Analog-simulation filling and compacting forming experiment method for mine coal-rock layers

Abstract

The invention discloses an analog-simulation filling and compacting forming experiment method for mine coal-rock layers. The method mainly comprises the following steps: selecting analog-simulation parameters according to site conditions; installing and adjusting an analog-simulation coal-rock layer filling and automatic sliding-type compacting device; uniformly mixing analog-simulation materialsof different coal-rock layers with water, filling, paving flat and forming; setting the sliding speed of a walking mechanism and the compacting force of a compacting rack; finely leveling the artificial paving surfaces of the analog-simulation materials by starting a walking motor to achieve uniform and homogeneous paving surfaces; performing automatic compaction with the uniform force on the fineleveled surfaces of the analog-simulation materials by startingacompacting motor, to complete the flat filling paving and compacting forming of a layer of analog-simulation materials; and lifting thecompacting rack upwards to the set position, distributing slits in the compacted analog-simulation materials, and performing stratification by spreading the appropriate amount of mica.

Description

technical field [0001] The invention relates to a method for filling and compacting similar materials for similar simulation experiments in mines, in particular to an experiment method for filling and compacting coal rock formations for similar simulation experiments in the fields of rock, soil, geology and mines, and belongs to the field of using experimental instruments and equipment. Background technique [0002] In similar simulation experiments, the process of layer-by-layer filling and compaction of similar materials is extremely time-consuming and laborious, and the existing process mainly relies on manual compaction. The usual method is to roughly smooth the loose material with a trowel after filling the material, and then manually use a flat iron block or steel plate to compact it. The level of the layer and the correct filling height mainly depend on visual observation. At the same time, most of the tamping machines currently used are manually supported and moved, ...
