摘　　要：热熔钻进是一种新式钻进技术。自从 2 0世纪 6 0年代 ,美国LosAlamosNationalLaboratory (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。The subterrene drilling method is a new excavation technology Since the 60′s of 20 centuries when the United States started studying drilling exploring,the structure design and material choice of subterrene has not been determined unanimously Studies of our country in this respect are late Based on the results of experimental study,the author take thesubterrene with 80mm diameters as an example to proceed the improvement design on its inner heating resistor structure
