Abstract: In view of the problem of lack of gas drainage concentration control and the high energy consumptionofthe waterringvacuum pump in the extensive control method of existing coal minegas drainage control, a coal mine gas drainage concentration control system was designed. The system is based on the h1erarch1cal adjustment1dea, and under the central zed control of the control program, the gas concentrat1on1ntheextract1onp1pelne1sdetectedbythegasconcentrat1onsensor,thegasconcentrat1on changerate1scalculatedbythePLClog1coperat1onfunct1on,andthentheopen1ngdegreeofelectr1cgas control valve and the variable frequency motor speed of water ring vacuum pump are adjusted by grade /ccording to the ch/nge of g/s concentr/tion to incre/se the concentr/tion ofg/sextr/cted,so /sto improveutiliz/tionr/teoftheextr/ctiong/s.Thetestresultsshowth/tthecontrolsystemc/nefectively increase the gas concentration of the extraction, and the gas concentration can be increased by 3.6% — 4.2%, which greatly improves the gas utilization rate of the extraction. And the energy saving effect is obvious, the energy saving e fect is improved by 24% after the gas drainage concentration control.
