Embodiment Construction
[0023] combine Figure 1-7 The shown coal mine safety and energy-saving ventilation system includes an exhaust duct 2 arranged on the inner top surface of the mine 1 and an air inlet duct 3 arranged on the ground inside the mine 1. The exhaust duct 2 is generally laid on a U-shaped The two ends of the U-shaped card 12 are anchored in the rock wall on the top surface of the mine 1; the air inlet pipe 3 is generally directly laid on the ground. The exhaust duct 2 is used to discharge the dirty air inside the mine, and the air inlet duct 3 is used to replenish fresh air in the mine 1. A number of air outlet louvers 4 are arranged on the air inlet duct 3, and the fresh air passes through the air outlet louvers. 4 fill in the mine 1.
[0024] The exhaust duct 2 of the present invention is uniformly provided with several exhaust sections 5, and the dirty air enters the main part of the exhaust duct 2 through the exhaust sections 5, and then is drawn out by the main part of the exha...

The invention relates to the technical field of mine ventilation, and aims to provide a coal mine safety and energy saving ventilation system capable of greatly reducing the safety risk. According tothe adopted technical scheme, the coal mine safety and energy saving ventilation system comprises an air exhaust pipeline arranged on the inner top face of a mine, and an air inlet pipeline arranged on the ground inside the mine, and the air inlet pipeline is provided with a plurality of air outlet shutter blades; the air exhaust pipeline is evenly provided with a plurality of air exhaust sections; and air exhaust shutter blades are arranged on the two sides of the air exhaust sections, the air exhaust sections on the inner sides of the air exhaust shutter blades are internally provided with vertical light thin plates parallel to the side walls of the air exhaust sections, the tops of the light thin plates are connected with the lower ends of sliding rods, the upper ends of the sliding rods penetrates through guiding holes in the top faces of the air exhaust sections and are connected with suspension air bags, and the suspension air bags are filled with gas concentration sensitive gas.According to the coal mine safety and energy saving ventilation system, traditional electric devices are abandoned, an air opening in a well is controlled purely mechanically, the risk of gas explosion can be reduced, and the coal mine safety and energy saving ventilation system has high safety and energy saving performance.
Description
technical field [0001] The invention relates to the technical field of mine ventilation, in particular to a coal mine safety and energy-saving ventilation system. Background technique [0002] In the process of coal mining, due to the mine construction environment, first of all, there is insufficient oxygen in the mine, which is not conducive to the long-term underground construction of the staff; secondly, gas will be continuously produced during the underground construction, and if it is not eliminated in time, it will inevitably affect the staff. In serious cases, it may even cause a gas explosion accident, threatening the life safety of the staff. Therefore, the underground pipeline ventilation system came into being. [0003] The existing ducted ventilation system mainly includes the air inlet duct and the exhaust duct laid in the mine. Several air inlets and exhaust outlets are arranged on the air inlet duct and the exhaust duct, and electric control dampers are arran...
