Reference for suggestions on rationalization of underground coal mines (2)

Part 4 of the rationalization suggestions for underground coal mines

Our coal mine is located in Hancheng, xx Province. In order to reduce the noise in the underground tunnels (tunnels) of the coal mine, noise control of ventilation ducts and fans is required:

1. The underground tunnel (tunnel) of the coal mine is arch-shaped, 6m wide and 5m high, and the ambient temperature is normal temperature.

2. Fan: ?900mm, 2.65m long. The fan is a 55kw On the base, the base is 300mm higher than the ground. There is an anti-vibration pad under the fan. There is a soft connection between the fan mouth and the air duct. There are 4 fans, one on the ground. There are three fans in series in the middle of the air duct. It's along the direction of the air duct.

3. Air duct: 900mm, the material is 1.2mm galvanized plate, 1.1m/section, connected with 4*40 angle steel flange, the total length of the air duct is 2830m, due to the vibration of the air duct wall itself, the noise is emitted. To avoid noise, the entire ventilation duct runs along the ground level of the tunnel. There is a 300mm gap between the air duct and the tunnel wall. The air duct is 400mm high from the ground level. The air duct is fixed on a 2-meter pier with a flat iron.

IV. Noise test record, fan noise value is 102.5dB(A), duct airflow dynamic noise value 10m away from the fan is 98dB(A), 1/2 duct airflow between two fans The power noise value is 92.5 dB(A), and the comprehensive noise is about 93dB(A). Without affecting normal use, the noise is required to be reduced by 10-20 dB.
