Description

Conventional Explosive Method

Rock Splitting Method by Hydraulic Pressure

REM Rock Splitting Method

Principle

Using expansion force of gases radial cracking by shock energy (Organic nitrogen oxide)

Using hydraulic pressure

Using expansion force of solids
(Inorganic rapidly expansive metal mixtureradial cracking by shock energy)

Activated by

Detonator

Hydraulic pressure

High voltage spark

Safety

-	Sensitive to heat, shock and friction
-	May be used for malevolent purposes other than those intended by its design

-	In the case of breaking hard rock, chance of the hose bursting due to hydraulic pressure is great

-	Safe from heat, shock and friction
-	Cannot be used for malevolent purposes other than breaking rock and concrete

Impact on Environment

-	Vibration, noise and fly rock are generated
-	When exploded in the open air, it causes direct impact on the surrounding environment
-	Most likely to provoke general complaints

-	No vibration, noise and fly rock
-	Severs noise is generated from drilling equipment
-	Few general complaints

-	Very low vibration, noise and fly rock
-	When ignited in the open air, no direct damage is caused since it is not exploded but combusted
-	No toxic gas

Handling

-	Explosives can only be handled by a licensed explosive handling technician
-	Fatal accidents may occur due to explosions caused by low current in the detonator

-	Rock breaking preparation is difficult due to the heavy weight of the rock breaking rod

-	Operator dose not require a license.
-	Low current ignition is impossible

Workability and Economical Efficiency

-	Difficult to work near a structure
-	Prearranged planned breaking is possible
-	Daily breaking capacity: More than 200㎥

-	Possible to work near a structure
-	Low work efficiency for hard rock and weathered rock
-	Low working speed due to large hole drilling
-	Dail breaking capacity: 30-60㎥

-	It is possible to work near a structure
-	Prearranged planned breaking is possible
-	Daily breaking capacity: More than 200㎥
