Coal rock automatic measurement and control technology is a "world technical problem" in the field of coal and rock

The key technical difficulties of coal rock analysis are as follows:

Fully automatic and accurate identification of coal and rock components:

This depends on imaging, mathematical algorithms and software solutions;

Real-time quasi-focus control during automatic scanning:

This needs to be achieved by means of optics, mathematical algorithms, computer software and electromechanical transmission;

Control of signal accuracy, linearity, stability and data conversion accuracy:

This needs to rely on the coordinated implementation of optics, electronic devices, software, etc.;

Solving it requires technical knowledge related to coal lithology, optics, imaging, mathematics, computer software, electronics, mechanical and electrical automation.

Early exploration:

The famous authoritative expert in the field of coal and rock in China, the founder of Applied Coal Petrology, Professor Shi Yong, in the late 1970s, invented the first photomultiplier tube type coal rock photometer in China, and has been working hard to explore A method of automating coal rock detection. However, due to factors such as the accuracy limitations of the electronics industry at the time, it did not end up with success, but it has gained some valuable experience.
