Description

Technical Field

[0001] This invention relates to the field of coal slime weighing, transfer monitoring and control technology in underground coal mines, and more specifically, to an Internet of Things-based coal slime weighing, transfer monitoring and control system for underground coal mines. Background Technology

[0002] Weighing and transferring coal slime underground is a crucial step in coal mine production. By analyzing the coal slime loss at each stage of the process, it is possible to ensure that the coal slime weight reaches the required weight for transfer. Monitoring and controlling the weighing and transferring process of coal slime underground can significantly improve production efficiency and reduce production costs. Therefore, the importance of monitoring and controlling the weighing and transferring process of coal slime underground is self-evident.

[0003] The existing monitoring and control methods for coal slime weighing and transfer in underground coal mines still have the following problems: 1. Only the coal slime loss in the entire process is analyzed, without analyzing the coal slime loss in each step of the coal slime weighing and transfer process in underground coal mines. This results in a large error in the coal slime loss assessment results for the entire process, making it impossible to accurately understand the coal slime loss situation. This reduces the accuracy of confirming the required weight of coal slime to be transferred in the current target process, and thus increases unnecessary resource waste.

[0004] 2. The display status of the weighing instrument was not analyzed, that is, the abnormal display status of the target weighing instrument was not analyzed, which made it impossible to guarantee the display accuracy of the weighing instrument. As a result, the final analysis results had defects such as low accuracy and poor rationality, which reduced the working reliability of the weighing instrument.

[0005] 3. The current target process did not analyze the condition of the coal slime and the feeding hopper. Specifically, the viscosity of the coal slime and the damage of the feeding hopper were not analyzed. Therefore, it was impossible to consider the factors that caused changes in the coal slime loss from multiple perspectives and dimensions, and thus it was impossible to provide effective data support for confirming the required weight of coal slime to be transferred in the feeding area during the current target process.
