strata behaviors

基本解釋

Based on the spot observations, this paper analyzes the strata behaviors of fully mechanized face under the double hard conditions.
在現(xiàn)場觀測基礎(chǔ)上，分析了兩硬（堅硬頂板，堅硬煤層）綜放采場來壓情況；
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軟件，數(shù)值摸擬了某煤礦淺埋厚硬關(guān)鍵層在不同注水軟化主要工藝參數(shù)——軟化系數(shù)、軟化厚度情況下礦山壓力的顯現(xiàn)過程。

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.
在回采過程中，工作面礦壓顯現(xiàn)比較明顯，頂板基巖沿全厚切落，產(chǎn)生的裂隙通達地表并有明顯的臺階下沉。
