The study on optimized arrangement of microsemeism monitoring system and its application in 11th mine of Pingdingshan coal mining company
Abstract：According to mining scheduling of diphead panel of J2 in 11th Mine of Pingdingshan,technology of rockburst time and site prediction were presented;Key control area of rockburst was determined.Monitoring system of rockburst was optimized.14 underground stations and 2 ground stations were installed.Characters of frequency spectrum and energy were analysed according to rockburst records.The results revealed that the shock close to rockburst site was wider and larger energy;Shocks with low energy can loose energy;Silent period of roacburst energy would happen before strong rockburst.Therefore prevention system of strong rockburst was established,and control measures were proposed.
