摘要
热熔钻进是一种新式钻进技术。自从20世纪60年代,美国Los A lamos国家实验室(LANL)开始研究热熔器钻具以来,对热熔器的结构及材料的选择一直没有完全定位。我国在这方面的研究进行的比较晚,在试验结果研究的基础之上以直径80mm热熔器为例对其内部加热电阻进行了改进设计。
The subterrene drilling method is a new excavation technology. Since the 60s in 20thcentury when the Los Alamos National Laboratory started studying drilling exploration, the structure design and material choice of subterrene has not been fixed perfectly. Studies in this field in China started late, and the author did some improvement on the inner heating resistance structure taking an 80ram diameters as an example.
