====== Mine Entrance ======

===== Notes =====

* This tutorial assumes that you already have your entrance tiles prepped; all of the tiles surrounding and including the entrance tile have been dug down to rock.
* Tunneling in creates a new entrance with a 20 ramp slope down.
* Improved compass and tool tip mods will help you with corner height.
* For the best results, I use 30 or 33 slope between top and bottom corners of the entrance tile (outside) depending.
  * 30 is the default height (slope) from floor to ceiling if mining forward.
  * If you're considering having buildings in your mine, 33 is the default height height (slope) of a first floor of a building from bottom to top.  Subsequently it is 30 for floors 2 and up.  This is wall height and doesn't take into account the height of a roof.  Roof height if the width of the roof is 1 tile is 20 slope high. Roof height if the width of the roof is more than 1 tile (vaulted ceiling) is 38 slope high.


===== How to Make a Flat Entrance =====

Method 1:

* Align the floor and ceiling corner heights (inside) with those of the entrance tile (outside). Mine out from the inside.  You should now have a flat entrance.

Method 2:

* Tunnel in, which puts you down 20 slope, tunnel up the next tile inside (reversing the 20 slope), then mine one tile in to get a flat tile.  Fill in the down and up slope tiles, then mine straight out.  You should now have a flat entrance.
