How Do Microscopes Improve Our Lives Today? | Sciencing
Apr 25, 2018· Investigating With Microscopes. Environmental scientists examine soil and water samples, while geneticists observe chromosomes for defects. In engineering, material scientists use microscopes to inspect the components of structures such as buildings, bridges and dams to ensure that they are safe.

presented coal of the same rank (high volatile C). Investigation of the coal microstructure with a scanning electron microscope revealed substantial amounts of finely disseminated microcrystals of iron pyrites (11,12). Each coal sample was crushed to 4 cm top size and then was divided into three size fractions (4 cm χ 1 cm, 1 cm χ 48 mesh,

Evaluation of Outburst Potential at Sihe Coal Mine, China
Usually, the soft coal is formed by crushing coal seams into coal fines by thrusting, folding or sliding in coal seams millions of years ago. After the accident, the authors made an underground visit to the outburst site and made some observations. Onsite observation (Liu, et al., 2008) showed that coal seam close to the outburst site is
