Mine as the project background, base on the feasibility analysis, the paper in detail introduced the successful application experiences of the flexible MineGrid to the gateway contruction to remove the large and heavy equipment from the high cutting coal mining face. With the comparison on the projects, the application of the support material would have more obvious safety and economice benefits than the previous steel mesh support technique. The successful application of the technique discovered a new access to create safety and rapid removing conditions for the high cutting large and heavy mining equipment and would have certain value for the promotion application

Geosky® Mining Grid is made of high-modulus and high tenacity polyester (PET) yarns with an anti-static electricity and fire resistant coating. It is a kind of new type mine supporting mesh and a good substitute formetal mesh, plastic mesh, steel-plastic mesh and other traditional supporting material.

The wide range of Mining Grid goes from tensile strengths of 40kN/m to 1200kN/m. The standard roll sizeis 5m x 100m, but rolls can be supplied in other widths and lengths as customized.

Application:

  • Long-wall recovery systems
  • Mine roof/back support
  • Mine slope/high-wall protection
  • Anchoring and shotcreting tunnelsupporting
  • Substitute for metal/plastic mesh
  • Rockfall and building safetyprotection
  • Others underground civilengineering
