I have killed the ice monster, but can't get
 the ice blocking tunnel to break by using the 
 urgon part.
  
 
  
  
    Stand right in front of the iceblock,
 get your Urgon's Part and push Control.
 Should work. 
 
 Good luck,
 
 Robert Beckmans.

    And if it not works, I have a saved game for you just after breaking that iceblock
