Overview China’s introduction of 100 sets of fully mechanized mining equipment, from Japan, 8 sets, the proportion is larger. At present, Datong Mining Bureau of Jinhua Gong, Yungang, Yanzhou Mining Bureau of Nantun, Xinglong Zhuang and other four coal mines have six sets of equipment went down production. According to the statistics of 80 years, the yield per unit area in the working face is 49,618 tons / month, and the yield in 81 years is more than 40,000 tons. Each material consumption index is relatively low, the hydraulic support in the equipment is better, fault
