仅管目前已经在广泛地研究利用热力破碎,水电效应。高频率,及冲击回转等新的钻进方法来破碎坚硬岩石,但从已获得的技术进展来看,它们距离以工业规模在生产上采用的阶段尚远,因而钻进坚硬岩层,依然以金刚石钻进及钻粒钻进为主,金刚石钻进,它可以在钻井内以很高地转速进行工作,並且可以在任何方向上进行钻进,在钻速上比现有的硬合金与钻粒钻进都高,可以无显著磨钝地钻完数十公尺到数百公尺,因而在拥有金刚石产地的国家
Despite the current extensive use of thermal crushing, hydropower effects. High frequency, and impact rotation to break hard rock, but from the technological advances that have been obtained, they are still far from being manufactured on an industrial scale, so drilling into hard rock is still based on diamond Drilling and drilling The main diamond drilling, drilling, it can work in the drilling at very high speeds, and can be drilled in any direction, the drilling speed than the existing hard alloy and drill bit Into the capital are high, you can drill without significant blunt to dozens of meters to hundreds of meters, which has a diamond origin in the country
