A grouting system for anchoring a reinforcement in a mine includes a package that is a tubular member formed of polymer film and has discrete first and second compartments. Hardenable cementitious material that is a hydratable substance and water is disposed in the first compartment. A method of forming a resin grouting capsule includes: injecting a hardenable material into a first compartment of the capsule having resin mastic; wherein the hardenable material does not substantially react with the resin mastic when injected into the first compartment. Another method of forming a resin grouting capsule includes: injecting a hardenable material into a first compartment of the capsule having catalyst mastic; wherein the hardenable material does not substantially react with the catalyst mastic when injected into the first compartment.

Anchoring systems for mines

A method is disclosed for packaging a curable resin composition and a catalyst composition that react with each other when mixed, comprising providing a partitioned tube for receiving the resin composition and the curing agent in separate compartments; delivering a stream of a resin composition into one compartment of the tube; delivering a stream of a curing agent in the other compartment of the tube; advancing the partitioned tube and constricting and sealing the partitioned tube at spaced apart intervals and severing the sealed tube to produce a package partitioning the resin composition from the catalyst composition. Solid particulate is continuously added into the stream of at least one of the catalyst composition and the resin composition and mixing the solid particulate and stream to produce a mixed composition; and the relative amount of solid particulate in the mixed composition is controlled by continuously determining the mass of solid particulate added to the mass of the stream.

Resin cartridge production system

A method of forming a partitioned package for grouting for an anchoring system for a mine includes pumping a mastic into the package through a fill tube while a processing lubricant is separately introduced onto an inner wall of the fill tube.

Filling of partitioned film packages for anchoring systems for mines

A mine support includes an elongate metal member and a coating comprising post-consumer recycled thermoplastic disposed on the member. The thermoplastic may include post-consumer recycled poly(ethylene terephthalate), and the coating may be an injection molded coating. A first layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 16% and about 30%, and a second layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 6% and about 14%. Either the first layer or second layer may contact the elongate metal member.

Coated mining bolt

Provided is a system and method for producing resin cartridges that can be used in mine roof bolt applications. The system and method can be used to produce resin cartridges that contain a first portion that includes a resin and a catalyst that cure at a first speed when mixed together and a second portion that includes a resin and a catalyst that cure at a second speed when mixed together. The system can include a base material supply source, a plurality of branch lines, at least one altering material supply line in fluid communication with at least one branch line, a valve arrangement, a product line, and a packaging machine.

Multi-speed resin cartridge production system

System and method for producing resin cartridges

A partitioned package includes an inner tube having a longitudinally extending seal and containing a first material, and an outer tube having a longitudinally extending seal and surrounding the inner tube and containing a second material. The seals of the inner and outer tubes are positioned at different radial locations.

Partitioned film package

A method of adjusting gel time of a grouting system used for anchoring a reinforcement in a mine includes adding inhibitor to initiator of the grouting system, the inhibitor and initiator being disposed together in a first compartment of a multi-compartment shreddable package.

Anchoring systems and methods of use thereof

A nut having an injection-molded insert or delay stopper is threaded onto an end of an anchor. A capsule containing a resin component and a catalyst component and the other end of the anchor are positioned in a bore hole in a mine roof, mine wall, side of a hill, concrete wall, or concrete floor. The threaded end of the nut contacts the insert and rotation of the nut rotates the anchor, breaking the capsule and mixing the components. After the components set, increased torque is applied to fracture the insert and move the nut up the threaded end of the shaft against roof stabilizing components on the shaft.

Torque nut having an injection molded breakaway insert

A process for producing partitioned packages by which a first film is formed into an elongated inner tube and a second film is formed into an elongated outer tube surrounding the inner tube. Reactive components are filled into the inner and outer tubes as the tubes are formed to maintain the reactive components separate from each other. Only the outer tube is actively engaged to advance the tube longitudinally. Frictional forces from the advancing outer tube are applied to the component within the outer tube and, in turn, are applied to the inner tube thereby advancing the inner tube at a rate substantially the same as the outer tube.

Device for forming partitioned film packages

A resin bonded mine roof bolt having an elongated rod with a first end, a second end, and a resin control surface positioned on the rod between the rod first and second ends. The resin control surface has a channel extending along the length of the bolt for distributing resin and interrupted spiral threads for mixing resin. When installed in a mine roof bore hole with curable resin, the resin control surface mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt.

This invention relates to a process for converting silica to polysilicate gels or hydrogels by combining an aqueous silica source with a COfeed stream as the gel initiator, whereby the reaction stream is propelled at high velocity and turbulence maintaining the COuptake rate in the reaction stream. The invention also relates to a process for converting silica to polysilicate by pre-carbonating water at pressures of equal to or greater than 100 psig before initiating the polysilicate reaction.

High velocity, low pressure process for making silica gels and microgels

A composite material is disclosed having a matrix formed of polyethylene terephthalate and cement particles distributed in the matrix. The cement particles may be Portland cement. About 50 wt % or less of the composite material is cement particles. The cement particles have an average particle size of no more than about 100 &#x3bc;m.
