Type: Latent image Audience: Remote control and extended cut miner operators and face crews Length: Eight questions (30 minutes for administration plus 30 for discussion) Skills: Remote control mining procedures including remote control mining, taking extended cuts, resetting breaker on mining machine, and setting timbers. Communicating mine conditions, influencing safe behaviors when mine conditions are less than stable Location: Underground coal mine, four section continuous mining operation Average seam height is 48 inches Problem: Your regular job is on the general labor crew at Cripple Creek #9 mine, a four section continuous mining operation. The mains are 9 entries wide and panels are 5 entries across. You and the rest of the crew had annual refresher training about 3 months ago. For the past few days you have been sent to 2 South panel to fill in as the third shuttle car operator. This morning, however, your buggy is down. The face boss asks you to get the scoop and take seven or eight timbers to the number 5 entry because the last shift got off sight line. The miner will be working in entry 5 while the bolter crew pins entry 4. When you get up to the face you see that Mo, the remote control continuous miner operator, has rounded off the left inby corner in order to make his first cuts in the right hand rib. Now, he has squared around enough so that you and Red, the miner helper, can set some posts on the corner. The two of you set posts along the left inby rib of #5 entry while the shuttle car operator waits. You are in a tight spot when Mo decides to start mining. You must decide where the best place is to stand for safety and to be out of the way.
