摘要(Abstract)：

为确保在高温火区安全爆破的前提下,进一步增加高温火区爆破作业规模,稳步提升露天煤矿岩石剥离作业进度,结合宁夏大石头露天煤矿爆破现状,针对降温效果、孔内积水、炸药选择等进行深入研究。将PDCA循环安全管理与布孔钻孔、信息化测温、炮孔降温等进行有效结合,准确掌握了高温区分布情况,制定合理的降温方案;并针对裂隙区炮孔升温反弹等现象研究制作高温隔热护套,对炸药和起爆器材进行绝热保温,并在实践过程中使用反程序高温爆破,实现了高温火区安全高效爆破。实践证明,基于PDCA循环的高温爆破技术安全可靠,成本低,效率高,可在今后类似工程中推广应用。
In order to further increase the blasting scale in high-temperature fire areas under the premise of safe blasting in high-temperature fire areas and steadily improve rock stripping in open-pit coal mines under a promise of safety, this paper combined with the current blasting situation in Ningxia Dashitou open-pit coal mine, conducted a deep research on the cooling effect, the water accumulation in holes, and the choice of explosives. It combined the PDCA cycle safety management with hole design and drilling, information-based temperature measurement, and blasthole cooling, etc. The distribution of high-temperature areas is grasped accurately, and a reasonable cooling plan is formulated. For the phenomenon of blasthole heating and rebound in the fissure area, a high-temperature insulation sheath was made to insulate explosives and initiating equipment. During the operation, reverse program was used to achieve safe and efficient blasting in high-temperature fire areas. The practice has proved that the high-temperature blasting technology based on the PDCA cycle is safe and reliable, with low cost and high efficiency, and can be popularized and applied in similar programs in the future.
