为有效预防冲击地压事故的发生,唐口煤矿采用ARAMIS微震监测系统对工作面煤岩体内微震活动进行全时连续性监测。以5304沿空综采工作面为例,通过对微震事件的分布、频次、能量释放等方面的变化规律进行统计分析,分析结果对工作面矿压规律分析、控制和防冲设计具有较好的借鉴意义。
為有效預防遲擊地壓事故的髮生,唐口煤礦採用ARAMIS微震鑑測繫統對工作麵煤巖體內微震活動進行全時連續性鑑測。以5304沿空綜採工作麵為例,通過對微震事件的分佈、頻次、能量釋放等方麵的變化規律進行統計分析,分析結果對工作麵礦壓規律分析、控製和防遲設計具有較好的藉鑒意義。

To effectively prevent the happening of the impact ground pressure accident, tang mouth coal mine adopts ARAMIS microseismic monitoring system for working face of micro seismic activity in coal and rock full-time continuous monitoring. In 5304 fully mechanized coal face along, for example, based on the distribution of microseismic events, frequency and energy release the change rule of statistical analysis, the results of the analysis on the working face mine pressure regularity analysis, control and the design has good reference value.
