300 meters underground

Quarry:



Actually careers - not a very interesting place, deep in the rocks is much more interesting object, so the process was conducted through the teleportation of an earth formation.



Teleport quite well, hence the start our way up to 300 meters deep:



Once upon a time in this place exploration magnesite deposits were discovered - abundant mineral, magnesium carbonate.



Magnesite - a valuable raw material for the steel industry, it is used for the manufacture of refractory bricks.



Also magnesite - a raw material for magnesium and magnesium-based alloys are important structural materials in aircraft and automobile industry due to their lightness and strength.



But sooner or later, due to the performance of career geometric features decreases and reaches a point where it becomes unprofitable, and stocks of raw materials underneath it quite yet. Then begins the construction of mines.





The descent is completed, where the fun begins.



This unit in the rock punched a small hole diameter of a few centimeters. They lay an explosive charge for sinking and inserting fasteners for the construction of communications.



And since this unit appears on the reverse side:



The machine, which is a huge bump:





Garage and workshop rolled into one:







Well, we'll go on to the face. Unfortunately, we could not reach because of the blasting.



For shipment breed long tunnels were pierced directly into the bottom of the quarry, laid narrow gauge railway:





Every 15 minutes flying ghost train with ore:





During turn - out back to the quarry.
