Jesus is still in the grip of the deep emotion described in verse #33 as He approaches the tomb of His friend. Calvin sees in this the cost of working a miracle when he notes that, “Christ does not come to the sepulchre as an idle spectator, but like a wrestler preparing for a contest.”

John 11:33  When Jesus saw her weeping, and the Jews who had come along with her also weeping, he was deeply moved in spirit and troubled.

The resting place of Lazarus is a cave, which was quite common in those times, with a stone laid across the entrance to keep out the wild beasts. We are not told if the cave had a vertical or horizontal opening, but further on we see that Lazarus comes out under his own power so the opening was probably horizontal with a large round stone rolled over the entrance.
