Different Environmental Methods of Rock Excavation

by admin

Economically, blasting is used in mines for rock excavation. However, when the explosion occurs, the explosive energy changes into other energy sources. One is elastic wave energy, resulting in ground vibrations, which may cause damage to the nearby buildings. Also, toxic gases are produced, which destroy our environment. 

 

As a result, it is crucial to know the proper methods of rock excavation to overcome environmental disturbances. 

This post will share different environmental methods of rock excavation in Sydney to perform this job properly. So, without any further ado, let’s get into it! 

Why is there a need for rock excavation? 

Australia holds some world’s most ancient geological structures. These rocks, usually excavated, dating back over 3000 million years. Some documentations show that the remarkable zircon crystals go back at least 4400 million years and are found in much younger rocks.  

Types of Rocks 

Sedimentary rocks: Sedimentary rock is a relatively easy rock to work with. Sandstone is a sedimentary rock form. 

Metamorphic Rocks: These rocks are often harder to extract because they are prone to fractures and cracks. 

Igneous Rocks: These can be easily the most challenging to excavate but also the rarest. 

The oldest rocks are sandstones deposited by ancient seas, followed by sediments such as shales and siltstones formed from the weathering of sandstone or by volcanic eruptions at the end of the Paleozoic era.  

Sydney is mainly built on sandstone, so rock excavation in Sydney, rock bearing, and thawing are very common for construction purposes. 

What is involved in the rock excavation process? 

Many stone structures are too large, heavy, and thick to be carried by hand. Instead, they must be removed from their transport site to a worksite where they can be lifted and moved on skids or trailers to another area for removal and reuse as fill or landscaping material. 

In particular, the construction of walls or floors is typically done using large and heavy machinery to form a trench into which the stones are placed. Therefore, rock excavation in Sydney requires special equipment and methods.

Why is rock excavation important? 

Rock excavation is significant for remodeling a landscape and constructing many of its characteristics. The technique for excavating rocks differs from the method for excavating standard soils. Specialized workers and specially designed tools and equipment are required for digging the rocky terrain, as it needs expertise and experience. 

Different Methods of Rock Excavations 

  • Blasting
    Blasting is the calculated use of explosives to excavate rocks while constructing anything on rocky land. Engineers have used this process of rock excavation for a long time.  

  • Drilling
    Cracks and blasting holes are drilled so the rocks can be easily trimmed into desired shapes and sizes. This rock excavation method is usually used after blasting or when the rocks aren’t too hard. 

  • Ripping
    Ripping is the act of demolishing rock & soil using a sizeable pointy needle attached to the back of a bulldozer. It is highly cost-efficient, saving almost 50-60% money compared to blasting. 

  • Breaking
    It is done using a hydraulic hammer fitted on the top of the excavator. So the arm of the excavator will act as a structure to break concrete.
