摘要
通过FLAC3D模拟实验方法分析10煤层在采动效应影响下顶、底板岩体变形破坏和矿压显现分布规律,并且给予了定量评价和预测,底板破坏裂隙发育最大值为22 m,为开采10煤层提供了理论依据。
The basic principles of the numerical simulation software FLAC3D were used to simulate the deformation of ten coal roof and floor was quantificational analyzed stress distribution disciplinet,he crack growth maximum was 22 m,thus have provided the theory basis for ten coal exploit.
