Abstract: A ventilation method for a high gas working face based on alternating intake and air return in a mine gallery is provided. In this method, an isolated island working face is divided into several sections along a strike direction. A coal pillar is alternately set as a conventional section and a gas-drainage section. Opposite coal pillars in the two mine galleries within the same section are respectively used as the conventional section and the gas-drainage section. Two mine galleries on both sides of the isolated island working face are alternately used as an intake gallery and a return gallery. The coal pillar at the side of the mine gallery as the return gallery is the gas-drainage section. A gas-drainage hole communicating a goaf is provided in the gas-drainage section, so that gas in the goafs at two sides of the isolated island working face can be extracted alternately.

Abstract: Disclosed is a method for backfilling and reconstructing a carbon storage space in an abandoned main roadway and storing CO2. A surrounding rock of the main roadway is surveyed through geophysical exploration technology, and an anchor bolts (anchor cables) are used to reinforce and support an area which has unstable confining pressure bearing. According to a width and a height of the roadway section of the main roadway, a support formwork is forged in advance, and after the support formwork is placed in the main roadway, backfilling slurry is injected to the periphery of the support formwork. Meanwhile, supercritical carbon dioxide is injected into the backfilling slurry and the roadway, respectively.

Abstract: Disclosed is a corrugated-flat rolling composite method for a steel/aluminum/aluminum alloy laminated composite plate. According to the method, a steel/aluminum laminated composite plate with a good plate shape and a firmly bonded interface is prepared, the corrugated cold rolling with a large thickness ratio is utilized to enhance the deformation of the interface to be bonded, and the deformation of constituent metals is coordinated to solve the problem that the steel-aluminum interface is not deformed. Then the deformation of constituents is coordinated by the interfacial corrugated-flat hot rolling to achieve the bonding of aluminum and aluminum alloy surfaces and prepare a high-performance steel/aluminum/aluminum alloy laminated composite plate. Taking the advantage that the interface oxidation has little effect on the bonding of aluminum and aluminum alloy, the problem of anti-oxidation in the composite process is eliminated, thereby the problem of low interfacial bonding strength is solved due to a fact that the interfacial shear becomes weak and the interfacial bonding mainly depends on the hot-press action when the steel and aluminum bonding surface approaches the neutral layer in the rolling process of a steel/aluminum/aluminum alloy laminated composite plate with a thickness more than 4 mm, and the problem of uncoordinated deformation is solved due to the large difference in the properties of steel, aluminum and aluminum alloy.
