Abstract

The invention discloses a fluid-solid coupled similar simulation experimental platform which comprises a box body top plate, a box body bottom plate, a front baffle, a rear baffle, a left lateral insertion plate and a right lateral insertion plate, wherein the box body bottom plate, the front baffle, the rear baffle, the left lateral insertion plate, the right lateral insertion plate and the box body top plate form a closed box body structure of the experimental platform; a transmission bar is arranged in the box body structure and is positioned above the box body bottom plate; a mining steel plate is arranged above the transmission bar and is movably connected with the transmission bar; a coal layer is laid on the mining steel plate; a simulated rock stratum is arranged above the coal layer; a data monitoring system is arranged in the simulated rock stratum; a pressure-bearing steel plate covers the top of the simulated rock stratum; and a hydraulic jack is arranged between the pressure-bearing steel plate and the box body top plate. The experimental platform disclosed by the invention is simple in structure and low in manufacturing cost, a research worker can directly observe and record the movement and deformation conditions of overlying rock and the water permeability condition in the rock stratum cracks under the mining action, and the influence of coal mining on permeability rules of surface water and karstic water is analyzed.

Description

technical field [0001] The invention relates to the field of underground mining, in particular to a fluid-solid coupling similar simulation experiment platform. Background technique [0002] The expansion of mining to the outside and deep has more and more serious impact on the water environment of the mining area, especially in the karst mining area, excessive drainage of groundwater, large-scale reduction of groundwater level, and environmental problems caused by shallow water leakage are more prominent , which not only seriously restricts the development and utilization of mineral resources and the sustainable development of the mining economy, but also brings huge hidden dangers to mining. Mining damage caused by underground coal mining is mainly manifested as ground subsidence, ground cracks, karst subsidence, shallow water leakage and water pollution, landslides and debris flows, etc. For southern karst mining areas, mining damage caused by coal mining is more serious,...
