FIELD: mining.
SUBSTANCE: hybrid communication system for drilling installation includes telemeasuring system of drilling column and at least one hybrid telemeasuring system. Drilling column telemeasuring system is located in drilling column and connected to ground unit during the operation. Hybrid telemeasuring system is connected during the operation to telemeasuring system of drilling column and to downhole tool for signal transmission between them. At that, hybrid telemeasuring system includes upper connector, lower connector and cable. Upper connector is connected to telemeasuring system of drilling column. Lower connector is connected to downhole device. Cable connects upper and lower connectors.
EFFECT: higher reliability and data transmission rate.
