Drilling & Tunneling Engineering Is Advancing from Engineering Technology to Engineering Science

This paper mainly introduces the best advanced technology and application of controlled directional drilling technology, tunneling engineering and trenchless engineering, and demonstrates that the drilling and tunneling engineering technology is more advanced and scientific due to the developments of the exploration engineering, resulting in the rapid increase in the high tech association. In this sense, the drilling and tunneling engineering technology is not only considered as an engineering technology, but also more as an engineering science.
