Aboveground Drilling DRL
April 2011 – Present.
Upon successful completion of the course, students will be able to: list six different types of drilling applications and identify the appropriate type of drilling technique needed in each application; identify the most common types of aboveground drilling equipment and describe their uses; identify at least three aboveground drilling job site hazards and methods to control each hazard; list the health hazards of aboveground drilling and describe a method to control each hazard; identify and demonstrate the use of personal protective equipment (PPE) needed for aboveground drilling work; identify the class of several types of explosives; name the categories in the Bureau of Alcohol, Tobacco and Firearms (BATF) explosive classification system and give at least one example of a material in each category; identify the appropriate safety precautions for storing, transporting, handling, protecting and drilling around explosives; give examples of at least three tools that are powered by compressors; identify the components of airlines and fittings and demonstrate methods for connecting and securing them to tools and other fittings; list at least three precautions to take when working with a compressor in extreme temperatures; using a set of typical compressor problems, match troubleshooting checks with each problem; describe three types of drilling; identify the principal components of a drill string and describe the purpose of each; identify at least three drill bits and describe where they work best; list two causes of “bound steel” and at least one method to prevent each; describe and demonstrate the steps to “collar a hole”; list at least three factors that affect proper alignment of a borehole; describe and demonstrate the steps to add drill steel and remove drill steel from the drill string; describe at least two problems that prevent the flushing and removal of cuttings and at least one method to prevent each problem; describe at least two maintenance or critical operating practices that will prolong the life of the drill string; describe and identify the three most common types of rock; describe at least two types of borehole patterns and demonstrate how to lay them out; describe the safety hazards associated with operating a jackhammer and give at least one method to control each hazard; identify the components of the jackhammer’s lubrication system and demonstrate the proper lubricating procedures using the proper tools, materials and equipment; identify four types of bits used with jackhammers and give descriptions of each; demonstrate operation of a jackhammer; describe and demonstrate techniques for collaring and drilling a hole; explain the purpose of clearing cuttings from the borehole; and list five common problems that occur when drilling with a jackhammer.
Major topics include: the care and use of tools and equipment, as well as drilling techniques. Basic information about rocks and their composition and characteristics is introduced, as drillers must know how geology affects the drilling process. The personal safety of CCL's working on a drilling site is reviewed in depth. Site safety, health hazards, personal protective equipment, and working around explosives are also covered.
In the associate/certificate degree category, 2 semester hours in Construction Technology (4/16) (4/21 revalidation).
