摘要： A grout fillable prop has an inner member and an outer member adapted for movement between an extended use position and a retracted position. A grout inlet is formed in an upper part of a sidewall of the outer member to allow grout to pass into the prop. The inner member and the outer member have wall portions with plastic properties and are self-supporting. An installation fitting is fitted to the grout inlet and adapted to hold a grout filling tool without the use of separate fasteners. A one way valve is fitted to the installation fitting. The one way valve is formed of a length of lay flat hose one end of which is attached to the installation fitting. The hose locates inside the prop when the installation fitting is attached to the prop.

摘要： A single use grout fillable telescopic mine prop has self-supporting walls with plastic properties to withstand a much greater vertical displacement before failure. The prop has a unique installation fitting and a unique grout filling tool is provided to enable the prop to be quickly and safely filled. The prop is easy to maneuver into place by two workers as the design of the prop is lightweight. The prop has superior load withstanding properties and other properties to pumpable crib bags and grout filled steel props.
