Different Types of Drills Explained

 With the period of time, mining operations have become more prevalent to create new pathways through the rocks, different drill rigs have been introduced by mining equipment manufacturing companies. They have different features for accomplishing the mining tasks operated manually or automatically through a remote system. Also, they vary in shapes, sizes, functions, space, quarries, and other components to complete a mission of an operation.  In this article, we will be talking about some extremely famous and widely used types of drill rigs. Let’s have a look:

Surface Top Hammer Drill Rigs:

These drill have very powerful hydraulic drills along with a hammer. For an operation, the professional uses the hammer to strike the drill rod and produce a percussive force to displace the rocks while leaving them susceptible to water or air. The rig can work wonderfully even in the toughest conditions. When combined with a drill and a blast method, it makes the excavation process quite efficient.

Dimension Stone Drill Rigs:

This rig has a more abstruse function than various other drill rig counterparts it has. Professionals use the drill rig to drill precious holes in the ground to excavate natural rocks such as limestone, marble, sandstone, granite, etc. These rocks can be extracted and formed in different shapes of blocks for construction purpose.  It drills precise holes safely and efficiently.

Development Drill Rigs:

These rigs are actually modular mining vehicles used to drill holes into a coalbed surface. Through this rig, explosive can be inserted and denoted. These rigs can be transported, reassembled, and dissembled depending upon the needs. From small-scale mining to large scale tunnelling, the rig can be used for high efficiency and great results. 

Surface Down-The-Hole Drill Rigs:

The purpose of this kind of drill rig is to drill large-diameter holes downwards. The arrangement of the rig consists of a jackhammer which is screwed to the bottom of drill string. Like other rigs, DTH breaks up the rock, but it specializes in high-capacity rock drilling in rock excavation projects, opencast mines, and quarries.

Rotary Blasthole Drill Rigs:

It drills into the earth to create holes that later are filled with explosives to clear large sections of rock for subsequent mining operations. These rigs provide great depth, improve productivity, and make cost-effective choice of excavation.

In-The-Hole Longhole Drill Rigs

These rigs are mounted on articulated carriers to be transported into a mine where extension rods are used to drill holes. Among various types of drill rods like- Taper drill rod, Integral Drill Rod, shank rod, or extension rod, selection remains utmost concern to carry out safe operations. The ITH longhole drill rig removes debris through an extreme pressure of water. They provide high mobility and accuracy.
