Hey guys,
This is the second part of the job following on from the evap pond in the previous post. Reopen the exsisting decline for the underground mine and add a lift to the exsisting tails dam. The dam was built in 2 stages, 1st was to lay in the Zone 1 material - which consisted of mainly overburden and rock, the Zone 2 was to lay in tails from the old dam on the inside of the Zone 1 material. So really to put it simply built 2 walls with 2 to 1 batters and butt them up against each other. Rock to hold the weight of the wall up and tails to seal the dam so as not to line it. Enjoy.
