Rock excavation is usually carried out with the aid of blasting. So far this technique has been regarded the most effective way to drill rock. However as you move the blasting is done it causes large amount of noise and generates great shock. This is highly unsuitable for that neighbourhood. While heavy machineries works extremely well for excavation where population is scanty construction companies have to think of an alternative when the particular excavation work is community residential areas.
Today we have the low explosive items that minimize the risks of vibrations and flying rocks.

Here is the direction they are made and do the job:
• There are cartridges that are pyrotechnic products based on the non-detonating propellant that is again enclosed with a plastic case.
• For starting out the excavation work the particular cartridge is initiated simply by an in built safety electrical igniters. These igniters meet the standards of Class 3 blasting caps.
• The initiation machine initiates the cartridge. The cartridge is enclosed from the hole created on the top of rock.
• High gas pressures are initiated with the aid of the propellant and the particular rock is broken.
• Depending on the feature the site excavation work there are various kinds of cartridges to choose from.
Presently there are many options when we consider the particular rock excavation methods. Construction companies can perform their excavation jobs rather easily.
