摘要： A system or method for a structural mine roof support includes a roof support apparatus that includes a cylindrical cladding defining a hollow interior, a plurality of bamboo sections disposed in the hollow interior and coaxial with an axis of the cylinder. Also, a roof support apparatus with a cylindrical cladding defining a hollow interior, a plurality of bamboo sections disposed in the hollow interior and coaxial with an axis of the cylinder, and voids between adjacent bamboo sections, the voids being injected with a filler material, e.g., polyurethane foam, to maintain axial positioning of the bamboo sections when under load. The support apparatus configured to load and to yield in a predetermined fashion to control a mine roof from sudden failure.

摘要： A mine roof support comprises two or more frusto-conical, tubular sections, the sections each flared outwardly from an upper end to a lower end thereof, a skirt portion of a section being received and secured within a neck portion of a section below in a frictional fit to define an interior volume of the mine roof support. A solid, compressible, load-bearing material is located within the volume. Methods of installing a mine roof support and a pre-installation assembly for a mine roof support are also disclosed.

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 grout pack [1] restraining envelope is provided which includes a plurality of restraining rings [7, 8] shaped to extend circumferentially around a grout bag [2] in a vertically spaced arrangement up at least a part of the height of the grout bag to provide support against lateral deformation of an installed grout pack as it occurs under axial load. At least some of the restraining rings are of differing tensile strengths or are configured to yield at differing tensions. The grout pack may have a collapsible polymer or wire mesh [3] positioned on the inside of the restraining rings to which at least some of the restraining rings are fastened. Restraining rings [7] of relatively higher tensile strength are provided at vertical positions at which relatively greater lateral deformation of the grout bag is expected, and rings [8] of relatively lower tensile strength are provided at vertical positions at which relatively less lateral deformation of the grout bag is expected. The restraining rings may be of the yielding or non-yielding type.

摘要： A method of producing structural supports for use particularly in mining applications includes the use of a relatively rigid and cylindrical shell casing. The shell casing is separable along the plane parallel to its axis, has open ends and is closed about a fabric tube which is axially supported therein. The fabric tube is filled with pressurized liquid building materials such as concrete. Once filled within the casing, the pressure of the building material forces the liquid component thereof out of the tube laterally and through perforations provided in the shell casing to drain the liquid away from the building material in the tube. The casing and tube are of size such that the remaining building material, which will constitute a pillar, extends completely between the surfaces it is to separate and support. Once the liquid has been drained from the building material within the fabric tube and shell casing, the shell casing can be removed even before the remaining building material is hardened into a pillar reinforced with an outer fabric tube. The shell casing can then be reused for producing additional fabric reinforced pillars.
摘要翻译： 生产用于特别是在采矿应用中的结构支撑件的方法包括使用相对刚性和圆柱形的外壳。 外壳可沿平行于其轴线的平面分离，具有开口端，围绕轴向支撑在其中的织物管封闭。 织物管充满加压液体建筑材料如混凝土。 一旦填充在壳体内，建筑材料的压力就将液体组分横向挤出管子，并通过设置在壳体壳体中的穿孔将液体排出管中的建筑材料。 外壳和管的尺寸使得构成柱的剩余建筑材料在其要分离和支撑的表面之间完全延伸。 一旦液体已经从织物管和壳体壳体内的建筑材料排出，即使在剩余的建筑材料被硬化成由外部织物管增强的柱子之前，壳体也可以被去除。 然后可以将外壳重新用于生产额外的织物加固柱。

摘要： Connected support sections for a mineral face conveyor are individually supported on the forward sides of chocks which move in towards the rib of a panel behind a mining machine. Backfill is transported to the mined area behind the moved-up chocks via a conveyor supported from connected support sections on the rear sides of the chocks.
