Automatic coal drawing method for fully mechanized coal mining face of coal mine

Abstract

The invention discloses an automatic coal drawing method for a fully mechanized coal mining face of coal mine. The automatic coal drawing method comprises the steps that 1, a coal mining face host sets automatic coal drawing process parameters of all support controllers according to a preset automatic coal drawing process; 2, each support controller converts the coal drawing process parameters into an instruction set through a protocol and issues the instruction set to a control execution mechanism of the respective coal drawing support; 3, each control execution mechanism executes a coal drawing process flow for the first time, manually detects a coal rock demarcation point in the coal drawing process, and adjusts a tail beam dip angle value and the insertion plate withdrawing and stretching time of the corresponding coal drawing support; 4, an information detection module sends the received tail beam dip angle value and the insertion plate withdrawing and stretching time to a sample management module; 5, an information processing module compares a sample control parameter with a preset expected value, and updates the sample control parameter when the value of the sample control parameter is greater than the preset expected value; and 6, when a coal drawing action is executed again, a support control system executes the updated sample control parameter to carry out coal drawing operation.

Description

technical field [0001] The invention relates to the field of coal discharge in a fully mechanized coal mining face, in particular to an automatic coal discharge method in a fully mechanized coal mining face. Background technique [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 adopted for coal discharge, the current coal discharge timing and coal discharge cycle are determined by the experience of field 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 si...

[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
