Abstract

The invention discloses an intelligent permeability measurement test bench. The intelligent permeability measurement test bench comprises a data processing system, a water supply circulation system and a simulated percolation system. The data processing system comprises a plurality of pressure sensors, a plurality of low sensors, a pressure regulator, a data collection device and a computer; the water supply circulation system comprises a water feeding tank, a water feeding pump and a pressure control pump; the simulated percolation system comprises a percolation tank, an upper water tank, a lower water tank, a water stabilizing tank, a water collection tank and a similar material; a plurality of water diversion holes are distributed in each of a baffle between the upper water tank and thepercolation tank and a baffle between the percolation tank and the water stabilizing tank; a plurality of drainage pipes extending out of each of a baffle between the percolation tank and the water collection tank and a baffle between the percolation tank and the lower part water tank; and electric valves, the pressure sensors and the flow sensors are sequentially mounted on the drainage pipes. The intelligent permeability measurement test bench can measure the permeability of various rock samples to be measured at normal temperature and normal pressure, can rapidly and accurately measure thepermeability of rock samples with different fissure ratios, and is simple to operate, practical, and reliable to work.

Description

technical field [0001] The invention relates to a permeability measurement test device, in particular to an intelligent permeability measurement test bench. It can measure the permeability of strata with high fracture rate simulated by the collapse of overlying strata in coal mine goaf, and can also measure the permeability of sandstone or soil with different particle sizes, which is used in hydrogeology, engineering geology, environmental geology and other fields. Background technique [0002] During the mining process of the coal seam, the overlying strata in the goaf will collapse, and large-scale simulated cracks will cause a huge change in the permeability of the overlying strata in the goaf compared with the coal seam before mining. The current permeability measuring instrument It is mainly used to measure small rock samples with low permeability, and there are few intelligent devices for measuring the permeability of the overlying strata in the goaf after the subsiden...
