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...

Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the scope of protection of the present invention is not limited to the following Described embodiment.

[0029] like Figure 1-3 As shown, the automatic coal mining method based on upper computer planning of the present invention includes a three-dimensional detection system for a working face, an accurate positioning system for a coal mining machine, an upper computer, and a coal mining machine that supports remote control functions (for example, developed by Tiandi Technology Shanghai Mining Equipment Co., Ltd. Co., Ltd. MG300 / 720-AWD3 type AC traction shearer); follow the steps below:

[0030] In the first step, the upper computer obtains the top and bottom of the...
