The agent has the function of wetting and adsorbing the dust, so it plays the role of absorbing and soaking the dust into the aqueous solution, and finally plays the role of reducing the dust concentration in the air.
Description
技术领域 technical field
本发明属于煤矿开采领域，涉及一种能产生高倍、稳定泡沫的具有降低空气中煤尘及岩尘含量的表面活性剂。可用于煤矿井下采、掘工作面、运煤转载点、打眼作业等处的泡沫除尘。 The invention belongs to the field of coal mining, and relates to a surfactant capable of producing high-power and stable foam and reducing the content of coal dust and rock dust in the air. It can be used for foam dust removal in coal mine mining, excavation working face, coal transportation transfer point, drilling operation, etc.
背景技术 Background technique
煤矿粉尘是指在煤矿开拓、掘进、回采和提升运输等生产过程中产生，并能长时间悬浮于空气中的岩石和煤炭的细微颗粒。煤矿粉尘影响煤矿安全生产，威胁职工身体健康，是煤矿五大灾害之一。煤矿粉尘的危害性主要表现在4个方面，一是煤尘的自燃性和爆炸性，煤尘爆炸危险普遍存在，危害严重。二是严重的职业危害，据统计，目前仅煤炭行业尘肺病人数已超过20万，接近我国各行业肺患病人数的一半，而且每年还在增长，每年因尘肺死亡2500～3000人。三是降低了工作场所的能见度。在井下某些工作面煤尘浓度高，其能见度极低，往往导致误操作，增加工伤事故的发生。四是加速机械磨损矿尘对机械设备的影响。表现在加速机械的磨损，缩短精密仪器的寿命等。 Coal mine dust refers to the fine particles of rock and coal that are produced during the production process of coal mine development, excavation, mining, lifting and transportation, and can be suspended in the air for a long time. Coal mine dust affects the safe production of coal mines and threatens the health of workers. It is one of the five major disasters in coal mines. The hazards of coal mine dust are mainly manifested in four aspects. One is the spontaneous combustion and explosiveness of coal dust. The danger of coal dust explosion is ubiquitous and serious. The second is serious occupational hazards. According to statistics, the number of pneumoconiosis patients in the coal industry alone has exceeded 200,000, which is close to half of the number of lung diseases in various industries in my country, and it is still increasing every year. The third is to reduce the visibility of the workplace. In some underground working faces, the concentration of coal dust is high, and its visibility is extremely low, which often leads to misoperation and increases the occurrence of work-related accidents. The fourth is to accelerate the impact of mechanical wear and dust on mechanical equipment. It is manifested in accelerating mechanical wear and shortening the life of precision instruments.
目前我国煤矿主要采用的防尘措施有喷雾洒水除尘、通风除尘和除尘设备除尘等。喷雾洒水除尘用水量大、效果差、而且易造成工作面泥泞。通风除尘降尘效果差，尤其是对呼吸尘无明显效果。除尘设备除尘，受条件限制很多地点无法使用，除尘范围小。泡沫除尘属于化学降尘，具有结构简单、耗水量少、降尘率高尤其是对呼吸尘降尘效果好，是煤矿除尘的发展方向。 At present, the dust prevention measures mainly adopted in my country's coal mines include spraying water for dust removal, ventilation and dust removal, and dust removal equipment for dust removal. The water consumption of spraying and dust removal is large, the effect is poor, and it is easy to cause the working surface to be muddy. The effect of ventilation and dust removal is poor, especially for respiratory dust. Dust removal equipment can't be used in many places due to limited conditions, and the dust removal range is small. Foam dedusting belongs to chemical dedusting, which has simple structure, less water consumption, high dedusting rate, especially good dedusting effect on respiratory dust, and is the development direction of dedusting in coal mines.
