The absorption tower I and the absorption tower II are respectively provided with finished gas outlets and switching ports, and a gas inlet of the raw gas compressor is located at the upper corner of a mining zone. A gas outlet of the raw gas compressor is communicated with the switching port of the absorption tower I by a raw gas valve I, and is communicated with the switching port of the absorption tower II by a raw gas valve II. A suction inlet of the resolution vacuum pump is communicated with the switching port of the absorption tower I by a resolution gas valve I, and is communicated with the switching port of the absorption tower II by a resolution gas valve II. The PSA separation device can separate methane gas in the low-concentration gas, air can cycle to the upper corner of the mining zone, and the gas can be recycled after being discharged as energy gas. The PSA separation device not only solves the safety problem of the mining work surface, but also makes use of coal bed gas.
