Abstract
A device for monitoring convergence between a first surface and a second surface, for example of a mine ceiling and floor, includes a measuring means having a plurality of measurements. The measuring means is attached to a support extending between and in contact with the first surface and the second surface. An indicator body and a release trigger are adapted for mounting in relation to the measuring means. The indicator body has one or more warning indicators for providing a visual display upon convergence between the first surface and the second surface. The one or more warning indicators are adapted for display in response to activation of the release trigger.

A device for monitoring convergence between a first surface and a second surface, the device including:
- a measuring means having a plurality of measurements;
- means to attach the measuring means to a support extending between and in contact with the first surface and the second surface;
- an indicator body adapted for mounting in relation to the measuring means;
- and
- a release trigger adapted for mounting in relation to the measuring means;
- wherein the indicator body includes one or more warning indicators for providing a visual display upon convergence between the first surface and the second surface;
- and wherein the one or more warning indicators are adapted for display in response to activation of the release trigger.
A method for monitoring convergence between a first surface and a second surface, the method including the steps:
- (i) attaching a measuring means having a plurality of measurements to a support suitable for extending between and in contact with the first surface and the second surface;
- (ii) installing the support so that it extends between and in contact with the first surface and the second surface;
- (iii) mounting an indicator body in relation to the measuring means, the indicator body having a release trigger and one or more warning indicators for providing a visual display upon convergence between the first surface and the second surface;
- and
- (iv) positioning the release trigger at a selected position in relation to the measuring means;
- whereby convergence between the first surface and the second surface is adapted to cause activation of the release trigger followed by display of the one or more warning indicators.
