I hadn't heard it was being reopened for these purposes. Awesome!<br /><br />Like Jack, a question. If it flooded with a couple inches of rain, how will they prevent it in the future when it is "the lab"?<br /><br />-LoriBeemerGirlhttps://www.blogger.com/profile/15239761274177026636noreply@blogger.comtag:blogger.com,1999:blog-1512448163402185409.post-46783551710586872522011-05-25T21:06:46.222-08:002011-05-25T21:06:46.222-08:00Jack / Reep:

There are several routes for the water from the pit into the mine through permeable rock layers. They have an elaborate pumping system to bring the water to the surface in stages with holding tanks at various levels. Otherwise the pressure required would be enormous. The same problem with water and sewage in large skyscrapers. The couple of inches of rain resulted in about 20 million gallons all of which needs to be run through the treatment plant. <br /><br />3) The water in and near the mine have arsenic due to the chemical process of extracting the gold from the pulverized rock. <br /><br />4&5)Yes, it gets denser as you go lower and I believe that your ears would "pop" as you descend. Even though the elevator will go up to 40mph, they only run it at a third of that when transporting people. <br /><br />This was a really interesting trip...RichardMhttps://www.blogger.com/profile/04773834892715980735noreply@blogger.comtag:blogger.com,1999:blog-1512448163402185409.post-18879826890677244332011-05-25T17:58:31.056-08:002011-05-25T17:58:31.056-08:00Dear RichardM:

While you alluded to arsenic and iron, you also mentioned flooded tunnels due to rainwater. <br /><br />1) If the elevatir shafts are covered, how does the rainwater get into the mine?<br />2) Is most of this rain water or seepage? Wouldn't it be just like a giant well?<br />3) Is the water pure, or is the water table loaded with arsenic?<br />4) Air gets thinner the higher you go. Does it get denser as you get lower?<br />5) Do your ears pop in reverse?<br /><br />I realize you didn't get down into the mine, but I wondered if any of this came up in construction. <br /><br />Very interesting.<br /><br />Fondest regards,<br />Jack / Reep<br />Twisted RoadsJack Riepehttps://www.blogger.com/profile/07531160098262862027noreply@blogger.comtag:blogger.com,1999:blog-1512448163402185409.post-45040071249345916062011-05-24T19:39:57.416-08:002011-05-24T19:39:57.416-08:00I'm still very interested in physics and tryin...I'm still very interested in physics and trying to learn the new material since I got out of school (physics degree).
