Problems solved by technology

At the same time, the detection of coal-rock interface must meet the conditions of non-contact real-time detection, which further increases the difficulty of coal-rock identification. From the current point of view, the existing coal-rock detection technology is easily disturbed by various environmental factors. For complex mining It is not universal and timely under geological conditions, that is, there is no method that can perfectly solve the problem of coal rock identification

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Aiming at the present situation that the current coal-rock detection technology has low detection accuracy and is difficult to adapt to the working environment of a sudden change in fully mechanized mining face, the present invention provides an intelligent detection and recognition system and method for mine coal-rock interface.

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, the present...

Abstract

The invention discloses an intelligent detection and identification system and method for a coal-rock interface of a mine and relates to the technical field of coal-rock interface identification. Thesystem mainly comprises an intelligent lifting bracket fixed at the top of a coal mining machine, a non-contact radar antenna arranged at the top of the intelligent lifting bracket, and an operation terminal which performs information transmission with the radar antenna in a wireless mode. In the working state, the radiation direction of the radar antenna is perpendicular to the surface of a detected coal seam; and the operation terminal is used for acquiring radar data of the detected coal seam acquired by the radar antenna and drawing and displaying a coal seam position occurrence curve according to the radar data. Therefore, the detection precision can be improved; and the system and method can adapt to the abrupt change working environment of the fully mechanized coal mining face.

Description

technical field [0001] The invention relates to the technical field of coal-rock interface identification, in particular to an intelligent detection and identification system and method for mine coal-rock interface. Background technique [0002] The problem of intelligent detection and identification of mine coal-rock interface is a major problem restricting the intelligent mining of coal. Undercutting / overcutting of coal seams by shearers will lead to waste of resources, reduction of recovery rate, rock mixing to reduce coal quality, and cutting into rocks As a result of gear wear and explosions caused by sparks in high-gas areas, it is difficult to adjust the height of the drum by manual observation and empirical judgment to cope with sudden changes in working conditions. Efficient coal-rock intelligent detection and identification technology is the core technology that needs to be solved to realize intelligent coal-rock cutting. [0003] In reality, due to the influence ...
