A coal mine mining dust prevention system and its application method

Abstract

The invention relates to the technical field of coal mine dust removal, in particular to a coal mine mining dust prevention system and its application method. The exhaust mechanism designed in the present invention is provided with an exhaust fan and a spare exhaust fan. When the dust concentration increases, the standby exhaust fan can be turned on to enhance the dust removal effect. The designed dust removal mechanism adopts the cylindrical surface of the first dust removal cover and the second dust removal cover as the dust removal surface, which increases the dust removal area and obtains better dust removal effect. At the same time, when the standby exhaust fan is turned on for dust removal, it can also ensure good dust removal effect. The designed elastic water pipe and the support pipe are slidingly connected, and the water curtain door can be moved without dismantling the water curtain door. The designed monitoring mechanism can monitor the dust concentration in real time. When the dust concentration is too high, it can send a signal to the control center to turn on the backup exhaust fan to enhance the dust removal effect. The monitoring mechanism is designed with a telescopic cylinder and a cleaning block, which can realize regular automatic cleaning of the lens and ensure the monitoring effect of the monitoring mechanism is accurate.

Description

technical field [0001] The invention relates to the technical field of coal mine dust removal, in particular to a coal mine mining dust prevention system and its application method. Background technique [0002] The working environment in the coal mine is harsh. The dust will not only affect the workers' sight, increase the failure rate of electrical equipment, but also cause serious damage to the health of the workers. When the comprehensive excavator is working, due to the complex excavation geology in the mine, a large amount of dust will be generated , although there are currently advanced foam dust removal technologies that can reduce the dust content, due to the complex working environment, the use of fans and water curtains can not only filter the dust in the air but also reduce the temperature in the mine and increase the frequency of ventilation.

[0002] The working environment in the coal mine is harsh. The dust will not only affect the workers' sight, increase the failure rate of electrical equipment, but also cause serious damage to the health of the workers. When the comprehensive excavator is working, due to the complex excavation geology in the mine, a large amount of dust will be generated , although there are currently advanced foam dust removal technologies that can reduce the dust content, due to the complex working environment, the use of fans and water curtains can not only filter the dust in the air but also reduce the temperature in the mine and increase the frequency of ventilation. Essential means of dust removal

However, the traditional fan and water curtain dust removal cannot flexibly adjust the dust removal intensity according to the actual working conditions, and the instrument for detecting dust concentration is easily polluted by dust, which reduces the detection accuracy
