首页 >> new technology to improve production in coal mines
Introduction In recent years, situation of safe production in coal mines of China is significantly improved, but it is still serious. From 2005 to 2009, 57,106 accidents occurred totally, among which 11,308 are accidents in coal mine, accounting for more than 20%. Number of serious accident of coal mine reaches to 176, as 4101 people died.
