UNDERGROUND SYSTEM OF MONITORING, ANNUNCIATION AND DETERMINATION OF MINE WORKER LOCATION Russian patent published in 2010 - IPC E21F17/18 

FIELD: mining.

SUBSTANCE: system includes the following which is installed in mine working: sensors of monitoring mine environment background (temperature, gas content, methane, dust, displacement of beds, etc.), recording of location and direction of movement of mine workers, movable video and infrared cameras, device for detection and formation of control commands, terminals of operators performing the monitoring of mine environment background and location of mine workers and control of the system operation. Mine workers are provided with transponders and individual pendants. Transponders are intended to exchange code radio signals in request-reply mode with transmitting-receiving devices, which are located along mine working, which allows performing the monitoring of location and movement of mine workers. Individual pendants send individual light code signals in acoustic, infrared and radio ranges of waves; at that, sent codes are identified with personality of mine worker. Device for detection and formation of control commands, as well as database to it are implemented in computer. Database includes the data on mine working plan, location of sensors, coordinates of request-reply devices, individual codes of transponders and owners identified as per them, threshold parametres of emergency situations, modulation parametres of individual light code signals of pendants. Besides in mine working there arranged are movable video and infrared cameras by means of which the situation can be controlled, as well as devices for activation of individual pendants and detection of individual light code signals sent with pendants in acoustic, radio and infrared wave ranges. All sensors, transmitting-receiving devices, detection, activation devices of individual pendants, movable video and infrared cameras are connected to device of detection and formation of control commands.

EFFECT: monitoring of the well background, just-in-time warning of workers about threats, evacuation control, search of those who are suffering distress.
