1, Bucket-type earth-boring drills of various types have been utilized. Conventionally, the buckets have cutting blades on their bottoms and are provided with bottom openings to permit relatively small rocks and objects to be received into the bucket.
2, Upon encountering a relatively large rock or other object, a common practice has been to remove the drilling bucket from the bore being drilled and to lower a rock bucket particularly designed to be repeatedly dropped upon the rock or object.
3, After the rock has been broken into pieces by repeated impacts of the chopping bucket or rock bucket, the chopping bucket is removed from the bore being drilled and is replaced with the drilling bucket which is capable of receiving the smaller pieces through its bottom openings.
4, This conventional technique of utilizing a chopping bucket is characterized by certain disadvantages and shortcomings. Among these is the fact that considerable time and labor have been required in breaking up and removing rocks in this manner.
