hello I'm Ken Johnson with Virginia
energy and this is your mind safety
minute one of the most important aspects
of underground mining is roof control
to achieve our safety goals we need
effective roof control plans and to make
sure we periodically observe the mine
roof
this can be achieved with the help of a
borescope this is a device that shows
you the whole borehole it can alert us
to separations cracks water and small
coal seams in the mine room
this helps us make decisions to ensure
our roof is supported throughout our
operations
