Embodiment Construction

[0129] Such as figure 1 A method for identifying the coal-rock interface of an intelligent working face based on geological data is shown, including the following steps:

[0130] Step 1. Coal seam three-dimensional modeling based on geological data, the process is as follows:

[0131] Step 101. Acquisition of measured geological data: obtaining measured geological data of the coal seam 1 to be mined; the measured geological data of the coal seam 1 to be mined includes coal seam geological data, mining roadway geological data and eye-cut geological data;

[0132] The working face of the coal seam 1 to be mined is a recovery working face, and the transportation lane 2 of the working face and the return air lane 3 of the working face are connected through the cutout 4; the transportation lane 2 of the working face and the return air lane 3 of the working face are parallel and both of them are vertically arranged with the length direction of the mining face, and the cutout 4 is a...

Abstract

The invention discloses an intelligent working face coal-rock interface recognition method based on geological data. The method includes the first step of coal seam three-dimensional modeling based on geological data, the second step of coal seam primary mining and coal-rock interface recognition, and the third step of coal seam subsequent mining and coal-rock interface recognition. The first step includes the substeps that 101, geological data is obtained through actual measurement, wherein actual measurement geological data of to-be-mined coal seam is obtained and includes coal seam geological data, mining roadway geological data and cut hole geological data; 102, a coal seam model is constructed, wherein data storage, interpolation operation, three-dimensional coordinate database generation and model construction are conducted. The third step includes the substeps that the to-be-mined coal seam continues to be mined by means of a coal mining machine from back to front, and a coal-rock interface of the working face is recognized before each working face is mined. The method is simple in step, reasonable in design, convenient to implement and good in use effect, and the coal-rock interface is conveniently, quickly and accurately recognized according to the actual measurement geological data and cylinder height adjustment track prediction data.

Description

technical field [0001] The invention belongs to the technical field of coal seam mining, and in particular relates to an intelligent coal-rock interface identification method in a working face based on geological data. Background technique [0002] In recent years, coal mining enterprises have increased investment in research and development of science and technology, effectively promoting mines to move from digital mines to intelligent mines. Unattended coal mining has become the most prominent issue in the coal mining industry. The intelligent mining of coal mines by using intelligent working faces (also known as intelligent fully mechanized mining faces) is not only a problem faced by the country, but also a difficulty faced by the international community. Coal-rock interface recognition is one of the key issues in realizing an intelligent working face. Coal-rock interface recognition can enable the shearer to have the ability to automatically track the coal-rock interfa...
