Abstract:Jiahe Coal Mine adopts the technology of drawing out gas based on coal order to prevent coal and gas outburst , but the bedding drilling efficiency seriously affects digging efficiency of combine mechanized heading .In order to improve the bedding drilling efficiency , Jiahe Coal Mine has introduced the CMS 1-6200/80 drilling car and done the bedding drilling drainage exper-iments.Through analyzing the existing problems of the drilling construction technology , Jiahe Coal Mine propose solutions such as through improving drill pipe , optimizing drill speed , increasing the pressure of pressure pump , projection depth correction for 80m, correcting the parameter of measures drilling projection depth for 80m.Then the drilling efficiency improve effectively and the drilling rate of progress raise 17%.The using of the CMS1-6200/80 type drill carriage in Jiahe Coal Mine provides refer-ence for large-scale promotion in Xuzhou Mining Group.
