Embodiment Construction

[0028] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 , 2 , 3, the coal mine gas, gun smoke, and dust separation ventilation system of the present invention include a blower fan 2 and a discharge chimney, and are characterized in that the top of the coal mine main roadway 3 is provided with a main return air connected to the discharge chimney Passage 1, on the top of the branch roadway on both sides of each stope 8 of the coal mine, a branch return passage 4 connected with the main return air passage 1 is provided to form a multi-inlet and multi-return air system in the stope 8. The blower fan 2 is set at the connection between the return air channel 4 and the main return air channel 1,

[0030] The multi-inlet and multi-return system is a system composed of 2-5 air inlet channels and corresponding 2-5 return air channels. figure 1 , 2 , The embodiment show...

Abstract

The invention relates to the technical field of underground mine ventilation equipment, in particular to a mine gas, blasting fume and dust separation ventilation system. The system comprises fans and a blowdown stack; the top of a mine main roadway is provided with a main air return channel which is connected with the blowdown stack; the tops of branch roadways on two sides of each stope of a mine are provided with branch air return channels which are communicated with the main air return channel of the mine so as to form a double-air inlet double-air return system of the stope; the fans are arranged on the connection parts of the branch air return channels and the main air return channel; one end of each branch air return channel is connected with the fan, and the other end of each branch air return channel is provided with an air inlet; and each branch air return channel is provided with a ventilation control device which consists of exhaust openings formed in the sides of pipe bodies of the branch air return channel and valves matched with the exhaust openings. Different air flow of each section of the roadway and the requirement can be adjusted. The separation ventilation system is also suitable for ventilation of other underground mines.

Description

technical field [0001] The invention relates to the technical field of underground coal mine ventilation equipment, in particular to a ventilation system for separating coal mine gas, blast smoke and dust. This separate ventilation system is also suitable for other underground mine ventilation. Background technique [0002] Existing ventilation equipment in underground coal mines adopts mechanical forced ventilation equipment with the production roadway as the air inlet channel. The gas, gun smoke and dust generated at the front end of the roadway can only enter the main return air roadway after passing through the entire roadway and stope. The disadvantages of this type of mechanical forced ventilation are numerous: [0003] 1. It cannot fundamentally solve the hazards of gas, gun smoke and dust in the roadway. The reason is that the roadway gas containing gas, gun smoke, and dust all passes through a long ventilation roadway, and is finally discharged into the atmospher...
