Statistical Evaluation and Time Series Analysis of Microseismicity, Mining, and Rock Bursts in a Hard-Rock Mine.

Abstract The U.S. Bureau of Mines has long recognized the hazards associated with rock burst activity in underground mines. Concern over lost lives and injuries prompted the study to further characterize rock burst occurrence as related to microseismicity and mining. One hundred and one bursts over a period of 1,079 days of mining, where microseismicity rates and blasting were recorded, were used in the study. Statistical analyses investigated relationships between: (1) rock burst occurrence versus blasting; (2) rock burst size versus damage; (3) rock burst occurrence versus average microseismicity rates; and (4) rock burst occurrence versus local mine geometry.
