strata behaviors

基本解释

Based on the spot observations, this paper analyzes the strata behaviors of fully mechanized face under the double hard conditions.
在现场观测基础上，分析了两硬（坚硬顶板，坚硬煤层）综放采场来压情况；
With the help of RFPA2D software, the strata behaviors of different parameters, softening factors and softening thickness of the stratum in a mine, are simulated numerically.
采用RFPA2D软件，数值摸拟了某煤矿浅埋厚硬关键层在不同注水软化主要工艺参数——软化系数、软化厚度情况下矿山压力的显现过程。

During mining, the stress behaviors of workface are very obvious. Thin rock strata of roof fall by full thick, procreant cranny reach the earth's surface and have clearly sidestepped subsidence.
在回采过程中，工作面矿压显现比较明显，顶板基岩沿全厚切落，产生的裂隙通达地表并有明显的台阶下沉。
