Problems solved by technology

When the working face adopts the upward ventilation method, it is necessary to guide the air inlet flow in the mining area to the air inlet lane at the lower part of the mining area, and then enter the working face. The emitted heat is also added to the air flow, which is not conducive to cooling

Abstract

The invention discloses a ventilation method for a high-temperature mine mining area. The working surface of the mining area uses the manner of single-wing production layout; a wind inlet manner of track going uphill or going downhill and wind inlet through a gate way is used, and fresh wind flows enter the working surface through a wind inlet gate way; a wind returning manner of a belt transporting gate way and a transporting machine going uphill or going downhill for return wind is used, and coal mine methane passing through the working surface enters the transporting machine going uphill or going downhill in the mining area for return wind through the belt transporting gate way; a coal mining working surface uses the manner of downward ventilation, and the direction of wind flows is consistent with the direction of coal flows. The ventilation method is suitable for the ventilation of high-temperature heat-damage mine mining areas, and through the application of the method, favorable ventilation and cooling effects of the high-temperature mine mining areas are achieved.

Description

technical field [0001] The invention relates to a ventilation technology for mining areas in heat-damaged mines, in particular to a ventilation method for mining areas in high-temperature mines. Background technique [0002] The mining area ventilation system is the main component of the mine ventilation system and an important part of the mining area production system. The rationality of the ventilation system in the mining area not only affects the air volume distribution in the mining area, the air flow control in the event of an accident, and the smooth completion of production, but also affects the ventilation quality and safety of the entire mine. Due to factors such as the concentration of electromechanical equipment and personnel, and the high temperature of surrounding rock, the underground workplaces threatened by heat damage are mainly concentrated in the excavation and excavation working faces in the mining area. Therefore, a reasonable ventilation method in the...
