摘要： A hydraulic circuit for longwall support for use in underground mining for supporting a longwall by means of a plurality of support shields incorporates a pressure monitoring device in the pressure line between the load maintaining valve and the shield control valve. The pressure monitoring device can be a device for monitoring the piston position of the shield control valve which device signals a deviation of the set position predetermined by the shield control device from the measured actual position of the piston of the shield control valve in the form of a deviation signal. It may also be a pressure sensor which signals the deviation of the set pressure predetermined by the shield control device from the measured actual pressure in the form of a deviation signal. Signaling can be acoustic or optical.

摘要： A hydraulic control for a longwall support with a plurality of face support frameworks (1-3), which are adapted to be actuated in the sense of longwall support functions, in particular in the sense of the longwall support operations: robbing, advancing, and setting, comprises hydraulic control valves (8, 9) for each of the biasing elements, which are each arranged in close spatial relationship with the biasing elements, and subdivided into groups. Each group connects to a hydraulic pressure line (16), which extends over the longwall length of a plurality of face support frameworks, via a group connection line (18), which can be blocked by a group stop valve (20) as a function of the actuation of the control valves, specifically, when all control valves are not actuated and all biasing elements of the group are in a static state.

摘要： In a control system for the longwall support with a plurality of hydraulically actuated supports (mining shields), which are each automatically rearranged in the sense of robbing, advancing, and setting as a function of the position of the mining machine (coal cutter or plow), the position of the mining machine is automatically signaled to the mining shield control system. To this end, the mining machine is equipped with a position signaler. A microprocessor (31), which receives the signals of the position signaler, converts the signals into position signals and/or signals of the direction of movement. A radio set (32) transmits the position signals and/or signals of the direction of movement to radio receivers (33), which are distributed over the mining section and connected to the mining shield control system (34) for converting the position signals and/or signals of the direction of movement into signals for rearranging the mining shields (longwall support devices 1-18).

摘要： Apparatus for controlling the working stoke of the hydraulic props of a mine roof support unit is disclosed. The control apparatus comprises a control valve whose input side is connected to a hydraulic pressure line, and whose output side is connected to a working chamber of each of the props via a respective supply line. A sequence valve is provided in the supply line leading to one of the props. The sequence valve is such as to open the associated supply line when subjected to a predetermined hydraulic pressure, this predetermined hydraulic pressure being at least approximately equal to the hydraulic pressure necessary to overcome the resistance to the working stroke of another of the props. The sequence valve has a tubular valve body, a valve closure element mounted within the valve body, and a valve seat positioned within the valve body. A spring is provided for biassing the valve closure element towards the valve seat. A control piston carries the valve seat, the control piston having a piston face which, when subjected to hydraulic pressure in the biassing direction of the spring, is effective to displace the control piston so as to move the valve seat away from the valve closure element, thereby opening the sequence valve.
