I would also like to add that the hole it itself is not going  directly downwards and has had a change in course, as seen here:

With the Elicitor now tunneling beneath the ground, the navigation officer adjusted course to direct the fortress towards the demonic controlled territory. Its console was locked soon after

Indicating that there is likely not a straight shot to be had down the hole, as the Elicitor itself changed direction due to demonic infiltrators.
