Benefits of technology

The invention has safety features and improves the structural integrity of ventilation stopping panels.

Problems solved by technology

Consistently however each combination of sheet metal components possess edges that upon expanding the panel create a hazardous cutting or slicing effect.
Moreover, the unreinforced edges are susceptible to damage during transient obviating the expansive capability of each panel.
Especially in mines with large airflows as the panels can break, bend and / or fail.

Abstract

The invention includes one or more ventilation stopping panels and more particularly to expandable ventilation panel used in the construction of a mine stopping.

Description

RELATED APPLICATIONS:[0001]This application claims priority to and benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 63 / 069,982 filed Aug. 25, 2020, which is also fully incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention generally relates to a ventilation stopping panels and more particularly to expandable ventilation panel used in the construction of a mine stopping.Discussion of the Related Art[0003]Mine stopping panels are used to control the flow of air through mine passages. These panels generally comprise first and second sheet metal panel members having a telescoping sliding fit one inside the other. The panel members are extended into a sealing engagement with the floor and roof of a mine passage.[0004]The panels come in a variety of configurations and designs. Consistently however each combination of sheet metal components possess edges that upon expanding the panel create a hazardous cuttin...
