Abstract
A liner plate structure, system and method is provided for lining of mine shaft bores, tunnels and the like. The liner plate structure includes a primary plate portion and at least one flange disposed at a side edge of the primary plate portion. A polymer seal element extends along a recess within an exterior surface of the flange.
Claims26
A liner plate structure for use in lining shafts and tunnels, the liner plate structure comprising:
- a primary plate portion;
- at least one flange disposed at a side edge of the primary plate portion, a recess extending along the exterior surface of the flange and holds a seal element that is bonded to at least a bottom surface of the recess, the seal member applied via a plural component processing technique.
A liner plate structure for use in lining shafts and tunnels, comprising:
- a primary plate portion having a length and height, the length greater than the height, the primary plate portion further including first, second, third and fourth side edges;
- first, second, third and fourth flanges respectively disposed at the first, second, third and fourth side edges, each flange having a plurality openings therein for facilitating connection to another liner plate structure, each flange includes a respective recess that is aligned with the recess of adjacent flanges to produce a continuous recess that circumscribes the liner plate structure;
- a continuous, seamless seal structure extending along the continuous recess and formed by a polymeric material, where the seal structure is bonded to at least a portion of the recess.
A method of forming a plate structure for use in lining shafts and tunnels, comprising:
- utilizing a liner plate structure with a primary plate having first, second, third and fourth flanges respectively disposed at first, second, third and fourth side edges of the primary plate, each flange including a respective recess that is aligned with the recess of adjacent flanges to produce a continuous recess that circumscribes the line plate structure;
- applying a seal member to the continuous recess utilizing a plural component material processing technique and in a manner such that the seal member is bonded to a portion of the recess and includes an upper portion protruding from the recess.
