Method and system of coal mine roof stabilization

摘要

The present application relates to a system for supporting a roof of a portion of a mine. The system includes a first plurality of stabilizing members disposed above the roof at a first elevation. The first plurality of stabilizing members originate from a first common location and terminate at a second elevation that is higher than the first elevation. The system further includes a second plurality of stabilizing members disposed above the roof and the first plurality of stabilizing members at a third elevation. The second plurality of stabilizing members originate from a second common location and terminate at a fourth elevation that is higher than the third elevation. The second plurality of stabilizing members are disposed generally perpendicular to the first plurality of stabilizing members.

主权项

1. A system for supporting a roof of a subterranean mine, the system comprising:
a first plurality of non-linear stabilizing members disposed underground above the roof of the subterranean mine at a first elevation, the first plurality of non-linear stabilizing members terminating at a second elevation, the first plurality of non-linear stabilizing members having tension applied thereto via a fastener plate assembly disposed only at a first end of the first plurality of non-linear stabilizing members; a second plurality of non-linear stabilizing members disposed above the roof of the subterranean mine and above the first plurality of non-linear stabilizing members at a third elevation, the second plurality of non-linear stabilizing members terminating at a fourth elevation, the second plurality of non-linear stabilizing members having tension applied thereto via a fastener plate assembly disposed only at a first end of the second plurality of non-linear stabilizing members; wherein, the first plurality of non-linear stabilizing members and the second plurality of non-linear stabilizing members are arranged to form a mesh; and wherein weight of the roof of the subterranean mine is distributed to a surrounding structure via the first plurality of stabilizing members and the second plurality of stabilizing members.
