Mine downhole dust monitoring and control system

Abstract

The invention discloses a mine downhole dust monitoring and control system, and relates to the technical field of intelligent monitoring. A dust monitoring module is used for monitoring the downhole dust concentration in real time, and transmitting specific data of the downhole dust concentration to a switchboard; a dust eliminating module is mounted in the downhole and used for decreasing downhole dust concentration values; the dust monitoring module comprises dust concentration sensors, position sensors and a single chip microcomputer; the dust concentration sensors and the position sensorsare distributed at multiple downhole monitoring points and used for detecting the dust concentration on line and determining the specific positions of the dust concentration values at all the monitoring points correspondingly; and the output ends of the dust concentration sensors and the position sensors are both connected to the input end of the single chip microcomputer. On-line and real-time detection and control of the mine dust concentration can be achieved, the current situations that dust influences downhole operation in coal mine downhole operation places, improper mist spray is caused, consequently, coal is lost along with water, and water resources are wasted are avoided, and safe production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to an underground dust monitoring and control system in mines. Background technique [0002] A large amount of dust will be generated in various processes in the mine mining process. Workers working in this environment will inevitably inhale a large amount of dust and cause pneumoconiosis. According to coal mine statistics, the average annual death from pneumoconiosis is twice as high as the number of underground workers in the same period. Left and right; In addition, the dust is explosive and seriously threatens the safety of the mine. To this end, effective measures must be taken to control the diffusion and flying of dust, so that the dust concentration in the air flow of the roadway can be reduced below the safe value, so as to ensure the sanitary conditions of the underground working environment, protect the health of workers, and promote mine safety production....

AI Technical Summary

Problems solved by technology

[0003] At present, coal mines at home and abroad generally adopt the method of wet spray dust reduction to control the dust concentration. However, due to the lack of scientific detection and automatic control, there is blindness in practical application. Spraying causes coal to run off with water and wastes water resources
