Thank you very much, if they publish a dictionary about civil engineering we might suppose that this information is quite reliable I guess ;-). Sand is used for grain sizes from 1/16 mm to 2 mm, silt would be 1/256mm to 1/16 mm and clay is below silt (smaller then 1/256 mm or 4 µm (2 µm)). As they speak of fill and fill is just defined by it's usage AFAIK (comprises all smaller grain sizes), we might not have a problem by using quarry for clay pits as well (subtagging quarries as clay_pits). cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

The main difference between quarry and open [cut|cast|pit] mining is the scale... quarries tend to be on the smaller end of the scale, where as open cut mining can be quite large... I thought that there was no doubt that quarry is a type of open cast mine. I read this in different sources. Of course if you say open cast mining nowadays, (beeing a generic term) you will be presented the most spectacular types where other words do not exist, while for a quarry you would search quarry, even though it is a type of open cast mine.

Re: [Tagging] quarries in engineering
Pea gravel is mined from river and stream beds. Crushed-stone gravel comes from quarries. The latter type is commonly used in concrete (pea gravel is sometimes used in a surface layer). I am not an engineer, but I do live near a gravel pit. ---Original Email--- Subject :Re: [Tagging] quarries in engineering From :mailto:richard.mann.westoxf...@gmail.com Date :Fri Nov 05 10:05:01 America/Chicago 2010 Gravel/sand/clay come from river beds, generally.

I would like to know (besides what wikipedia:en states), whether gravel pits are comprised in quarry. I'm quite sure that rubble is inside quarry, but am not sure for gravel. 2. What about sand and clay. Do they come from quarries? cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging Sent from my Verizon Wireless BlackBerry ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

I know that these are all open-cast mines, but the wikipedia entry for quarry seems somehow not precise enough when it comes to delimiting the usage. i'd consider it acceptable usage in the context of OSM. it might initially confuse someone who had never considered the question before but then there's lots of stuff in the osm wiki like that. the operative issue is that you're digging a hole or excavating the side of a hill or something to access mineral resources. that's quarrying. richard ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

2010/11/5 Richard Welty rwe...@averillpark.net: it might initially confuse someone who had never considered the question before but then there's lots of stuff in the osm wiki like that. while that is true, I still hope we can do better now and in the future. the operative issue is that you're digging a hole or excavating the side of a hill or something to access mineral resources. that's quarrying. yes, but under water? Usually quarries try to get rid of the water if there is some, but I'm not sure if this is part of the definition or it is just a misconception on behalf of me. The question about the clay is headed towards the grain size. Basically stone and clay are the same, it's just the grain size. Still quarry might not be a generic word for this --- or it might be. cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
