Talk:Underground hard-rock mining

message: I would like to see some pictures, if anyone has any, of some of the machinery used in hard rock mining. Thanks!--Candy 18:02, 2 November 2005 (UTC)
thread_title: (Early comment, heading added later)

message: Could someone who knows please explain the "Ore extraction" and "Hardrock mining terms" sections in words that readers unfamiliar with mining can understand? Thanks. --Scott Davis Talk 12:42, 7 October 2006 (UTC)
thread_title:  Terms need explaining 

message: I removed the section (one line) on open pit mining as there is an article devoted to it

thread_title: Trying to clean up

message: There should probably be a whole article on this, but in the meantime I've put a picture in. It's probably worth having a picture of something underground, after all!Riedquat 19:24, 18 April 2007 (UTC)
thread_title:  Ventilation 

message: Is it really necessary to have the (hard rock) behind this? I'm a geologist, so maybe I'm talking out my rear as usual, but the process of mining hard rock and 'soft rock' is basically the same until you cme to longwall mining of coal, and its various derivatives. Is it better to not find ome way to name this page which is based on the processes distinct from longwall mining or retreat mining of coal? Rolinator 09:31, 22 August 2007 (UTC)
replies: text: Not necessarily the same, i.e. using a continuous miner to mine salt.  I agree it is a little somewhat unnescesary (I'm the one who moved it :S), I was just trying to distinguish it from coal/other material that is not mined with traditional "dril and blast" techniques, as they are quite distinct.--Kelapstick 10:49, 22 August 2007 (UTC)
replies: text: I've heard "hard rock mining" used in the same way (although I'm not sure, now I think about it, if any of the people I've heard use it are or were actually miners - I'll have to try to remember to ask a miner some day), but I don't know how accurate it really is, or, perhaps more importantly, how much of a distinction the industry has, and the fact that I view underground quarrying as possibly more like hard rock mining makes me wonder just what criteria I'm thinking with!

thread_title: Definition?

message: I am about to overwrite  Glory_hole_(mining) with a redirect to the section that it lks (via Rdr) to in the accompanying article. I don't want to understand mining well enuf to decide whether the only quasi-'graph among the material i'm overwriting, to wit 
: * In the block caving method of underground mining, ore collapses from above into a mine tunnel.  If enough ore is removed, the ground surface collapses into a surface depression called a glory hole.  Examples include the Climax and Henderson molybdenum mines in the U.S. state of Colorado
merely summarizes the section it lks to on the accompanying article (and can thus be discarded along with the dictdefs that make up the rest of the page i'm overwriting), or deserves to be partially or fully merged "here". Perhaps a colleague with more background will make that call, and so note on this talk pg.----Jerzy•t 22:19, 14 June 2011 (UTC)
thread_title:  Glory holes 

message: In the article, there is a short description of Block Caving, but Wikipedia does not have an article about that particular mining method. What critera does a mining metod need to meet in order to be considered notable? For example, consider sublevel caving mining. This mining method is used at several mines around the world, and in one of them (LKAB Kirunavaara) it is used in a mine employing thousands of employees, in a mine which takes up more than 10 million tons of ore yearly. Is that notable in and of itself?
If sublevel caving mining were to be considered worthy of a wiki article, I could write up a description of it. To do so, I would just have to copy relevant parts of my PhD. thesis. The original research part of my thesis covers highly technical details of sublevel caving, the description of the mining method would be stuff that was already widely known to many people in the field of mining. Would that run afoul of wiki rules? 46.236.70.107 (talk) 22:31, 15 August 2011 (UTC)
replies: text: Such an article should be notable. However, simply copying parts of your thesis likely wouldn't work. This is an encyclopedia not a dissertation and what is the copyright status of your thesis? Now, you are welcome to start such and article written as an encyclopedia article and using your references from your thesis work in support. Please create a user account and look over the relevant policies around here. Drop me a note on my talk if you have questions. Vsmith (talk) 01:59, 16 August 2011 (UTC)

message: Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted.
Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia.
This, however, doesn't necessarily mean it's spam, or not a good link.
If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting.
If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page.
If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta.
When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags.
The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true.
Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.
