Abstract: The present invention provides for a compressible grout mix for filling an annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation and a method of filling the annular gap between a tunnel rock wall surface and a tunnel liner of a tunnel in a rock formation subject to time dependent deformation after excavation utilizing the compressible grout mix for resilient absorption of forces in the hardened state of the compressible grout mix exerted by the time dependent deformation of the rock wall surface into the tunnel opening. The method includes: a. providing the compressible grout mix comprising hydraulic binding agent, bentonite clay, polymer foam particles, water-reducing admixture, water and air, b. placing the compressible grout mix in the annular gap between the tunnel wall rock surface and the tunnel liner, and c. allowing the compressible grout mix to set, wherein the compressible grout mix in the hardened state has a compressible ratio greater than the anticipated time dependent deformation.

Abstract: The present application relates to a system for supporting a roof of a portion of a mine. The system includes a first plurality of stabilizing members disposed above the roof at a first elevation. The first plurality of stabilizing members originate from a first common location and terminate at a second elevation that is higher than the first elevation. The system further includes a second plurality of stabilizing members disposed above the roof and the first plurality of stabilizing members at a third elevation. The second plurality of stabilizing members originate from a second common location and terminate at a fourth elevation that is higher than the third elevation. The second plurality of stabilizing members are disposed generally perpendicular to the first plurality of stabilizing members.

Abstract: A fractured roof 110 mining method entry-side anti-collapsed structure, one working face of the 110 mining method corresponds to one roadway but without retaining any coal pillar, the roadway retains an entry after the previous working face implements mining top-cutting pressure release, and a roof of the roadway is arch-shape, directional cutting is conducted on one side of the roadway, and the cutting angle is between 15-20 degrees. One working face corresponds to one roadway but without retaining any coal pillar when underground mining is conducted, which can save resources and improve recovery rate of mining. And, the roof of the roadway of the retained entry is arch-shaped, which can improve safety and ensure safety of the coal mining working face. In addition, a cutting angle is 15-20 degrees, which can effectively determine a roof caving direction after top-cutting and reduce affect to the retained entry.

Abstract: The water-insoluble filler in the form of bubbles is provided into the underground cavern. Then, the filler thus provided is allowed to adhere to a bottom surface and a lower wall surface of the underground cavern to permeate thereinto. Subsequently, the filler having permeated is cured. Here, the water-insoluble filler in the form of bubbles may be provided again into the underground cavern. Moreover, water is poured into the underground cavern to float up the filler. The filler having floated up is allowed to adhere to an upper wall surface and a ceiling surface of the underground cavern to permeate thereinto. Thereafter, the filler having permeated is cured. Here, when the filler is allowed to permeate an inner surface of the underground cavern, a pressure inside the underground cavern may be increased. Additionally, when the filler is cured, a temperature inside the underground cavern may be increased.

Abstract: A gas containment system can include a gas barrier layer forming a capsule. The gas barrier layer can be made up of a particulate swelling clay, a non-swelling particulate material mixed with the particulate swelling clay, water, and a water-soluble polyol. The water can hydrate the particulate swelling clay and form a continuous liquid phase in the gas barrier layer. The water-soluble polyol can be dissolved in the water. The gas containment system can further include a gas retained inside the capsule.
