Embodiment Construction

[0012] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] Such as figure 1 As shown, the embodiment of the present invention provides a ventilation system for coal mines, including a vertical exhaust pipe branch 3 and a total exhaust pipe 4, the total exhaust pipe 4 is installed on the top of the coal mine main roadway 11, so The main exhaust pipe 4 is connected with the discharge chimney, and the branch roadway 3 of the exhaust pipe is installed on the top of the branch roadway on both sides of the coal mine stope 2, and the branch road of the exhaust pipe 3 is collected into the main exhaust pipe 4, so that A gas sensor 5 is arranged in the exhaust pipe branch 3, and a dustproof cover 6 is ar...

Abstract

The invention discloses a ventilation system for use in a coal mine. The ventilation frequency of air in the coal mine can be controlled and adjusted through an exhaust fan, a first fan and a blocking sheet; the content of harmful gas in the air in the coal mine can be detected through a gas sensor; once the detected content exceeds a set value, an alarm sends out alarm sound to remind workers of immediately evacuating or taking protection measures; the temperature of the air in the coal mine can be detected through a temperature sensor; the temperature sensor sends a signal to a controller when the temperature is high, so the controller controls to turn on the fan to reduce the temperature in the coal mine so as to provide a relatively comfortable working environment for the workers; meanwhile, both the gas sensor and the temperature sensor are used for wirelessly transmitting detected values to mobile terminals used by the workers, so real-time monitoring is realized.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a coal mine ventilation system. Background technique [0002] Mine ventilation is to continuously send fresh air from the ground to various underground locations (such as mining face), the purpose of which is to dilute and remove harmful gases and mine dust, provide the oxygen needed by underground personnel, and create a good environment at the same time. Climatic conditions. Mine ventilation is one of the most important technical means to ensure mine safety. The "Coal Mine Safety Regulations" stipulates that mechanical ventilation must be used in mines; two main ventilators of the same type must be equipped, one for operation and one for standby; mines must have a complete and independent ventilation system, and mine output must be verified according to the actual air volume, that is, "Determine production by wind". [0003] Whether the mine ventilation system is re...
