急斜特厚煤层动力学失稳现场声发射监测
Acoustic emission monitoring for dynamic destabilization of heavy and steep coal seam
摘要
Abstract
The movement regularity of heavy and steep coal seam disturbed mining zone is complex. Because of the formation of mining strata partial slip gravity stress, the influence caused by coal and rock stress concentration produces "strong" dynamic destabilization and destruction. Taking B3 +6 heavy and steep coal seam fully-mechanized sublevel caring mining in DAHONG coal mine as engineering background, the dynamic destabilization and destruction regularities of coal and rock are analyzed by acoustic emission monitoring for formulating scientific measures.关键词
