Boring 2 Pdf This chapter describes the basic methods for engineering geology core logging and provides examples and instructions pertaining to format, descriptive data, and techniques; procedures for working with drillers to obtain the best data; caring for recovered core; and water testing in drill holes. The boreholes drilled by the core boring in the model rural areas were enlarged to at least 8.5 inches by re drilling to be able to install casing pipes and screen pipes. The section entitled “core recovery and core losses” contains instructions for proper use of core measurements, filler blocks (spacers), and tape checks. the driller is responsible for knowing the depth of the barrel and the hole at all times. Rock core should be fully described on the boring log. typical rock core parameters are shown in table 4 2. for rock core, a scaled graphic sketch of the core should be provided on or with the log, denoting by depth, location, orientation, and nature (natural or coring induced) of all core breaks.
