FIELD: mining.
SUBSTANCE: invention refers to the field of hydrogeology and engineering geology and may be used upon assessment of ground surface deformation. Device contains observation borehole, casing pipe, transmitter, converter, flexible cable, measuring pulley with profiled groove and deep-earth anchor installed in uncased section of observation borehole. At that transmitter is made in the form of converter. Measuring pulley is installed on two supports with option of free rotation. Flexible cable is arranged in profiled groove of measuring pulley in two turns and rigidly fixed by its one end on deep-earth anchor in borehole bottom and by the other end is connected to back-weight by means of measuring pulley. Axis of measuring pulley is rigidly connected to converter which is attached to third support and connected to converter for transmission of digital code to monitoring centre.
EFFECT: design simplification, improving of accuracy of soil subsidence determination, thus preventing oncoming accident.
