【摘要】：太平煤矿复采采煤工作面产尘大,在采取初次降尘除尘后,仍然达不到煤矿安全规定的矿井空气质量标准,针对该问题,研制了一种水幕除尘装置,安置在距工作面5 m处的回风巷道内,利用除尘液在水幕除尘装置中的纱网小孔上形成水膜的原理,吸附进入回风巷道内的工作面污风中的粉尘,达到对工作面二次降尘除尘的效果。结果表明,在回风巷道内安置水幕除尘装置对工作面再次降尘除尘,使得两次降尘除尘效果达到90%以上,很好地保证了回风巷道内设备和人员的安全,也极大地提高了矿井内空气质量。
[Abstract]:In Taiping Coal Mine, the dust production in the mining face is large, and after the first dust fall and dust removal, the coal mine air quality standard stipulated by the coal mine safety is still not reached. In order to solve this problem, a water curtain dust removal device is developed. Placed in the return air tunnel 5 m away from the working face, the dust from the working face in the return air tunnel is adsorbed by the principle of the water film forming on the small mesh hole in the water curtain dust removal device, and the dust in the dirty air of the working face entering the return air tunnel is absorbed. The effect of secondary dust reduction and dust removal is achieved. The results show that the water curtain dedusting device is installed in the return air roadway to reduce dust and dust again in the working face, which makes the effect of twice dedusting and dedusting more than 90%, which ensures the safety of the equipment and personnel in the return air roadway. It also greatly improved the air quality in the mine.
