The invention provides a coal face support positioning system and method. An inter-frame positioning device comprises a base, a potentiometer and a positioning integrated circuit electrically connected with the potentiometer, two wire discs are hinged to the base and connected with the base through reset springs, and the potentiometer comprises a resistor body and a rotating body making contact with the resistor body. The resistor body is connected with the base in an assembled mode, the rotating body is connected with the wire discs in an assembled mode, and the rotating body and the wire discs are coaxially arranged. Measuring ropes are wound on the wire discs, the base is arranged on a hydraulic support, and the two measuring ropes are guided out from rope grooves in the same side of the base. The tail ends of the two measuring ropes are connected with the adjacent hydraulic support, an infrared distance measuring sensor is arranged on the position, at the end face of the work face,of the hydraulic support, and an infrared positioning end located on the same straight line with the infrared distance measuring sensor is arranged in a work face cross heading. The controller is insignal connection with the infrared distance measuring sensor and a plurality of positioning integrated circuits. The coal face support positioning system and method have the beneficial effects that all the supports of the coal face can be accurately positioned.
Description
technical field [0001] The invention relates to the technical field of underground positioning in coal mines, in particular to a support positioning system and method for a coal mining face. Background technique [0002] At present, the satellite positioning system cannot be used for underground positioning in coal mines. The existing downhole positioning system generally adopts base station positioning. Only when the signal generator to be tested enters the measurement range of the base station can the positioning be displayed, and generally it can only be located within the range, and the accuracy is low, so it cannot be precisely positioned. The positioning of the support on the working face generally needs to be accurate to 0.1m, and the existing base station positioning system cannot be used for accurate positioning of the support. In the process of output analysis, mine pressure analysis, etc., especially when studying the law of roof pressure, it is necessary to use ...
