BoreHole Drilling Knowledge

In order to share our drilling knowledge to people who are interested in borehole dirlling. Here are introduction and application cases regarding water well drilling, geotechnical drilling, foundation drilling and minning exploration drilling. It also introduces the drilling method of rotary drilling, DTH(Down The Hole) Drilling and Top Hammer Drilling. The basic knowledge of drilling tools and rock are demonstrated as well.

We hope this kind of drilling knowledge could be helpful for our customers, friends and peers working in borehole drilling area.
