Automatic coal discharge method in fully mechanized mining face

Abstract

The invention discloses an automatic coal discharging method for fully mechanized mining working faces in coal mines. 1. The main machine of the coal mining working face sets the automatic coal discharging process parameters of each support controller according to the preset automatic coal discharging process; 2. Each support controller Transform the coal discharge process parameters into an instruction set through the protocol and send them to the control executive agencies of their respective coal discharge supports; 3. Each control executive agency executes the coal discharge process for the first time, manually detects the coal-rock boundary point in the coal discharge process, and The inclination value of the tail beam of the coal-loading support and the retraction and extension time of the inserting plate are adjusted. 4. The information detection module sends the received tail beam inclination value and the retraction and extension time of the inserting plate to the sample management module; step 5, information processing The module compares the sample control parameter with the preset expected value; when the sample control parameter value is greater than the preset expected value, it is updated to the sample control parameter; step 6, when the coal discharge action is performed again, the support control system executes the updated sample control parameter to perform Coal operation.

Description

technical field [0001] The invention relates to the field of coal caving in fully mechanized coal mine working face, in particular to an automatic coal caving method for fully mechanized coal mine working face. Background technique [0002] At present, the fully mechanized coal mining face is limited by the coal and rock identification technology during automatic coal drawing, and the coal and rock boundary point cannot be identified when the fully mechanized mining face is automatically drawn, resulting in insufficient coal drawing or more gangue. When manual coal caving is used in the coal caving work, the current coal caving timing and coal caving cycle are determined by the experience of the on-site operators. Therefore, the overall quality of the workers is relatively high. At the same time, the underground environment of coal mines is relatively harsh, the situation is more complicated, the operation of coal caving is cumbersome, the labor intensity is large, and the e...

[0002] At present, the fully mechanized mining face is limited by the coal-rock identification technology during automatic coal discharge, and the coal-rock boundary point cannot be identified during the automatic coal discharge of the fully mechanized mining face, resulting in insufficient coal discharge or more gangue

When manual coal discharge is used for coal discharge, the current coal discharge timing and coal discharge cycle are determined by the experience of the on-site operators. Therefore, the overall quality of workers is required to be high, and the coal production rate and mixed gangue rate of coal discharge are affected by the quality of workers. At the same time, the underground environment of the coal mine is relatively harsh, the situation is more complicated, the coal discharge operation is cumbersome, the manual labor intensity is relatively high, and the coal discharge efficiency is low
