The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.

Continuous mining machine - Mine Safety and Health ...

2010-6-24 · Coal production was completed in the No. 3 and No. 1 entries and Continuous Mining Machine Operator, Bobby Smith Jr. (victim), began mining in the No. 4 entry. After completing the cut, Smith made a clean up run along the left side of the entry, and then repositioned the continuous mining machine for a clean-up run along the right side of the same entry. At approximately 1:15 p.m., while making the right side-clean up run, he turned the front (inby) end of the continuous mining machine to the left. This resulted in Smith being caught between the right rear corner of the continuous mining machine and the coal rib. Smith was discovered by Thomas J. Campbell, Shuttle Car Operator, pinned by the “cable extender” (a strain relief for the trailing cable and water hose) at the right rear corner of the continuous mining machine
