在人类乘航天飞机在广阔无垠的宇宙中遨游的今天,人类在地层深处的活动也日益活跃。横贯江河的水下隧道,穿越闹市的城市地铁,为灌溉和发电用的地下引水隧洞,崇山峻岭中的铁路公路隧道,以及深入采区的煤矿和各种采矿巷道都需要人类加快挖掘,而传统的凿岩爆破法掘进已明显不能适应快速掘进的需要。为此,科技发达国家都在研究新的破岩方法和掘进技术,自50年代起,相继发明创造了用 Today, as humans fly by the space shuttle in the vast universe, humans are also increasingly active in the depths of the earth. Underwater tunnels crossing the river, crossing downtown metro, underground diversion tunnels for irrigation and power generation, railway tunnels in high mountains, and coal mines and various mining tunnels in deep mining areas require humankind to expedite the excavation. The traditional Drilling blasting method has obviously can not adapt to the needs of rapid excavation. To this end, science and technology developed countries are studying new methods of rock breaking and tunneling technology, since the 1950s, have invented the use of
