Load-Bearing Pressurized Liquid Column
US Patent:
6637159, Oct 28, 2003
Filed:
Nov 27, 2001
Appl. No.:
09/995964
Inventors:
Roland B. Heath - Vernal UT
Assignee:
Efficient Mining Systems LLC - Vernal UT
International Classification:
E21D 1500
US Classification:
52 221, 405289, 2483541, 254 93 R
Abstract:
A load-bearing, pressurized-fluid column apparatus and method for supporting a load or mine ceiling with respect to a support surface or mine floor includes an elongated, flexible sleeve retains a substantially incompressible liquid. The elongated, flexible sleeve has a collapsed and an expanded configuration. In the collapsed configuration, the sleeve is not filled, and has a first, shorter length. In the expanded configuration, the sleeve is filled with the liquid, and has a second, longer length sized to extend to and between the load and the support surface. A valve allows the liquid to be added and prevents escape of the liquid. A base can seal a lower end of the sleeve, and can be disposed on the support surface. A cap can seal an upper end of the sleeve, and can be capable of abutting the load.

Filed:
Oct 27, 2004
Appl. No.:
10/976360
Inventors:
Roland B. Heath - Vernal UT, US
Assignee:
Efficient Mining Systems LLC - Vernal UT
International Classification:
F16M 13/00
US Classification:
248631, 2483541, 2482001, 248636, 248562, 405288, 405289, 52 221
Abstract:
A load-bearing, pressurized-fluid column apparatus and method for supporting a load or mine ceiling with respect to a support surface or mine floor includes an elongated, flexible sleeve and bladder retain a substantially incompressible liquid. The sleeve and bladder have a collapsed and an expanded configuration. In the collapsed configuration, the sleeve and bladder are not filled, and have a first, shorter length. In the expanded configuration, the sleeve and bladder are filled with the liquid, and have a second, longer length sized to extend to and between the load and the support surface. A valve allows the liquid to be added and prevents escape of the liquid. A base can seal a lower end of the sleeve, and can be disposed on the support surface. A cap can seal an upper end of the sleeve, and can be capable of abutting the load.
