Levels of exposure were estimated for the following operations: milling, mixing, machine line, sawing, and grinding. Asbestos concentrations ranged from 1.5–6.3 f/mL in 1956, to 0.3–5.0 f/mL in 1969, and to 0.9–1.7 f/mL in 1975. In all three time periods, the highest concentrations were observed in the milling and grinding operations.

Liaoning itself has reduced its own coal production, closing 259 coal mines since 2016 as part of China's "supply-side reform," which aimed to remove excess capacity. Huludao had dozens of coal mines in 2016. But nearly all of them, representing 810 million tons of annual production, have since closed.

Grinding effect on UBC. Coal from coalfeeders is fed to mills. Coal mills at power plants are being used to grind coals within a size range of several centimeters to very fine particles of 50–100 μm . Operational parameters are stable and have constant effect on UBC. Lack of grinding could be the main reason for the change of UBC content.

The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.

A change in which one or more new substances are formed is known as chemical change. For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide; a new substance formed out of the reaction. The colour of the surface of the iron also changes. Hence, rusting of iron is a chemical change.
