In order to solve the problems of unreasonable negative pressure distribution in gas drainage drilling holes,fast attenuation speed of coal seam gas drainage concentration and so on in Liuzhuang Coal Mine,and further improve the effect of coal seam gas drainage,a coal seam gas drainage drilling holes regulation and control model is constructed based on support vector machine regression machine technology.The judgement and identification and strategies of coal seam gas drainage drilling holes regulation and control are proposed,and an intelligent regulation and control system for coal seam gas drainage drilling holes is developed,the on-site engineering application is carried out in the 151108 working face of Liuzhuang Coal Mine.The results show that the coal seam gas drainage drilling holes regulation and control model can effectively determine the optimal drainage negative pressure for gas drilling holes;when using the intelligent regulation and control technology of coal seam gas drainage drilling holes for group holes regulation and control,the concentration of coal seam gas drainage can be increased by more than 15%,while when using single hole regulation and control,the concentration can be increased by more than 30%,which can effectively extend the effective drainage period of drilling holes gas and improve the coal seam gas drainage capacity.
