摘要
按照煤岩的冲击倾向性指标，对天池煤矿１号井１８采区的煤岩进行了单轴（σ１＞σ２＝σ３＝０）和三轴（σ＞σ２＝σ３＝６ＭＰａ）冲击倾向性试验研究，结果表明，天池煤矿煤层具有中等冲击倾向性，而顶、底板岩石具有强烈冲击倾向性。
Experiments were conducted to research the uniaxial(σ 1〉σ 2=σ 3=0)and triaxial(σ〉σ 2=σ 3=6MPa)bump proneness of coal and rock in 18th working district of No.l shaft in Tianchi Coal Mine acccording to the index of bump proneness of coal and rock.The reults showed that moderate bump proneness existed in coal seam while strong bump proneness in rock and floor rocks in Tianchi Coal Mine.
