Abstract
A conveyor belt box check for installation in a mine is disclosed. The box check includes first and second generally parallel spaced-apart walls extending across a mine passage. Each of the walls has a conveyor belt aperture sized for receiving the conveyor. In some embodiments, access doors are provided in the first and second walls, and a partition extends between the first and second walls for separating the access doors from the conveyor belt apertures and for forming an air lock between the walls. A method of installing the box check is also disclosed.

A box check for a conveyor belt installed in a mine, the box check comprising first and second generally parallel spaced-apart walls extending across a mine passage, the first wall being closer to a mouth of the mine and the second wall being farther away from the mouth of the mine, each of the first and second walls comprising:
- a wall frame including horizontal roof and floor beams, and stopping panels secured to the wall frame for stopping open areas between the horizontal roof and floor beams;
- and
- a conveyor belt aperture frame assembly on the wall frame at least partially defining a conveyor belt aperture for receiving the conveyor belt.
A box check for a conveyor belt installed in a mine, the box check comprising
- first and second generally parallel spaced-apart walls extending across a mine passage,
- each for the first and second walls having a conveyor belt aperture sized for receiving the conveyor belt,
- access doors in the first and second walls, and
- a partition extending between the first and second walls for separating the access doors from the conveyor belt apertures and for forming an air lock between the walls.
A method of installing a box check for a conveyor belt in a mine passage, comprising
- installing first and second generally parallel spaced-apart walls to extend across a mine passage, characterized in that the installing comprises, for each of the first and second walls:
- telescopically adjusting horizontal roof and floor beams to fit a width of the mine passage;
- anchoring the roof and floor beams to a roof and floor of the mine passage, respectively;
- telescopically adjusting vertical beams to extend between the roof and floor beams to fit a height of the mine passage;
- bolting two of the vertical beams to the roof and floor beams at selected horizontally-spaced locations on opposite sides of a vertical centerline of the conveyor belt;
- and
- bolting horizontal frame members to the two vertical beams such that the frame members extend between the vertical beams at selected vertically-spaced locations to provide a conveyor belt aperture in the wall between the two vertical beams and between the horizontal frame members.
