Analysis on the impact crushing dust generation test method

  The method of impact crushing dust generation uses impact force to crush coal in a confined space. Although not simulating the process of coal crushing by tapered pick, it attributes coal crushing to a single variable, i.e. energy, avoids various external interference terms in the crushing process.

Characteristics of Dust in Coal Mines in Central North China and

The identification of the dust characteristics in coal mine working faces is essential for preventing coal dust explosion and occupational diseases. In this paper, dust samples from the coal mines in southern Shanxi province and Henan province, central North China, were selected as the research objects. The results show that the dust contains primarily

Characteristics of Dust in Coal Mines in Central North China and

Historical studies were conducted mainly by crushing coal in a laboratory to generate dust rather than collecting dust from the working face, (19−22) which was unrealistic because the chemical composition, particle size, wettability, and harmful elements of real dust are different depending on individual coal types or the surrounding rock.
