Problems solved by technology

[0004] In order to solve the technical problems existing in the prior art, the lack of tamping thrust in the gangue filling simulation experiment, uneven pushing and pounding of the filling material, insufficient density of the filling material, and crude experimental equipment lead to irregular operation, inability to simulate and truly reflect the on-site engineering Problems such as large deviations between actual, laboratory and field results

Embodiment Construction

[0012] like figure 1 Shown is a schematic structural diagram of a portable filling mining tamping simulation device used in a filling mining tamping simulation method of the present invention. The filling mining tamping simulation method is completed by a portable filling mining tamping simulation device. The simulation device mainly It is composed of box body 1, rotating handle 2, rotating threaded rod 3, separate hydraulic jack, oil hose 4, spherical hinge joint 5, hinge joint support 6, and lateral limit plate 7; box body 1 has a thickness of 1cm The steel plate is welded, and the top cover is fixedly connected with bolts, which is convenient for dismounting the top cover, so that it is convenient to maintain and repair the objects inside the box body 1. Easy to disassemble In order to make the box body 1 provide enough support without deformation, the back plate of the box body 1 is welded with a thick 2cm steel plate, and the entire box body 1 outer surface is sprayed wit...

Abstract

The invention relates to a tamping simulated method of filling mining, and belongs to the technical field of gangue filling mining. Construction principles and experimental effects of the tamping simulated method satisfy requirement for a compacting mechanism lab simulated experiment of a spoil filling support. The whole operation process of the device is highly similar with that of practical filling compacting process, material compacting rules of the practical filling compacting process can be mastered by simulation experiments in a lab, labor, material and financial resources as well as time cost of industrial test can be reduced, uncertainty of an industrial test result is reduced, and the economic effect is high. A device is portable, related parameters can be changed, and requirements of different occasions can be met.

Description

technical field [0001] The invention belongs to the technical field of coal gangue filling and mining, and in particular relates to a compacting simulation method for filling and mining. Background technique [0002] In the coal gangue filling and mining process, the filling support is an indispensable equipment, which plays an important role in the transportation, filling and compaction of coal gangue. The tamping mechanism of the gangue filling support is responsible for the filling and compacting of coal gangue in the goaf, which is a distinctive feature different from other supports. After the gangue is filled into the goaf, the compacting mechanism pushes and tamps it, increases the density of the loose gangue on the basis of pushing and tamping, improves the compression resistance of the filled gangue, and makes it able to withstand certain roof subsidence The pressure can reduce the sinking of the roof, thereby effectively controlling the subsidence of the ground sur...
