Chongqing.The Mine is approximately 62 km southeast of Qijiang town center in Chongqing. It is 18 km
from the nearest railway station. The mining permit allows mining between elevations between 970m and
300m and covers a total area of 0.77km2.
There are 6 main Upper permian Longtan Formation coal seams in the district. The thicker M6 and M8 coal
seams were originally mined from 3 small mines. Those mines were amalgamated in 2007.
Production will continue in clean up mode above the 1,093m level adit while the new 1,023m level adit
is completed to access the deeper coal.
The M6 AD raw coal seam typical historical analysis is 2.24% moisture content, 33.24% ash, 10.20%
volatiles, 56.46% fixed carbon, 5.75% total sulfur, and 5,168 kcal/kg CV. The M8 AD raw coal seam typical
historical analysis is 2.28% moisture, 13.32% ash, 9.04% volatiles, 77.64% fixed carbon, 84% sulfur,
and 7,144 kcal/kg CV. Future production is expected to have similar quality.
