Abstract

The invention provides a visual simulation test system for gas-liquid two-phase countercurrent in an abandoned mine goaf, and belongs to the technical field of abandoned mine goaf simulation test systems. The visual simulation test system comprises a simulation device for simulating a fracture network of the abandoned mine goaf, a gas supply system and an automatic water pressure controlling system, wherein the simulation device comprises a transparent observation box and a rock material arranged in the observation box; the gas supply system comprises a gas supply pipe and a gas cylinder for supplying gas to the gas supply pipe; the automatic water pressure controlling system comprises a pressure stabilizing tank, a pressure sensor, a pressure regulating gas cylinder, a water supply tank,a pressure test water pump, a water supply pipe and an electronic controller. The system can be used to simulate the gas-liquid two-phase countercurrent in the fracture network of the abandoned mine goaf, and realize the test of countercurrent visualization to reveal evolution of accumulated water and enrichment of gas in a closed-pit mine during long-term abandonment.

Description

technical field [0001] The invention relates to the technical field of a goaf simulation test system in an abandoned mine, in particular to a gas-liquid two-phase counterflow visualization simulation test system in the goaf of an abandoned mine. Background technique [0002] With the continuous increase of the mining intensity of coal resources in our country, more and more mines will be mined and completed as abandoned mines. It is estimated that the number of abandoned mines in my country will reach 12,000 in 2020 and 15,000 in 2030, of which There are abundant resources in the goaf of abandoned mines. It is preliminarily estimated that the coal resources in them are as high as 42 billion tons, and the coalbed methane resources are nearly 500 billion m³. my country has a large number of abandoned mines, rich resources, huge development potential, and good development and utilization. This part of coalbed methane resources can not only make up for the shortage of natural gas ...
