Abstract
A mine ventilation structure is disclosed. The structure comprises a deck including a plurality of elongate sheet metal panels. Each panel is generally of inverted channel shape in transverse cross-section, having a top web and first and second sides extending down from the top web. The panels are connected by tongue-and-groove connections between adjacent sides of adjacent panels. A mine ventilation deck panel of desired construction is also disclosed.
Claims24
A mine ventilation structure comprising
- a deck including a plurality of elongate sheet metal panels,
- each panel being generally of inverted channel shape in transverse cross-section, the panel having a top web and first and second sides extending down from the top web,
- the panels extending alongside one another and the top webs of the panels forming a deck surface,
- tongue-and-groove connections between adjacent sides of adjacent panels,
- each tongue-and-groove connection comprising a tongue formed in a first side of one panel received in a groove formed in a second side of an adjacent panel.
A mine ventilation deck panel, said deck panel being generally of inverted channel shape in transverse cross-section and comprising
- a top web,
- first and second sides extending down from the top web,
- a tongue on the first side for reception in a groove of a first adjacent deck panel alongside the first side, and
- a groove in the second side for receiving a tongue of a second adjacent deck panel alongside the second side.
A mine ventilation structure comprising
- a deck including a plurality of elongate sheet metal panels,
- each panel being generally of inverted channel shape in transverse cross-section, the panel having a top web, first and second sides extending down from the top web, and in-turned flanges at lower ends of the first and second sides of the panel,
- the panels extending alongside one another and the top webs of the panels forming a deck surface,
- tongue-and-groove connections between adjacent sides of adjacent panels,
- each tongue-and-groove connection comprising a tongue formed in a first side of one panel received in a groove formed in a second side of an adjacent panel,
- the tongue-and-groove connections being configured such that a portion of a vertical component of a vertical load placed on the deck is changed to a horizontal component for reducing stress resulting from the vertical load on the in-turned flanges of at least one of the panels.
