Thanks for sharing the dictionary If you look at the entry for ademado, it provides "well casing" for Mexico. So this does indeed seem to be a specific use of the term in that country.

This is Mexico, for what it´s worth ... And yes, there were a few particular Mexicanisms in the text, so it could be a rather special use of the term here

cased drill holes Sergio is right. Cased would make more sense in this context. It would be helpful if you stated which country source texts are from, as the technical language can vary quite significantly.

Where did bracing come from? Robb's Diccionario para Ingenieros has shore and timber for ademar. Which dictionary said bracing?

Justin Peterson (asker) Mar 4, 2013:

Thank you * I went with "bracing" These technical terms are often really tough, as they depend on the specifics of the "obra" in question, the region, etc. I had to make a decision and call this "bracing" as per definition in a technical dictionary

I'd fully agree with Nikki's option if "ademar" referred, for instance, to the shoring of the tunnel itself, but in this particular context, this "ademado" is a sleeve (metal pipe) fitted into the blast hole to prevent it from collapsing. This is a small diametre hole (114 mm) that has to be kept open and unobstructed so it can be filled with explosives. I am wondering if something like "drill/blast holes will be cased" would be more appropriate in English in this case.
