Hi Philip,
Thank you very much for that very fast reply! The document is from 1938,
which is old for Belgium -). It gives an overview (1870-1920) of the arsenic
industry in the Tamar district.
Regards from Antwerp,
Richard

Subject: Re: Looking for help on mining terminology
Hey Richard,
"The wall rock of the lodes was usually sound" means that the veinmaterial
in which the (metalliferous) ore was located were firm enough to support
mine corridors without the support of heavy mine timber.
Stopes are semi vertical veinlike deposits that were usually worked by
platform systems (if not reachable by hand). I think the method of back
stoping might have to do with backfilling dead rock to reach higher places
located on the stopes.
I haven't got a clue about the underhand, but if the text handles about old
mining methods it was usually by handrilling holes and gunpowder blasting
that ore was recovered. Underhand might refer to a special way of
hand-drilling??
About what timeframe are we talking about when you refer to as 'old' en in
which minedistrict in the UK?
Cheers from Leuven,
Philip

Hi group,
I received recently an old English text on mining. Being a bad student, I
don't understand all the terminology.
Is there someone on the list who can clarify this sentence?
...The ore was easily mined from the steep pitching veins by "underhand" and
"back stoping" methods. The wall rock of the lodes was usually sound. Single
stick timbering generally sufficed....
What does 'the wall rock of the lodes was usually sound' means?
What are 'underhand' and 'back stoping' methods?
Very kind regards from a area where no mining is...
Richard
