With changing times and the
introduction of newer technology construction of buildings, roads, dams,
tunnels became easier. With passing time rock blasting required to do all of
the above mentioned also became easier. Man first learned to use explosives for
breaking down big rocks, later he invented equipment, tools and techniques that
let him do the same without using explosives. Gunpowder was originally used as
an explosive way back in the seventeenth century. At that time it was basically
used for mining.
Rock Blasting With Non Explosive
Techniques.
There are several equipments and
tools that have helped do away with the vintage methods of rock blasting. Some
of these tools are, frost wedge, hydraulic crushers, Pulverizers, shears, asphalt tool, super blunt tool,
fluted tool, Chisel tools, Moil tools, Rock
breaking hammers, tamping
tool, Rock breakers, Booms.
Hydraulic compactors,
Concave Removal Tool, deck buster tool. The chisel tool is used while working
on soft to medium hard rocks. The moil tool is especially effective for weak
metamorphic and sedimentary rocks and is used for concrete breaking , tunneling
and trenching. The use of a blunt tool is advised for highly abrasive working
conditions e.g. for breaking an oversize rock needing a maximum fracture.
