operation of mining machines; applicable in remote control form remote control desk of continuous miners. SUBSTANCE: device has control desk with unit of direct control connected by communication lines with actuating station located on continuous miner and having spark-proof power supply unit and unit of electrohydraulic distributors. Each electrohydraulic distributor is connected via respective buttons of unit of direct control and communication lines to spark-proof power supply unit. Control desk has program block, indication block, matching amplifiers, relay with make contacts and block of program control buttons having button for sending commands to continuous miner, button for change over to next command, button for selection of direction of command execution and button for selection of required sequence of commands. Input of block of program control button is connected to spark-proof power supply unit. The first output of block of program control buttons is connected to relay make contacts whose outputs are connected to break contacts of buttons of directed control block. The second, third and fourth outputs of block of program control buttons are connected to the first, second and third inputs of program block, respectively. The first and second outputs of program block are connected with the first input of indication block and with inputs of matching amplifiers whose outputs are connected to relay windings and to the second input of indication block. Input of block of program control buttons is input of button for sending commands to continuous miner, and button output is the first output of block of program control buttons. The second, third and fourth outputs of block of program control buttons are, respectively, output of button of change over to next command, output of button of selection of direction of command execution, and outputs of buttons of selection of required sequence of commands. Program block may contain coder, two pulse shapers, register, binary counter, permanent memory and NOR-circuit. Input of block of program control buttons may be additionally provided with voltage converter through which program block of control desk is connected with spark-proof power supply unit of actuating station of continuous miner. EFFECT: increased labor productivity of operator and accurate execution of commands and control in semi-automatic conditions. 3 cl, 1 dwg
