Abstract

The invention provides a top coal caving control method, system and device and electronic equipment, and relates to the technical field of automatic coal mining, and the method comprises the following steps: obtaining target top coal caving parameters; processing the target top coal caving parameters through a top coal caving control parameter prediction model, obtaining target control parameters of the target top coal caving support, wherein the target control parameters comprise the target opening and closing angle of the gate plate, the target telescopic distance of the gate plate and the target opening and closing time of the gate plate; and controlling the target top coal caving support to execute the current top coal caving operation based on the target control parameters. According to the method, the control parameters of the top coal caving support are predicted before top coal caving, then the top coal caving operation is completed through one-time opening and closing of the gate plate, the production efficiency is improved, the manual operation cost is reduced, and therefore the technical problems that in the prior art, a top coal caving method is low in production efficiency and high in cost are effectively solved.

Description

technical field [0001] The invention relates to the technical field of automatic coal mining, in particular to a top coal caving control method, system, device and electronic equipment. Background technique [0002] At present, the top coal caving is carried out by manually opening the gate in fully mechanized mining. The operator can indirectly judge whether the top coal caving is completed by visually observing the amount of gangue in the process of caving the top coal. When the amount of gangue in the caving process reaches a certain level, the gate is closed to stop caving Coal, complete a single ram top coal caving process. That is to say, in the prior art, it is necessary to manually intervene in the entire top-coal caving process. Due to the large dust in the top-coal caving process, it is impossible to observe the gangue-containing situation in real time, so the top-coal caving and parking must be carried out several times in the middle. Then observe the gangue cont...
