Problems solved by technology
Due to the resistance effect of the dust removal net on the air flow, it will affect the reasonable matching of the air volume of each segment, resulting in the failure of the fan in the return fan station to start normally, which will eventually reduce the efficiency of the fan, and the ventilation and dust removal effect will be poor.

The invention discloses a ventilation and dust removal method of a slide breaking system, and relates to the technical field of underground mining. The slide breaking system comprises a pedestrian material well, an air return raise, an air inlet roadway, an air return roadway, a dust removal fan and an air return fan station, and further comprises a spraying device and a water curtain device, wherein the spraying device and the water curtain device are arranged in the air return roadway and are positioned between the air return fan station and the air return raise; the spraying device is arranged close to the air return fan station; the water curtain device is arranged close to the air return raise; and water mist and water curtain combined dust falling is carried out in the air flow direction according to the sequence of spraying firstly and then water curtain. Dust in the air return roadway is adsorbed and falls onto a bottom plate of the air return roadway under the combined actionof spraying, the water curtain and the wind power, and the effects of dust falling and polluted air purification are achieved. Polluted air generated by coarse breaking, ore loading and transporting through adhesive tapes and ore powder cleaning can be recycled after being purified, normal operation and stable air flow of fans of all sections can be guaranteed, the ventilation resistance of the coarse breaking and lifting system is not increased, the ventilation energy consumption is low, and the dust falling effect is good.
Description
technical field [0001] The invention relates to the technical field of underground mining, in particular to a method for ventilation and dust removal of a breakaway system. Background technique [0002] For mines using underground mining, in order to ensure the continuous safe production of mines, it is necessary to dig a series of tunnels from the surface to the ground to reach the ore body to form systems such as lifting, transportation, ventilation, power supply, air supply, water supply, drainage, and communication. The main task of ventilation is to send fresh air underground to provide the oxygen needed for breathing, discharge toxic and harmful gases and dust underground to the ground, and ensure that the air quality and dust concentration in the underground meet the standards. Therefore, the fresh air is required to meet the wind speed, temperature, and humidity specified in the underground. It is required to adjust the environment of the workplace, so as to protect ...
