The present invention is a continuous and multi-layer pre-supporting method with downward short anchor cables. Starting from the second layer, the following pre-supporting operation is carried out after the one-step mining and slitting is completed: first, along the one-step mining and slitting, the upper position of the two sides of the bottom plate is Excavate a downwardly inclined drilling hole, then install the supporting threaded steel in the borehole and pour cement slurry, and then use the same rooting threaded steel to connect the tails of the supporting threaded steel in the same one-step mining section together, and then Carry out stope cement filling operations. After the two-step mining operation is completed, the tailings are filled. The method implements advanced, continuous and multi-layer support for the mining body, and can completely cure the roof caving of the stope.

The invention discloses a preparing method of a braided tube homogeneously-enhanced type polyvinylidene fluoride hollow fiber film, and belongs to the field of polymer film product preparation. The preparing method includes firstly preparing a polyvinylidene fluoride solution A having a certain low concentration, dipping a braided tube with the solution A to allow the polyvinylidene fluoride solution to penetrate into the inside of the braided tube, coating the outside of the braided tube with a high-concentration polyvinylidene fluoride film casting solution B having a certain formula, and putting the braided tube coated with the solution A and the solution B into a coagulating bath to allow the polyvinylidene fluoride coated in the two times to be subjected to phase separation simultaneously. The polyvinylidene fluoride hollow fiber film prepared by the method is advantageous in that 1) the inner low-concentration polyvinylidene fluoride solution tightly surrounds fibers of the braided tube, is tightly connected to an outer film layer after phase transition, and is not liable to shed; 2) a high-aperture-ratio compact surface layer is formed from the outer high-concentration film casting solution and provides effects of filtration; and 3) the braided tube with high strength provides excellent film fiber longitudinal stretching strength.

The invention relates to a rolled plate hoisting gasket, belonging to the technical field of hoisting tools. The gasket comprises a length of arc-shaped bending plate mainly identical to an inner ring of the rolled plate, the bending plate is provided with a vertical baffle along an arc side thereof, an external arc surface of the bending plate and an inner surface of the vertical baffle are respectively provided with ferromagnets at intervals, and an inner arc surface of the bending plate is provided with a bump. In comparison with the existing rolled plate gasket, the gasket provided by theinvention has the following advantages that: 1) with the ferromagnets, the gasket can be closely attached to the inner ring of the rolled plate just by only a small length of the arc-shaped bending plate, and the gasket not only has small volume, low cost and convenient use, but also cannot fall off in the process of use; 2) the vertical baffle can further prevent a nylon hoisting belt from contacting an external end surface of the rolled plate, so that the external end surface of the rolled plate is protected; 3) with the bump, an extrusion force applied on the whole gasket by the hoisting belt can be transferred from a corner of the vertical plate to the bump, so that the extrusion force applied on the inner ring of the cold-rolled plate by the hoisting belt is further reduced, and abrasion of the bending plate and the corner of the vertical plate is avoided.

The invention discloses a ceramic and silver inlaying combination process. The process comprises the following steps: (1) a ceramic cup with an upper port smaller than a blank body is selected; (2) silver is smelted; (3) a cast plate is rolled as a sheet; and the molten silver is cast as a plate; (4) molding and stretching: the silver plate is hardened in the process of repeatedly rolling as a silver coil; the silver coil is heated to 200 DEG C for softening; and a silver sheet part is repeatedly punched and stretched by multiple times to form a cylindrical silver liner matched with the inner diameter of ceramic; and (5) silver and ceramic are combined in an inlaying manner. The ceramic and silver inlaying combination process breaks through a conventional method of bonding silver with ceramic by glue, so that prepared silver and ceramic are more healthy and environment-friendly in use without falling forever, and are longer in life; and in addition, silica gel with a hardness of 55A is selected, and the pressure tonnage in extrusion of the silver liner and the ceramic cup is strictly controlled, so that the damage rate caused by ceramic breakage and burning deformation can be effectively reduced.
