FIELD: mining.
SUBSTANCE: invention relates to mining. In particular, the proposed lava lining of underground mining workings with fasteners made in the form of shields, each of which has a shield control device, wherein the control panels are connected to a drift station, which is a lava control device, by means of a conductive bus with data lines for data transmission and conductors for power supply, and the conductors are connected to the power supply units located at a distance, with the fastening support in the area of excavation of the excavation machine, particularly of a milling machine or a cutting machine, are located along the lava closely to each other and form a corridor with a conveyor into which intrinsically safe cameras installed on mounting supports are directed with electronic light registration, wherein the cameras are connected to the drift station for data transmission. At the same time, along the lava at a distance from several mounting supports, respectively, one of the mounting supports of the observation area has a group of cameras, with two cameras each, preferably in one camera body per camera group with opposite optical orientation in the longitudinal direction of the corridor and the fullest coverage of the cross section of the corridor passage, both cameras of each group of cameras are equipped with intrinsically safe electronics, which contains a processor for data processing, a data collector and a radio device for high-frequency data transmission with an antenna for wirelessly connecting to a local network, each camera and camera group is assigned an address code, which is attached to the received data to identify the corresponding camera.
EFFECT: technical result is to provide an intrinsically safe chamber with electronics in the lava.
