Abstract: Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.

Abstract: Disclosed is a method for measuring gas pressure of a close-distance seam group simultaneously, including the following steps: constructing a pressure-measuring drill hole inclined downwards; lowering a first seam piezometer tube, lowering a baffle and a polyurethane blocking material after a tube head reaching a lowermost seam; and installing a gas pressure gauge; lowering a second seam piezometer tube, lowering the baffle and the polyurethane blocking material after the tube head reaching a second layer of seam; and installing the gas pressure gauge; lowering a nth seam piezometer tube, lowering the baffle and the polyurethane blocking material after the tube head reaching a nth layer of seam; and installing the gas pressure gauge; injecting a high-water and quick-solidifying material into the drill hole; and connecting the gas pressure gauges through optical fibers, and connecting the gas pressure gauges with a ground control system.

Abstract: Disclosed are a hydro-mechanical coupling experimental device with CT real-time scanning and a use method thereof. The hydro-mechanical coupling experimental device with the CT real-time scanning includes a CT scanning room and further includes a support frame, a hydro-mechanical coupling mechanism and a jack that are arranged in the CT scanning room. The support frame includes a base, a top plate, a plurality of columns for arranging the top plate and the base at intervals, and a movable plate that is arranged between the top plate and the base and can slide on the plurality of columns. The hydro-mechanical coupling mechanism includes an experimental box, a pressure box arranged inside the experimental box and a compression leg slidingly worn on a top of the experimental box; and the experimental box is arranged on the movable plate, and the jack is arranged on the base.
