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.
