  • For mining drilling rig selection, our target is choosing the right rig for right purpose, let’s have the further explanation on how to achieve this target. 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 drilling in open cast mining Other drilling in open pit mines like wall stabilizing, roads, foundations for...

  • 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. Top 1 SANDVIK SANDVIK is top player for drilling rig for Mining and Water Well and Construction Drill Rigs. From working principle, there are Surface...

  • In last article Mineral Commodity Summary, the general analysis for most type of mineral are done. Today, let’s have a look on Iron Ore. Classification of Metals Iron and Ferro-Alloy Metals (Eisen- und Stahlveredler): Iron ore, Chromium, Nickel, Cobalt, Manganese, Molybdenum, Tantalum, Niob, Vanadium, Tungsten (Wolfram) Non Ferros Metals...

  • 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...

  • 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 Ratio?                           The sink ratio which related to depth of air water...

  • 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 for big diameter hole. Reverse Circulation(RC) Working Principle The drilling theory of air reverse circulation is similar with the theory of drawing water with air compressor. The air flows down the annulus between...

  • 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, it is one time investment. The machine’s price increased along with increasing of hole diameter and depth. From...
