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 these series article, we will introduce the key knowledge on blast drilling according to our many years practical experience in Hardrock Drills. Below is the lecture overview which will be introduced item by item, today we will start from Modern systems for surface blasting drilling.

There are totally two parts for this topic, here is the part one. Field of Application OPEN PIT MINING (METALS, INDUSTRIAL AND BUILDING MATERIALS) Production drilling Pre-split drilling Overburden […]

For borehole drilling, it looks simple. But if you really want to get perfect borehole, it will need a lot of professional knowledge. Such as selecting most suitable drill rigs and drill tools. Any of them is not chosen properly, it will cause issues on hole quality. Below is some tips we learned in the […]

In the world, there are  hundreds of player, who making the Drill Rigs from 1 century ago. However, along with marketing competition and technology upgrading, less 10 drill rigs suppliers are leading the drill rig industry developing. We will give short introduction on their great strength and hot products for these rig manufacturers  in below. […]

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:        […]
