Abstract
This device is used in the development of mineral and non-mineral ores for visual and distance registration of rock segregations on the ceiling and walls. Its construction ensures precision and accuracy of registered results. The device represents a signal bloc, which consists of a bearing plate (1), to whose upper part is fitted a cantering sleeve (2) with a nozzle in its top part; to the bottom part is coaxially-fitted a bottom bearing sleeve (3), with axes for a pressing (6) and hurling (7) spring in the direction of the bearing plate. Between the springs (6 and 7), a cassette (9) is positioned. It has an in-coiled signal band (8), whose one end is connected to the pressing spring. In the internal part of the bearing sleeve, to worked guiding channels (10), another spring (11) and a bordering with a heel fixating sleeve (12), are flexibly attached. On the external wall of the fixating sleeve is a measurement scale with apertures (13), in which are placed fixating needles (14). The signalling bloc is attached to a carrying element (16), located in an aperture (15), formed in the rock massif.
