| Abstract: |
| The formation mechanism of high temperature sulfur zone was analyzed, and current thermometer and cooling measures were compared. Finally, saturated lime water was used to reduce temperature. Based on this analysis, nine high temperature sulfur holes of the 649 platform in the northern part of Dabaoshan were designed for deep hole blasting. Field practice indicated that the adverse effects of high temperature sulfur zone had been successfully eliminated. |
