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.

In the world, there are  hundreds of player, who making the Drill Rigs from one century ago. Their drilling machine cover almost all drilling business, such as blasthole drilling, water well drilling, geothermal drilling and solar piling drilling as well as construction borehole drilling etc. However, along with marketing competition and technology upgrading, less 10 […]

The DTH hammer bit is very widely used for bore hole drilling including Foundation Drilling, Water Well and Mining Drilling. Therefore how to select proper drill bit is the key technology for each borehole drill operator. If we want to do this the, we must know the different characteristic for different drill bit type. For […]

Rotary drilling tricone bit is essential for Borehole Rotary drilling such as for Piling Drilling, Foundation Drilling, Mining Drilling, Oil/Gas Drilling and Water Well Drilling. Normally it works with mud pump or air compressor as drilling fluid to take the cuttings out of the hole. Classification in terms of amount of rollers:        […]

In last article, 6 advantages between direct circulation and reverse circulation drilling is explained from application point of view, here will be some key point for how to design the reverse circulation drilling system. There are total 7 points the designer should care to get a perfect RC drilling system 1. How to Define Sink […]

In last article 8 Points on How to Select Water Well Drilling Rig, the Drilling method are mentioned, here we will give some further introduction on reverse circulation drilling system. The RC is widely used in borehole drilling area especially in water well drilling and foundation drilling for big diameter hole. Reverse Circulation(RC) Working Principle The drilling theory […]

For water well drilling rig,the general requirement: simple configuration,less energy consumption,easy operation,more moveable,  Muti-functional, small size. In real application, the drilling rig selection has to be based on the stratum, hole diameter and hole depth as well as drilling method 1. Price Machine price is the key factor for people to select suitable drilling rig, […]
