Abstract

The invention discloses a neutral network-based automatic coal drawing system for a fully mechanized coal mining face. The system comprises a system host (1), an electrohydraulic control system (2) and a plurality of hydraulic support pressure monitoring devices (3), wherein the system host (1) obtains external information through manual input or automatic transmission of the hydraulic support pressure monitoring devices (3), analyzes and processes the external information, processes and calculates the external information through a neutral network model to obtain a command signal, and transmits the command signal to the electrohydraulic control system (2); after the electrohydraulic control system (2) receives the command signal sent by the system host (1) or sent manually, the electrohydraulic control system (2) controls the opening and the closing of a coal drawing hole (44) of a fully mechanized coal mining face hydraulic support (4); the hydraulic support pressure monitoring devices (3) are used for monitoring the top coal pressure borne by the hydraulic support in real time and transmit monitoring data to the system host (1) in real time. The system can effectively solve the problem that automatic coal drawing is poor in adaptability to top coal thickness change and top coal and roof condition difference of the hydraulic support.

Description

technical field [0001] The invention relates to a fully mechanized coal mining face coal discharge system and method, in particular to a fully mechanized coal mining face automatic coal discharge system and method based on a neural network. Background technique [0002] The top-coal caving fully mechanized mining method has been widely used in the mining of thick and extra-thick coal seams. However, because the top-coal caving fully mechanized mining method has always used manual coal caving, it has obvious disadvantages: the timing of coal caving is completely controlled manually by experience, not only The efficiency is low, and the top coal is often unable to be fully released, resulting in a huge waste of coal resources; at the same time, casualties may also be caused by the roof falling, and a large amount of dust and gas generated during the coal discharge process also pose a serious threat to the health of the staff. threaten. [0003] Based on the above reasons, mor...
