To improve the dust pollution problem in tunnel boring processes, we used numerical
simulation and on-site measurement. First, airflow and dust transport law under initial …

The increasing level of mechanization in coal mining means more dust and gas are
generated during excavation operations in tunnels. The high concentrations of dust and gas …

Coal mines produce large quantities of dust during production and transportation of coal,
especially respirable particulate matter of diameter< 10 µm (PM 10). This not only …

Dust pollution generated during the working process of a screening workshop in a coal
washing plant seriously threatens the occupational health of workers. To improve the …

This study, based on the construction of a wind flow-dust two-phase coupled diffusion
model, develops a novel method using a prepositioned air distributor to create an air curtain …

The external flow field of roadheader in Daliuta Coal Mine is numerically simulated, and
breathing process of drivers is experimented in this paper. The airflow field of the whole …

Nowadays, dust exposure pollution is receiving a lot of attention due to its significant impact
on public health. To investigate the impact of dust particle size and human respiratory …

The increase in highly mechanized coal mining has not only improved production efficiency
but also brought serious dust pollution problems. Currently, spraying is the most commonly …
