美国洛斯阿拉莫斯国立实验所的地球物理学家研制成一种可熔化岩石的新型热钻头。这钻头的长度为7.5厘米,将它装在4米长的钻杆头套上,能以1200℃的高温在玄武岩中熔化出深度达27米左右的孔。
Geophysicists at the Los Alamos National Laboratory in the United States have developed a new hot drill bit that melts rocks. The drill, which measures 7.5 cm in length, is mounted on a 4-meter long drill-head cap and can melt holes deep in basalt to a depth of about 27 meters at a high temperature of 1200 ° C.
