摘要： The pressure measuring device has a housing in which a pressure chamber is located in a pin extending freely in the interior of the housing from a base. The pressure chamber wall is deformable elastically under an applied pressure. In the free end portion of the pin a magnetoresistive sensor is mounted which is moved with the chamber wall in a displacement occurring because of pressure changes in the chamber and thus is displaced relative to a permanent magnet. The magnet is mounted slightly transversely in the end portion of a compensating sleeve which surrounds the pin with wall contact. The change of the magnetic field at the sensor on displacement causes a proportional resistance change of the sensor so that an electrical signal proportional to the pressure change is generated which is a measure of the pressure. An amplifier for the signal from the magnetoresistive sensor can be mounted inside the housing adjacent the permanent magnet or the magnetoresistive sensor. Also advantageously the space between the housing and the compensating sleeve can be filled with insulation to further reduce temperature compensation requirements.

摘要： The advance of a mining front in longwall mining is effected by a process in which sensors measure the displacement of displacement cylinders coupling the linked prop elements to the linked conveyor elements with their respective cutters. A computer generates a baseline represented by the actual prop line as a starting point and the conveyor elements and cutters are then advanced all along the mining front via the displacement cylinders. The sensors input the respective displacements into the computer so that an actual conveyor line is determined in the computer and serves as the baseline for after-drawing of the prop elements via the cylinders. The new prop line calculated by the computer then forms the baseline for further advance and the advance can be controlled to ultimately align the conveyor elements along the conveyor line corresponding to a setpoint line defined by the computer and parallel to the original baseline.
摘要翻译：采矿前沿在长壁采矿中的进展是通过一个过程实现的，其中传感器测量位移缸的位移，该位移缸通过其相应的切割器将连接的支撑元件联接到连接的输送机元件。计算机生成由实际支柱线表示的基线作为起点，然后输送机元件和切割器通过位移圆柱体沿着采矿前端全部前进。传感器将相应的位移输入到计算机中，使得在计算机中确定实际的输送线，并且用作通过气缸抽取支柱元件的基线。由计算机计算出的新的支路线然后形成用于进一步前进的基线，并且可以控制进给以最终使输送机元件沿着与由计算机定义并与原始基线平行的设定线对应的输送线对准。

摘要： A hydraulic mine prop comprises a cylindrical top ram portion and a bottom ram portion which is telescopically engageable in said top ram portion and has an upper piston portion in sliding sealing engagement with the interior of said top ram portion. A ram head closes the top of said ram portion and a valve seat body is disposed between the ram head at a spaced location therefrom adjacent the top of the top ram portion and defines a vent space therebetween. The valve seat body also encloses a pressure space between itself and the piston and a passage is defined through the valve body within a valve seat portion thereof which communicates the pressure space to the vent space. The passage is closed by a spring-biased valve which may open against the biasing force of the spring. The construction includes one or more passages extending through the valve seat and through various generally radially extending passages defined in the body from the pressure space to the vent space and additional passages which are defined outwardly from the vent space to the atmosphere. The construction also includes a ring around the top ram portion having an annular passage which is communicatable through a port or bore of the top ram portion cylinder to a pressure holding valve space which is closable by a rotatable globe valve.

The working space is covered at the waste removal end by a shield which includes a lower portion pivotal on the floor skid, and an upper portion which is rigidly connected to the canopy at the opposite end of the canopy from the working face end. The shield is connectable to an extensible and retractable prop and a lemniscate guidance mechanism, so that the upper part of the shield may be moved upwardly and downwardly along its longitudinal axis. The upper part also carries an opening for the passage of a blast pipe which is supported on roller means carried by the canopy.

摘要： A mine prop provided with an overpressure valve of large flow-through section which opens when excessive forces suddenly act on the prop to discharge pressure fluid from the interior of the prop. The overpressure valve comprises a hollow cylindrical housing forming at one end a valve seat communicating with the fluid-filled inner space of the prop and a valve member axially guided in the housing for movement between a closed position engaging the valve seat and an open position. The fluid-filled space of the prop communicates with channels leading to the outside of the prop. The valve member is normally maintained in the closed position by a gas pillow under high pretension confined in a pressure space delimited peripherally by the wall of the valve housing and at opposite ends respectively by the valve member and a plug fluid tightly mounted in and closing the other end of the housing. The valve member and the plug are both formed from metal and are both provided at facing ends with annular slender sealing lips of triangular cross-section tapering toward each other, the outer surfaces of which are pressed into engagement with the inner peripheral surface of the housing by the pressure of the gas pillow.
