煤矿开采沉陷移动变形预测

To Forecast Mining Subsidence Removing Sharp in Coal Mine

为了预测评价开采沉陷对矿区环境的影响 ,正确选择环境保护措施 ,必须对开采沉陷引起的地表下沉、倾斜、曲率、水平变形等移动变形值、地表移动持续的时间和最大下沉速度、开采沉陷的范围、冒落带和导水裂隙带的高度以及采动过程中地表移动变形等进行预测 ,本文将介绍几种预测方法。

For forecastion and evaluating influence of mining sudsidence on mine area environment,correctly selecting environment protective measures,the surface remvoving warp caused by mining subsidence should be forecasted,this paper introduces a few kinds of forecast methods in coal mine.
