Novel drilling system for cost effective extraction of the 30 million tons of ornamental stone blocks in Europe with lower environmental impact.

Objective

The main objective of the project is to develop an innovative water powered Down-the-Hole hand-held hammer for quarrying of dimensional stone. The enabling technology is a novel and cost-effective deposition of a water and wear resistant Diamond Like Coating on the percussion piston/cylinder sliding surfaces. The principle innovation is the development of a water powered DTH Hammer capable of drilling straight holes with increased energy efficiency, reduced levels of noise and vibrations as well as full capture of micro-metric particles through the deposition a novel water and wear resistant coating technology.
Main innovation of the coating concerns the deposition through remote plasma discharge that allows a low deposition temperature thus decreasing residual stress and providing unique water resistance properties. Further novelty is provided by the special mixture of gas precursor that enables the formation of friction sites that establish the unique frictional behaviour of the coating.
