A top-coal caving automatic control system with self-adaptive correction of coal caving time

Abstract

The invention discloses a top coal caving automatic control system capable of achieving self-adaption correction of the coal caving time. The top coal caving automatic control system includes a core controller, network servers, a control bus, and local controllers; the core controller can exchange data with the local controllers through the control bus and the network servers; the local controllers can achieve lifting and falling of a hydraulic support tail beam and stretching and contracting of a hydraulic support coal caving inserting plate through control of opening and closing of a hydraulic system electromagnetic valve, and can achieve automatic coal caving. Automatic coal caving can be achieved through the electro-hydraulic control technique and working face coal caving worker inspection; coal caving operations of coal caving workers are changed into coal caving inspection, the working load is reduced, the number of the working surface coal caving workers can be greatly reduced;the coal caving time is automatically controlled by the system, and the resource recovery rate is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to an automatic control system for caving top coal with self-adaptive correction of coal caving time. Background technique [0002] At present, the coal caving work at the fully mechanized top coal caving face of domestic coal mines is mainly carried out manually, which requires a large number of personnel, and the work intensity of the workers is relatively high. The working environment is harsh, and there are relatively large safety risks; the resource recovery rate is low. Someone has researched the fully mechanized top coal caving automatic control system based on ray-based coal rock identification technology, but due to the large investment and low identification level, it is not widely used in actual production. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide...
