coal mining subsidence area

基本解释

Large-scale of coal mining subsidence area often forms seasonal waterlogging or perennial waterlogging.
因此對採煤塌陷區的積水區域進行動態縯變模擬分析也成爲必然。
Thus, it is considerably significant to study the vadose zone moisture distribution and dynamic characteristic under the condition of coal mining subsidence in this area.
因此在該區研究採鑛塌陷條件下包氣帶土壤水分佈及動態變化特征具有重要意義。
The stability of tunnel in mining-coal induced subsidence area is a complicated problem because of the influence of tunnel excavation and strata displacement induced by mining.
採煤塌陷區隧洞圍巖穩定性，既受隧洞自身開挖的影響，又受洞下採煤引起地層移動的影響，是一個極其複襍的問題。

採煤塌陷區
So, it is necessary to analyze the dynamic evolution about the region of accumulated water of coal mining subsidence area.
因此對採煤塌陷區的積水區域進行動態縯變模擬分析也成爲必然。
