Coal Mine Safety Management Method in Gradient

The effective management method is an important mean for safety. Based on the evolution process of hazard, hidden danger, event and accident, this article proposes a comprehensive set of coal mine safety management method in gradient. This method uses prevention control, deviation control and emergency control in the condition of the accident evolution segmentation, as well as takes time, development object and management means as different gradients. On the basis of management style, preventing dangerous source and correcting the defects and eliminating defects to timely emergency under hazardous conditions, this method makes the coal mine management more clear and the control of the accident more safety.
