The product known as Extension rod, has many other names such as Extension drill steel, Extension drill rod, and Extension steel, M/F rod ( Speedrod ). It produces either hexagonal or round cross sections. Hexagonal rods are more rigid, heavier and it transfers energy more efficiently compared to round rods, while increasing flushing. On the other hand, round rods are usually lighter in comparison and are normally used in extension drilling applications.
Carburization is a heat treatment used to strengthen high speed and powerful percussive drill string components. It helps to maximize their performance and reliability.
The process involves increasing the carbon content of the material to harden its entire surface on the inside as well as on the outside. This helps to strengthen and extend the life of the rod.
Carburization is used for the Extension Rod and M/F steel process, by providing enhanced life to the component in a controlled manner.

Underground mining is a type of mining where extensive underground tunnels, drift, or shafts are used. This type of mining is used when ore or minerals are found deep within the ground. To reach the minerals, drifting and tunneling are often used, whereby horizontal tunnels are created deep within the ground. Benching is another common type of underground mining which is used when the ore is close to surface. This type of mining involves slicing the edges of the ore at different bench levels and using a series of long drill holes to extract the ore. Lastly, quarrying is a form of mining that is often used when the ore is close to surface. Quarrying involves mining the ore in an open pit.
In conclusion, underground mining is a type of mining that typically uses tunnels and other methods to access ore or minerals that are found deep within the ground. Drifting and tunneling create horizontal tunnels, benching uses slices of ore at various bench levels and long drill holes to extract the ore, and quarrying is used when the ore is close to surface and involves an open pit operation.
