Two techniques (stone-splitters and demolition agents) are revealed to be efficient
methods for breaking large stone blocks in extreme paleontological excavation. In
certain conditions – where security factors, permission issues, terrain conditions,
rock properties are problematic – the traditional methods for breaking large rock
blocks cannot be applied (e.g. crane trucks or explosives). Using an expansive demolition
agent or stone-splitters after drilling equidistant holes not only allows a cheap,
quick and safe solution but also permits precise removal of up to 9 ton blocks.
Stone-splitters are a three-part tool that when inserted linearly and equidistantly
along a brittle rock mass cause a precise fracture.
