Abstract

The invention discloses a multimedium permeability experimental device, which comprises a specimen tube, a gravel sample layer, a concrete sample layer with fractures, and a broken stone sample layer, wherein the gravel sample layer, the concrete sample layer and the broken stone sample layer are arranged in the specimen tube from top to bottom in sequence; the bottom of the broken stone sample layer is provided with a filter plate; a sand water containing plastic bucket is arranged below the filter plate; the top of the gravel sample layer is provided with a sealing element; the bottom, the middle part and the top of the gravel sample layer are respectively connected with a N0.1 piezometer tube, a No.2 piezometer tube and a No.3 piezometer tube; the other ends of the N0.1 piezometer tube, the No.2 piezometer tube and the No.3 piezometer tube are all clung and connected with coordinate paper; the top of the gravel sample layer is connected with a water tank through a conduit; a thin iron wire penetrates through the fracture area of the concreate sample layer with the fractures; the bottom end surface and the top end surface of the fracture area are provided with thin plastic skins; the top end of the thin iron wire is connected with the bottom end of the thin plastic skin to penetrate through the center of the filter plate to be twisted into one strand of iron wire.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to a multi-media penetration test device and a test method thereof. Background technique [0002] Coal mines are mined under porous aquifers, and the biggest threat of water damage is that the water (sand) in the porous aquifers breaks into the goaf through the water-conducting fracture zone, causing disasters and accidents. In the 1022 fully mechanized mining face of Taoyuan Coal Mine in Huaibei Coalfield, Anhui Province, a water inrush and sand inrush accident occurred in the pore aquifer, resulting in 5 deaths and tens of millions of direct economic losses; 2 In the 22 working face, there was an accident of water inrush and flooding of the porous aquifer, and the loss was hundreds of millions of yuan. [0003] Coal seam mining usually has "three zones" in the roof overlying rock: from bottom to top, there are caving zone, water-conducting fissure zone and bending zone...
