  • Description:
    The objective of this research was to design, build, and demonstrate a support system to improve roof control in the entries of longwall mines. The objective of this phase was the detailed design of such a system and the selection of a test site in which to perform the pilot demonstration. The result is a complete set of detail drawings or specifications that define the three major components of the system. The gate support is a variation of a face chock that has an extended canopy and additional hydraulic legs to protect the region of the face-entry intersection. The entry support is a steel beam and hydraulic prop set that is reusable and serves to support the first 100 or more feet of entry inby the longwall face. The transporter is a bolter-like vehicle with a crane used for installing and retreating the beam sets. The completed drawings may be used to build a prototype system that can be tested in a remote section of a mine and then in the active longwall tail entry. [Description provided by NIOSH]
