高温硫化区深孔爆破技术分析

Deep-hole blasting technology analysis in high temperature sulfur zone

分析了高温硫化区的形成机理,并对目前的测温仪及降温措施进行了对比,最终采用饱和石灰水降低孔内温度。在此基础上,对大宝山北部649平台的9个高温硫化孔进行了针对性的深孔爆破设计。现场实践表明,成功消除了高温硫化区的不利影响。

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.
