国外正在研究的新型钻岩方法有20多种,如火箭钻、爆炸钻、侵蚀钻、电弧钻、等离子体、涡轮、高频、核钻、激光、电子束、微波、弹丸、感应、超声波钻岩等。按钻岩的机理分为利用机械应力钻岩、热剥落和熔融气化、以及利用化学反应钻岩等。上述新钻岩法,多数还处于实验阶段,目前最有成效的还是机械钻岩法,如金刚石钻等。 There are more than 20 new types of rock drilling methods under study abroad, such as rocket drilling, explosive drilling, erosion drilling, arc drilling, plasma, turbine, high frequency, nuclear drilling, laser, electron beam, microwave, projectile, induction, ultrasonic drilling Rock and so on. According to the mechanism of rock drilling is divided into mechanical stress drilling, thermal flaking and melting gasification, and the use of chemical reactions such as drilling rocks. The new method of rock drilling, most are still in the experimental stage, the most effective or mechanical drilling method, such as diamond drilling.
