A method of and system for monitoring roof load capacity index in mining headings.

摘要

3. A system for monitoring the load capacity index of a mining heading roof, consisting of measuring paths, an analysing system and a visualisation system, connected to the examined device. It is characterised in that it has two sets of pressure sensors (c1, ... cn) and two sets of displacement sensors (p1, ... pn), fixed to the structure of hydraulic props (2) of a mechanised mining cribbing (1) and functionally connected to a microchip recorder (3), powered from a spark arresting power feeder (4.)
