Abstract An air curtain dust control technology for a fully mechanized mining face was developed, using a method that combined numerical simulations with field measurements in this paper. The results show that a triangular air curtain was formed between the shearer and the footway by the high velocity airflow field generated at the outlets of two fans after the technology was applied, which can effectively prevent dust from entering the driver's working area. Before the dust control technology was applied, the dust concentration of the shearer driver's working area exceeded 2000 mg/m3. However, after the dust control technology was applied, the dust concentration of the shearer driver's working area was reduced to 300 mg/m3. After verification through field measurements, the dust control rate of each measuring point, apart from the advancing support, exceeded 40%, and that of the shearer driver's working area was over 90%.

综采工作面除尘风机风幕除尘技术研究

摘要 本文采用数值模拟与现场实测相结合的方法，开发了一种综采工作面风幕粉尘控制技术。结果表明，应用该技术后，两台风机出口处产生的高速气流场在采煤机与人行道之间形成三角形风幕，可有效防止粉尘进入司机工作区。在应用粉尘控制技术之前，采煤机司机工作区的粉尘浓度超过2000 mg/m3。但应用粉尘治理技术后，采煤机司机工作区粉尘浓度降至300 mg/m3。经现场测量验证，各测点粉尘控制率，
