大冶金山店铁矿区地震监测与成因类型探析
|
摘要
收集、整理了大冶金山店铁矿区近几年微震活动的监测记录,并通过震中精定位和地震波形、频谱、震源机制解等综合性研究,认为该矿区的地震活动与矿山开采有密切关系,其成因类型属采矿诱发的地震活动,简称矿震。
On the basis of collection of field earthquake records in mining area and the neighboring regions,we carried out a series of comprehensive researches such as the accurate location of the epicenter,spectral analysis and focal mechanism solution.We concludes that there is a close correlation between earthquake in mining area and mining activities,and seismogenic pattern belongs to mining-induced earthquakes,or we can simply call them mine earthquakes.
