Roof bolt bearing plate and method are disclosed for use in underground mining
operations. A dome-shaped roof bolt bearing plate and method support the roof in
a mine. The bearing plate is round or elliptical different from conventional commercial
roof support devices. No dangerous edges and corners protrude downward. A recessed
center is lower than the outer rim. A thin outer rim conforms to roof irregularities.
The roof bolt bearing plate and method have been found to provide important advantages
over conventional commercial roof support devices, including (1) concealing the
head of the roof bolt to a preferred degree, (2) conforming to the roof's irregularities
which will cause causing the plate to remain tight, (3) provide readability so
the installer can to determine the quality and integrity of installation and anchorage,
and (4) compressing the lower strata of the mine roof, thereby and creating a beam
like support for the upper layers of the mine roof.
