It was at Snailbeach, at 192 yard level, as reported by Stephen Eddy in 1856.
He also reported that there was no pumping from below 192 yards then.
So this bob-plat, which Eddy writes in inverted commas, is a bit of a mystery.
Any thoughts?

Andy,
Underground it would be an area cleared so that a balance-bob or angle-bob
could be put in. The first to counteract the weight of the pitwork and the
second to change the angle of same within a shaft. Which mine was this for?

Thanks for that.
What might a bob-plat, not directly associated with an engine, be used for
underground?

Dear Andy,
The one Ken Brown and I used in our engine house book was (part in brackets
added):
One of two maintenance balconies cantilevered on either side of the beam
from the top of the bob wall of an engine house out to the end of the bob
[supported by the spring beams - a pair of large timbers extending from the
rear wall and used in conjunction with the main girder to prevent
overstroking].

Dear fellow Listees,
Can anyone give me a comprehensive definition of a bob-plat please?
Best regards,
