Embodiment 1

[0035] Such as figure 1 figure 2 image 3 The shown intelligent top-coal caving control system includes data transmission and storage devices, and also includes:

[0036] Coal mining process discrimination system 1, including infrared transmitter 1-1, infrared receiver 1-3, coal mining machine operation identification device 1-2, infrared transmitter 1-1 and infrared receiver 1-3 are used to collect mining coal The motion and position information of the shearer 8 are input to the operation identification device 1-2 of the coal shearer for identification;

[0037] The roof pressure monitoring and forecasting system 2 includes a pressure sensor 2-1, a pressure data acquisition device 2-2, and a roof pressure monitoring and forecasting device 2-3, which are used to collect whether the working face is under pressure and the position of the pressure, and perform pressure forecasting;

[0038] The real-time evaluation system 3 for top-coal caving and caving includes a data colle...

Embodiment 2

[0043] Such as figure 1 figure 2 image 3 As shown, a coal discharging method of an intelligent top coal caving control system comprises the following steps:

[0044] 1) The coal mining process discrimination system 1 identifies the coal cutting process, coal cutting direction and position of the coal shearer 8 in the working face;

[0045] 2) The roof pressure monitoring and prediction system 2 determines whether the working face is under pressure and the position of the pressure;

[0046] 3) Top-coal caving real-time evaluation system 3 evaluates the top-coal caving performance of the working face;

[0047] 4) Coal discharge process decision-making system 4 receives the signal output from roof pressure monitoring and prediction system 2 and top coal caving real-time evaluation system 3 through intelligent coal discharge controller 4-3, and then performs logical operation through intelligent coal discharge controller 4-3 And send control instruction to tail beam 9, inser...

Abstract

The invention discloses an intelligent top coal caving control system and method. The system comprises a data transmission and storage device, a coal mining technology recognition system, a top plate pressure monitoring prediction system, a top coal caving real-time evaluation system, a coal caving technology decision system, an intelligent information feedback system, an intelligent coal caving deep learning system and a coal caving operation method by using the intelligent coal caving deep learning system; the intelligent top coal caving control system and method has the advantages that 1, it is not limited to coal caving operation, factors which are related to the coal caving operation are contained, the intelligent top coal caving control system corrects a coal caving module in the coal caving technology decision system continuously, and smooth implementation of the intelligent top coal caving control system and method is guaranteed; 2, few people even unmanned operation can be achieved, not only can the labor intensity of workers be reduced, but also the non-standard characteristic of manual operation can be avoided, the recovery rate of top coal is greatly improved, and coal resources are saved; 3, the system can be subjected to integration and docking with an existed electric-hydraulic control system, and the application cost of the system in an electric-hydraulic control working interface can be saved.

Description

technical field [0001] The invention relates to an intelligent top coal caving control system and method, belonging to the technical field of coal mine production. Background technique [0002] For the comprehensive mechanized top-coal caving face in coal mines, its operations mainly include coal mining and coal caving. With the promotion and application of electro-hydraulic control systems in coal mines, the degree of automation of underground coal mining operations is getting higher and higher. It can basically realize the operation with few people or even no one. However, for the coal caving operation, it still needs to be completed manually, which is inefficient and labor-intensive. Based on this, an intelligent top coal caving control system and method are needed for Realize the intelligent top-coal caving mining of the comprehensive mechanized top-coal caving face, and replace the characteristics of low efficiency, large randomness and non-standard coal caving by manua...
