HIGH PIT WILMA 413 Posted March 21, 2021 Report In the confines of a coalface,sometimes you couldn't start with a 6-0' drill straight off,so you had to start with a 3-0' drill,then change to the 6-0' one when you had drilled right in with the shorter one.That's why he has one lying beside him. 1
HIGH PIT WILMA 413 Posted March 21, 2021 Report In some seams,thi coal was like diamond,hard as hell! At Bates,there was a lot of Iron Pyrites,["Brass"..Fools Gold..!],and if you hit some of this,it used to take the Tungsten Carbide Tips off the Drill Bits!...Noo THAT is HARD!.
