五沟煤矿1011工作面开采“两带”高度发育的数值模拟分析

Numerical Simulation Analysis of "Two-zone" Developing Height in Mining 1011 Face of Wugou Colliery

摘要: 在分析五沟井田地质条件基础上,利用FLAC软件对开采引起的煤层顶板覆岩运移进行了模拟。据此分析研究了工作面覆岩破坏规律,确定了"两带"发育高度,利用简易水文观测法对模拟计算结果进行了验证,得出了1011工作面两带发育高度和规律的结论。

Abstract: Applying FLAC to simulating movement of roof caused by mining on the basis of analyzing geological conditions of Wugou Mine Field.Damage rule of overlying rock strata was researched and height of "Two-zone" was confirmed with this method.Observation result by simple hydrology method tested simulation result and the height and development rule of "Two-zone" in 1011 Mining Face were obtained.
