Six Mine in Pingdingshan City in Pingdingshan, for one new mine under Pingdingshan Group. Mine is relatively simple geological conditions, the second a coal seam mining stability, seam dip angle of about 15 °, the average coal seam thickness of 4.05m. Mine design and production capacity of 0.6Mt / a, the service life of 35 years. According to the actual situation of the mine field to determine the way the mine shaft to develop a single level of development, mining area-type preparation, longwall mining method, mechanized mining technology, coal mine work system for the three classes, class preparation. Mining the development of environmental protection of mine has important implications, with the actual situation of the mine to take effective measures to protect the environment.
