This document specifies the specific safety requirements for drill rigs for civil engineering, geotechnical processes, geothermal energy, ground exploration, mining, quarrying and water wells for use above ground as well as underground when used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. In this part 2 of prEN 16228 these machines are referred to as drill rigs. In this document the general term “drill rig” covers several different types of machines for use in: civil engineering; geotechnical engineering (including ground investigation, anchoring, soil nailing, mini-piling, ground stabilization, grouting); - water well drilling; - geothermal installations; - landfill drilling; - underpinning, tunnelling, mining and quarrying; - for use above ground as well as underground. Typically the process of drilling involves the addition of drill rods, tubes, casings or augers etc, normally threaded, as the borehole extends to depth.This document does not specify requirements for the movement of drill rigs on public highways except when carried on a trailer or other transport vehicle. Three drilling principles are currently available - percussive, rotary and vibration. Combinations of these principles are also possible e.g. rotary percussive. Percussive drilling is a method by which the hole is produced by crushing the ground or rock at the bottom of the drill-hole by striking it with the drilling tool and removing the cuttings out of the borehole.Rotary drilling is a method in which the drilling tool at the bottom of the borehole is rotated and at the same time, a feed force is applied by a feed system or drill collar. The ground or rock at the bottom of the borehole is crushed or cut by pressure, shear or tensile stress produced by the different drilling tools. The cuttings are periodically or continuously removed out of the bore hole. Vibration drilling, sometimes called “resonance” or “sonic” drilling, is a method by which the hole is formed by transmission of continuous compression waves through the drill rods which fluidise the ground immediately adjacent to the drill bit. Rotary percussive drilling is widely used and is performed by a piston striking directly on the bit (down the hole hammer drills) or by percussive energy transmitted via a drill string to the bit. The piston is powered by either hydraulic fluid or compressed air. At the same time the drill bit is rotated either continuously or intermittently. The cuttings can be continuously removed out of the borehole by a flushing medium, which is carried to the drilling tool. The requirements of this part are complementary to the common requirements formulated in prEN 16228-1. This document does not repeat the requirements from prEN 16228-1, but adds or replaces the requirements for application for drill rigs. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of drill rigs.
