摘要

Completing bores in rock can be one or the most satisfying accomplishments of a hori- zontal directional drilling contractor. It makes no difference if you are the contractor with the 10,000- or 12,000-lb drill or the company with the 1 million plus-lb drills. Both sizes and everything in between have the same opportunity to bore in rock. We have all heard about the 3,000- and 4,000-plus ft bores that have been completed in conditions that, according to the experts, could not be drilled. These projects were successfully completed because the contractor spent the time to learn about everything he could about the job including site and soil conditions. The successful contractor spent time planning every part of the bore. He eliminated every strike he could before he ever turned a key on the truck to head to the site.
