Automatic coal mining method based on host computer planning

Abstract

The invention discloses an automated coal mining method based on upper computer planning. The method comprises the following steps: acquiring working face roof and floor conditions by an upper computer by virtue of a three-dimensional working face detection system; 2, acquiring coordinates of a coal cutter in a three-dimensional working face space by an accurate coal cutter positioning system so as to accurately position the current working profile; 3, generating current and next working face roof and floor changing curves according to the three-dimensional working face detection results and the working face profile; 4, planning curve correction and confirmation; 5, generating heights of upper and lower drums of the coal cutter and speed parameters of the coal cutter according to the planning curve; 6, remotely regulating the heights of upper and lower drums of the coal cutter and the speed of the coal cutter by a remote control interface; 7, executing a detection instruction, performing dynamic regulation on the next instruction according to the execution results, and realizing closed-loop control. The automated coal mining method disclosed by the invention has the advantages thatthe planning curve is modified by an operator in a graphical mode, the modified effect immediately presents on a display interface, and visualization of the whole automation process is realized.

Description

technical field [0001] The invention relates to an automatic coal mining method in a coal mine, in particular to an automatic coal mining method based on upper computer planning. Background technique [0002] Coal mining has gone through several stages of blast mining, general mining, and fully mechanized mining. It is currently in the stage of automatic mining and is moving towards the stage of intelligent mining. In the process of automated mining, the automation of the shearer is the core of the entire control technology. It can be said that the level of automation of the shearer represents the overall level of automated mining. [0003] At present, in the automatic coal mining face, the automatic coal mining of the shearer is basically based on memory cutting, and the memory cutting is divided into two steps: Step 1: Manually operate the shearer to demonstrate the knife, and the shearer records The cutting parameters in the process of demonstrating the knife is called t...

AI Technical Summary

Problems solved by technology

[0004] From the implementation principle of memory cutting, it can be seen that the cutting parameters of the shearer in the memory cutting process are determined by the demonstration knife. , the change of the bottom plate

In fact, memory cutting is based on the assumption that the conditions of the top and bottom of the working face remain unchanged or change little. The adaptability of memory cutting will become poor, requiring frequent manual demonstration knife, or it cannot be used at all
