Abstract

An intelligent coal mine fully mechanized coal mining face spray and aspirating control system disclosed by the present invention is composed of a positioning monitoring controller, a plurality of node spray and aspirating controllers, an infrared emission sensor, an explosion-proof electric ball valve, a spray nozzle and an overground monitoring terminal. The positioning monitoring controller and the spray and aspirating controllers finish the data exchange of the control signals and the working states in a wireless communication manner, and the working states of the spray and aspirating controllers are transmitted to the overground monitoring terminal to display real-timey. The spray nozzle is connected with the explosion-proof electric ball valve, and the explosion-proof electric ball valve is connected with the spray and aspirating controllers via cables. The infrared emission sensor transmits the signals to the node spray and aspirating controllers, and via the monitoring terminal, the on-off of the explosion-proof electric ball valve and the working state of the spray nozzle are controlled. By the control system of the present invention, the coal mining position of a coal cutter can be monitored real-timely, the spray area is large, the efficiency is high, and the dust concentration can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of dust control in coal mines, in particular to an intelligent coal mine fully mechanized mining face spray dust control system. Background technique [0002] Coal dust hazard is one of the unavoidable hazards in coal mine production. In the process of coal mining, a large amount of dust will be generated in various links such as ore crushing, transportation and screening. On the one hand, the working environment polluted by dust seriously endangers the health of workers. Long-term inhalation of dust can cause lung disease and pneumoconiosis; on the other hand, excessive dust concentration affects the safety performance of coal mining machinery. It is one of the main causes of coal mine dust explosion. With the continuous improvement of the comprehensive mechanization of coal mining face and the continuous application of high-power equipment, the dust and gas generated during the mining process have also in...
