Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] A method and device for identifying coal and rocks based on the difference in reflective properties of objects of the present invention is composed of a sensor (1), a sensor base (2), a signal processing center, and a feedback device. In the actual operation process, the sensor is located at a point on the edge of the drum. When the shearer completely cuts coal in the coal seam, the track identified by the sensor is all coal, that is, Figure II In (5), when the shearer has just cut the rock formation 3cm deep, the sensor will enter the rock formation for a period of time. During the operation of the shearer, the sensor identification track is Figure II In (4), when the sensor turns to the highest point, the recognized image is the rock formation (6). This period of time is very short, and the coal rock identification sensor can capture this small change for accurat...

Abstract

A coal rock identification device and method for an underground coal seam of a coal mine based on object reflection performance difference are suitable for automatic identification of a coal rock interface of a working face under fully mechanized mining working conditions. The recognition device comprises a front-end sensor, a signal processing center and a feedback device. The basic method comprises the following steps of: capturing the change by using a sensor according to the surface structure and color difference of the coal and the rock and the different reflecting capacities of the coal and the rock, transmitting a signal back to a processing center, and quickly distinguishing the coal and the rock through the identification processing of the signal processing center, so as to obtain the real-time boundary condition of the coal and the rock of the underground coal mine working face. Therefore, correction of the coal mining working route of the coal mining machine is realized. The device is simple in structure, high in measurement result accuracy and wide in practicability.

Description

technical field [0001] The invention relates to a coal-rock identification method based on differences in object reflective properties, which is suitable for automatic identification of coal-rock interfaces on working faces under mechanized working conditions of fully mechanized mining. Background technique [0002] With the advent of the 5G era, a new round of scientific and technological revolution kicked off. Automation, intelligence, and the Internet of Everything have become the direction of future technological development. The coal industry is the main energy supply in our country, so it is imperative to speed up the modernization of mines. The realization of unmanned mining is the technological development trend of safe, efficient and green coal mining in the future. Its key technologies mainly include automatic positioning, autonomous navigation, automatic deviation correction, and self-adaptive coal cutting with the shearer as the core. Among them, the coal-rock in...
