| Abstract: | In the light of the special geological conditions of island working face,constantly test and improvement of coal injection technology were made from drilling,hole sealing method and water injection process.From the experimental data,it was found that the discharging modes which were used spiral drill pipe with compressed air,the sealing methods which were changed with the places,the water injection technique with low voltage small porous flow,can improve water flooding effect and meet the requirements of actual infusion. |
