Rock burst, a dynamic phenomenon in coal mine, is a special manifestation form of the rock pressure. In brief, rock burst is a kind phenomenon of catastrophic failures of the coal and rock mass. Without any obvious macroscopic premonitory symptoms, a large amount of energy is released when the rock burst occurs, thus causing enormous casualties and equipment damages. Since 2004, rock burst accidents have occurred many times in Junde Coal Mine, resulting in damages of mining roadways, suspension of mining activities, or worse still, abandonment of mining roadways and casualties. Over these years, Junde Coal Mine has formed a set of systematic methods and measures which have achieved good result in filed practice.
