Coal-rock interface recognition handheld system

Abstract

The invention relates to a coal-rock interface recognition handheld system which comprises a coal-rock interface recognition processor and a handheld terminal, wherein the coal-rock interface recognition processor is arranged on a tail beam of a top coal caving hydraulic support or a rocker arm of a coal mining machine, and comprises a first shell, a sensor, a first circuit module, a first wireless module and a battery; and the handheld terminal comprises a second shell, a second circuit module, a man-machine interaction module, a second wireless module and a power module. The coal-rock interface recognition handheld system has the advantages that a method for distinguishing coal-rock recognition can be provided for a top coal caving working surface, the handheld terminal can be used for receiving the coal-rock recognition detection results sent by coal-rock interface recognition processors respectively arranged on a plurality of hydraulic supports at the same time, and a mode which relies on automatic coal release mainly while manual intervention subsidiarily can be realized on the top coal caving working surface provided with an electrohydraulic control system, so that the work load of operators can be further reduced, and the degree of automation of a fully mechanized caving face can be improved.

Description

technical field [0001] The invention relates to a hand-held system for coal-rock interface identification, which is mainly used in coal mine caving process control by a hydraulic support on a fully mechanized top coal caving face. Background technique [0002] Due to the complex coal seam occurrence conditions in different regions or different working faces in the same region, the coal seam identification technology has not been widely used in different geological conditions for fully mechanized caving working faces in coal mines. The process is mainly manual operation. The operator observes the coal discharge situation at the coal discharge port to decide whether to end the coal discharge process. However, due to the large coal dust and dust at the coal discharge port, it is difficult to see whether the coal or rock is being placed in the coal discharge port. Under normal circumstances, the operator relies on the sense of hearing to identify the coal discharge situation of ...

[0002] Due to the complex coal seam occurrence conditions in different regions or different working faces in the same region, the coal seam identification technology has not been widely used in different geological conditions for fully mechanized caving working faces in coal mines. The process is mainly manual operation. The operator observes the coal discharge situation at the coal discharge port to decide whether to end the coal discharge process. However, due to the large coal dust and dust at the coal discharge port, it is difficult to see whether the coal or rock is being placed in the coal discharge port. Under normal circumstances, the operator relies on the sense of hearing to identify the coal discharge situation of the coal discharge port. The operator must operate near the coal discharge port and complete it by experience, which makes the working environment of the underground workers poor, and the coal has a high gangue content. , cannot accurately and effectively control the coal quality, resulting in high coal ash content
