塌陷角
1.
Based on the characteristic of sink angle β (for med by the mining-empty region and the rock terrane above it),a definition of comple mentary sink angle α(α<90°-β) is made and a set of maths models are created.
本文根据采空区上覆岩层沉降塌陷角β的特性,建立外塌陷角a<(90°-β)的概念及一套数学模型,用来定性定量分析煤矿软岩巷道围岩压力显现规律和压力平衡条件,做到精确选择支护强度。

【诗文】:
楼观飞惊。好山环翠屏。谁向山中讲授,朱夫子、鲁先生。短檠。雪屋灯。琅琅终夜声。传得先儒道妙,百世下、以文鸣。见一阁本张小山乐府因不重录。
