Strategy

Open the path down from the starting room:

-------------  A dddd d
|<|.....|..-- 
|^|.J.IH|...| 
|^|-K....E.-- 
|^||..G.-...| 
|^|---.--.A>| 
|^|  |F---.--
|^|  |.---.---
|^----.--....|
|..^^^..B..C.|
|??------..D.|
----    |...--
        -----

Push the boulders in that room towards the first three holes:

-------------  B lll*
|<|.....|..--  C llll lll*
|^|.J.IH|...|  A ulll llll*
|^|-K....E.--  
|^||..G.-...|  
|^|---.--..>|  
|^|  |F---.--
|^|  |.---.---
|^----.--....|
|..^^^..B..C.|
|??------.AD.|
----    |...--
        ----- 

Grab the scrolls of earth, then use up the remaining fourth boulder before opening up the left path from the starting room:

-------------  D ulll llll lllu*
|<|.....|..--  E d
|^|.J.IH|...|  
|^|-K....E.--  
|^||..G.-...|  
|^|---.--..>|  
|^|  |F---.--
|^|  |.---.---
|^----.--....|
|..^^^.......|
|??------..D.|
----    |...--
        ----- 

Once this is done, you have a clear path to deal with the next five boulders:

-------------  I drrr rddd dddl llll llll uu*
|<|.....|..--  H drrr dddd ddll llll lllu uu*
|^|.J.IH|...|  J rrrd rrrd dddd dlll llll lluu uu*

|^||..G.-E..|  E ulll rrrr dddd ddll llll lllu uuuu u*
|^|---.--..>|  
|^|  |F---.--  
|^|  |.---.---
|.----.--....|
|............|
|??------....|
----    |...--
        ----- 

Clear a path to push the final boulder in and complete the floor:

-------------  G l
|<|.....|..--  F dddl llll uuuu uuu*
|^|.....|...|  
|^|-.......--  
|^||..G.-...|
