And often this process is used to sculpt different landscapes. This process is also used to do away with a large amount of soil to make room for the foundations of different structures. On the basis of the hardness and depth of soil, it becomes necessary to reinforce the trench while removing the soil.

Blasting, breaking, and ripping are the most popular methods used for rock excavating. And this process has been an important part of the construction engineering till several years. The geographical constitution of the rock mass is considered to be one of the most vital considerations in any blasting condition.

And this type of blasting is loaded lightly with scattered charges. As a result, a stable and cosmetically appealing perimeter is created. So, this process is performed on slopes several years after the first construction. Besides, here the drill-hole traces look less noticeable than pre-splitting. And this procedure can be performed perfectly incompetent, hard rock. Due to the small diameter borings, the depth of this blasting is limited to 15m.
  2. Presplit blasting:This type of blasting is performed before the production blasts. This process uses smaller diameter holes at little spacing. And this type of blasting is loaded lightly with dispersed charges. This method is often preferred as it guards the last cut by making a fracture plane down the last slope face. Besides, this process can also create sharper cuts with the issues of less maintenance. And this process also perfectly performs in the stiff competent rock. Due to the smaller diameter borings, the depth of this blasting is limited to 15m.
