摘要
浅埋煤层薄基岩厚砂土松散层顶板动压灾害和采动水土流失是神东矿区急需解决的重大问题之一。顶板厚砂土层采动变形破坏规律是建立顶板动态结构理论的基础。通过动态相似模拟试验,揭示了厚砂土层破坏形态,并初步分析了破坏机理。
The vital problems to be solved in Shendong mine are the dynamic pressure damage of thin rock strata roof under thick sandy soil soft stratum and the loss of water and soil under mining.The mining deformation damage law of thick sandy soil over roof is the basis of setting up the dynamic structure theory of roof. The damage form of thick sandy soil layer was revealed and the damage mechanism was primarily analyzed through the dynamic simulating model test.
