Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] In addition, an element in the present invention is said to be "fixed" or "disposed on" another element, and it may be directly on another element or an intervening element may also exist. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for pur...

Abstract

The invention discloses a coal-rock interface recognition system. The coal-rock interface recognition system comprises a detection module, a simulation test bench module, a visual image module and a data image module, and the detection module is used for recognizing a coal-rock mining interface on the basis of machine vision; the simulation test bench module comprises a physical simulation unit and a working face laboratory unit; the visual image module is used for extracting image information in a stratum medium; and the data image module comprises an analysis unit. According to the coal-rock interface recognition system, a coal-rock visual image information fuzzy set, a feature database and a rule base can be established, boundary conditions of high-resolution imaging of a complex geometrical shape heteroplasmon are determined, and coal-rock three-dimensional self-correlation back projection imaging is formed; and an image recovery unit is used for forming a surface layer visual detection three-dimensional geological distinguishing and pre-judging model of a coal face, texture features are constructed by using different scale decomposition coefficients, comparative analysis is carried out on coal-rock images, and high-precision recognition of a coal-rock interface is realized.

Description

technical field [0001] The invention relates to the technical field of information detection and collection, in particular to a coal-rock interface recognition system. Background technique [0002] Coal interface detection technology is one of the key technologies to realize the automation of coal shearer. When the shearer is working, the drum should cut along the boundary line of the coal and rock layers, otherwise the top coal will be left, or the drum will continuously cut the roof and floor rocks, which will cause the shearer to overload and malfunction, and even cause sparks to cause serious accidents on the working face. [0003] A reliable system has outstanding advantages in both economic benefits and safe operations. It increases the recovery rate of coal seams; reduces the content of gangue, ash and sulfur in coal; improves the efficiency of coal mining operations; reduces equipment wear; reduces equipment maintenance Reduces the amount and downtime; due to less v...
