  • Publication number: 20240076985
    Abstract: For the problem of difficult roof anchor withdrawal at the end of a working face, a static crushing directional anchor withdrawal method at the end of a large-mining-height working face is provided. The method includes the following steps: designing key parameters of boreholes for static crushing, including a borehole position, a spacing between boreholes, a borehole depth, and a borehole diameter at the end of a working face; then determining parameters of a static crushing agent grouting technology device for the construction of a static crushing process; and carrying out an anchor withdrawal operation at the end.

  • Patent number: 9414905
    Abstract: A muscle prosthesis with a suspension fixing apparatus for implantation into a human body and production method thereof; the muscle prosthesis comprises a muscle prosthesis main body and the suspension fixing apparatus; the suspension fixing apparatus consists of at least one stretchable part and at least two fasteners; the suspension fixing apparatus can fix the muscle prosthesis to a human bone or human muscle tendon and fascia. The suspension fixing system can change the thickness and outer shape of the prosthesis according to the direction and intensity of a tensile force, thus satisfying the requirements of different body parts and different muscle thicknesses. Use of the suspension fixing apparatus allows the prosthesis to be fixed firmly and be structurally stable, thus solving the technical problem of drooping and shifting prostheses.
