摘要： A polymer mesh for skin control in hard rock mining conditions is provided. The polymer mesh is manufactured using a knitted or woven design that further includes one or more pairs of solid cut-resistant bands. The bands are positioned in pairs, each band in a pair having a width of at least about 2.5″ and being generally parallel with the other band. The bands are spaced from one another at a distance of between about 1.5″ and about 4″ to create a reinforced aperture between the bands. One or more reinforcement bolts are installed within the aperture with the bands on opposing sides of each bolt buffering the edges of the steel plates associated with the bolts to prevent the plates from tearing the polymer mesh.

摘要： A method of treating tunnel collapse includes leveling a collapse body and moving a pavilion support under the collapse cavity, lifting a shield plate until a lower edge of the shield plate surpasses a contour line of an initial supporting arch of a tunnel, connecting a bottom column and inserting a padding plate under a column. If the hydraulic prop retracts, the column, the bottom column, the padding plate and the hydraulic prop bear a load from the shield plate. Mounting and connecting the initial supporting arch, welding the intersection point of the column and the initial supporting arch, cutting off the column in the initial supporting arch. Transferring the load of the shield plate from the pavilion support to an initial supporting shed, spraying fast-setting concrete to a grid arch to form a closed shell, and pumping filling material to fill the space of the collapse cavity.

摘要： A mesh handler for a mining machine includes a generally U-shaped frame arranged for receiving and positioning at least one mesh against a roof portion of an underground tunnel. The frame includes at least one generally U-shaped rail and a guide mechanism arranged for guiding the mesh along the rail in a direction substantially perpendicular to a longitudinal direction of the mining machine. Moreover, a mining machine including the mesh handler is provided.

摘要： An asymmetric support structure of entry driven along, gob-side (EDG) under unstable roof in deep mines and construction method thereof. The asymmetric support structure includes roadway roof support structure, a gob-side support structure and a solid coal seam-side support structure. The roadway roof support structure includes a reinforcing wire mesh, a W-section steel strap, high-strength pretensioned bolts, and cable bolts and matching steel straps. The gob-side support structure includes a reinforcing wire mesh, a W-section steel strap, high-strength pretensioned yielding bolts and grouting cable bolts and its matching steel straps. The solid coal seam-side support structure includes a reinforcing wire mesh, a reinforced beam and steel strap pallet subassembly, high-strength pretensioned yielding bolts and cable bolts and its matching steel straps. The roadway roof support structure, gob-side support structure and solid coal seam-side support structure beneficially together form the asymmetric support structure.

摘要： The invention provides a machine for tunnelling in rock. The machine includes a pilot drill assembly for drilling a series of interfering parallel holes or a pilot hole into and generally perpendicular into a rock face and a blast hole drill assembly for drilling a series of blasting holes around the pilot hole or previous blast hole. The machine further includes a charge handling and loading assembly for loading the first series of holes with propellant charges and an ignitor system for igniting the charges. Included further is a rock clearing means for removing the blast rock from the blast face and a rock pick for clearing and picking the floor, roof or walls to provide access for the machine into the tunnel and a mobility assembly for moving the machine forward. Also included is a control console provided with control means for controlling the pilot drill assembly, blast hole drill assembly, charge handling and loading assembly, ignitor system, rock clearing means, the rock pick, a measure system for gas detection and management, a rock stress measure system and recording system.
