为了有效地控制煤矿井下粉尘，提出并开发了一种新型的泡沫防尘技术，简要阐述了泡沫防尘技术具有隔离性能好、接触面积大、润湿能力强、附着力强等优点，并介绍了该技术的具体内容，包括泡沫剂、泡沫发生器、和泡沫生产工艺。然后研究了发泡剂浓度与液体表面张力的关系，说明了泡沫发生器的原理。该技术在掘进工作面得到了应用。应用结果表明，该泡沫对煤矿井下粉尘治理效果显著。(C)2014由Elsevier B.V.代表中国矿业大学出版。
In order to effectively control the dust in the underground coal mine, this study proposes and develops a new technology for dust control by foam, and briefly demonstrates the advantage of the foam technology for dust control, such as the good isolation performance, large contact area, high wetting ability, strong adhesion and so on. Besides, the details of the technology are introduced, including the foam agent, foam generator, and foam production process. Then the paper studies the relationship between the foaming agent concentration and liquid surface tension, and explains the principle of the foam generator. The technology is applied in heading face. The application results show that the foam has a remarkable effect on dust control in underground coal mines.
