Coal mine analysis system and method

Abstract

The invention provides a coal mine analysis system and method and relates to the technical field of coal mine analysis. The coal mine analysis system comprises an X-ray tube, a filter, a conveying mechanism, a ray detector, a multichannel analyzer and a main control unit, wherein the filter, the conveying mechanism and the ray detector are arranged in the optical path direction of the X-ray tube sequentially; the ray detector, the multichannel analyzer and the main control unit are electrically connected in sequence; the filter is used for filtering X-rays emitted by the X-ray tube, so that the filtered X-rays can enter a coal mine on the conveying mechanism, and excited rays are produced; the ray detector is used for detecting the excited rays; the multichannel analyzer is used for analyzing pulse amplitude of the detected excited rays; the main control unit is used for obtaining content of each component in the coal mine on the conveying mechanism according to the pulse amplitude. Online nondestructive analysis of the coal line can be realized conveniently with adoption of the coal mine analysis system and method, and the system in standby cannot produce harm to a human body or the environment.

Description

technical field [0001] The invention relates to the technical field of coal mine analysis, in particular to a coal mine analysis system and method. Background technique [0002] At present, most of the online non-destructive analysis in the coal mining industry is based on the isotope radioactive source (γ source) as the sample bombardment rays. Once the isotope source is manufactured, its radioactivity will always exist until its decay is exhausted. It is extremely harmful to human body and environment. Moreover, due to the strict supervision of radioactive sources by relevant national departments, there are very few companies with qualifications for the use, management, and storage of radioactive sources, and the requirements for external sales are very cumbersome. Harm is not easy to realize. Therefore, how to safely and conveniently realize the online non-destructive analysis of the coal mining industry is a major problem facing the coal mining industry at present. C...
