To study the roof strata movement and coal pillar instability in multi-seam mining, a coal mine in Datong was taken as an example. Firstly, the bursting liability of coal and rock stratum was tested. The test results show that the 7#, 8#, and 11# coal seams in the mining area all have strong bursting liability.

mining property sits north of an extensive thrust fault system that roughly parallels the Mongolian border (Hendrix et al, 1996). The thrust front is evidence of a late Paleozoic intercontinental collision zone known as the Tian Shan suture and an element of the Tian ShanYin Shan suture (Heumann et al, - 2012).
Coal mining releases toxic materials into the soil and water. Bad mining can start coal fires which can burn for decades – releasing "fly ash" and smoke filled with greenhouse gases and toxic chemicals. It releases coal mine methane which is 20 times more powerful than carbon dioxide.

Coal combustion and CO x (CO 2 & CO) impacts on environment and health. Coal is an important source of energy around the world—approximately 41% of the world's electricity is generated from outdoor coal combustion (Nataly Echevarria Huaman and Xiu, Jun. 2014). However, indoor coal combustion is only used for domestic energy purposes.

Because the average coal mine lasted only ten years, little care was given to the appearance of these camps. Coal mining camp houses about 1900. Location unknown. One of the best remembered and most unusual coal camps was located in Monroe County in southern Iowa. Buxton, as it was called, was a thriving coal community during the early 1900s.
Huichao Yin, Bin Xu, Shangxian Yin, Wuzi Tian, Hui Yao, Haopeng Meng. Through field observation and theoretical study, we found that the Hanxing mining area has a typical ternary structure in coal mining under high water pressure of the aquifer. This ternary structure is the Ordovician limestone aquifer-aquiclude including thin limestones-coal ...
