AI Technical Summary
Existing coal and rock identification technologies have low accuracy in harsh environments such as high dust, high humidity, and changing lighting underground. They are also susceptible to interference and pose safety hazards. In particular, gas and water mist affect the stability and safety of LIBS detection.
Design a coal and rock identification system, including a collection and drying chamber, a collection chamber, and a detection chamber. A suction mechanism is used to create a negative pressure state, and the air pressure difference drives the dust to form a stable particle flow. Combined with LIBS detection, the system ensures the safety and accuracy of the detection.
It enables real-time and accurate identification of coal and rock underground, reduces the risk of gas explosion, improves the stability and accuracy of detection, and is suitable for rapid detection in high-risk environments.
