EE was installing roof bolts outby the #2 Face on the 2-W CM section. While using the machine head to push a bolt up into the previously drilled hole, the bolt became stuck. When EE applied extra force to the bolt in an effort to push it up fully, the bolt bent causing the bolt wrench to come off and struck EE above EE's left eyebrow causing a laceration. EE received 8 sutures.
