Coal rock detection technology and influencing factors Two major indicators of coal rock science manual test principle

Historical development and operation process of coal and rock detection

Coal rock micro-component content

The core of the measurement method is: “Distribution of various component contents”.

The accuracy of the measurement depends on the ability of the operator to identify the various components.

Mirror group reflectance

The core of the measurement method is: “the proportion of vitrinal groups with different reflectance values”.

The accuracy of the measurement depends on:

The ability of the operator to identify vitrinite components.

Stability of the instrument used

Control of the testing process.
