The handbook is divided into five chapters. Chapter 1 discusses the health effects of exposure to respirable coal and silica dust. Chapter 2 discusses dust sampling instruments and sampling methods. Chapters 3, 4, and 5 focus on dust control technologies for longwall mining, continuous mining, and surface mining, by: To date, various physical and chemical dust control methods have been used in dust prediction and prevention, such as water spray, coal seam water infusion, foam and ventilation [8,9,10].However, as for these methods, there are advantages and disadvantages, for instance, a good water spray system has remarkable dust removal efficiency because it can decrease the Cited by: 4. With the development of modern coal mining equipment, high-yield, high efficiency, high-speed mining technology was achieved, but also a sharp increase in the amount of dust generated in the mine at the same time, it damage workers health and bring insecurity to mine production. This paper has summarized the existing domestic and international prevention and control Author: Shi Bin Wang, Ri Hui Chen, Xiang Yun Meng. Mining Dust Control & Suppression; Mining Dust Control & Suppression. There are many different sources of dust in mining operations. The following sections provide information and solutions for many of the more common dust sources in mining.

Coal dust can, if not handled carefully, result in serious health issues, chiefly high concentrations of breathable coal dust, which can lead to pneumoconiosis – or ‘black lung disease’ – and silicosis from mining material with a high quartz content. Water-only dust control systems have been used widely throughout the coal industry as a low-cost coal dust suppressant. At first glance, water seems like the natural solution to coal dust because it is safe and cheap. However, upon closer inspection, water is neither safe nor cheap. Water-only coal dust suppression systems use high volumes of.

Additional Physical Format: Online version: Anderson, Floyd Gustaf, Study of dust-control methods for continuous mining of coal. [Washington, D.C.] U.S. Dept. of. This handbook describes effective methods for the control of mineral dusts in mines and tunnels.

It assumes the reader is familiar with mining. The first chapter deals solely with dust control methods, regardless of the application. It is a brief tutori. A comparative study of dust control practices in Chinese and Australian longwall coal mines Article (PDF Available) in International Journal of Mining.

FIGURE F-1 Schematic of a room-and-pillar coal mine section. SOURCE: Arch Coal, Inc., FIGURE F-2 Details of the longwall face. SOURCE: EIA, There are several variations of each method.

However, ever since the introduction of continuous miners in the late s, room-and-pillar continuous mining has been gaining ground over conventional room-and-pillar mining. Consequently, current dust control practices fail to achieve optimal results which leads to dust control in underground mines being less than ideal.

Conclusions. This paper presents a comparison of statutory limits of dust concentration, dust monitoring methods and dust management practices between Chinese and Australian longwall coal by: In light of the ongoing severity of these lung diseases in coal mining, this handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust.

The current study reveals the exposure of coal mine workers to coal dust and the respiratory diseases diagnosed in these coal mine workers in Baluchistan and KPK provinces of Pakistan.

Most of the dust control models indicate the line-curtain air reaching the face is limited and does not extend. Lower air quantity at the face helps in containing and concentrating the dust close to the face where no occupations are present.

Hence, effective use of hydraulic sprays and directing the face dust-laden air into the scrubber may improve dust by: 4. The WEBA chutes are a very efficient alternative to other dust control methods and reduce dust levels to less than 95% of visible dust without the use of skirtboards, dust seals and extended covers.

Problems with dust, wear and impact can be greatly reduced or eliminated with a WEBA chute. Dust control vacuums for the mining industry. Such air movement also serves to remove dust generated by the coal handling from the working face.

The flow of air for these purposes can vary from 2, to 20, cfm per section depending Study of Dust-Control Methods For Continuous Mining of Coal.
