The results show that ( 1 ) the unconsolidated confined aquifer plays a crucial role in load transfer because of its fluidity and replenishment in time, making the loads of overburden soil evenly transfer into the bedrock through the unconsolidated confined aquifer and the load keep constant during the excavation process ; ( 2 ) under the condition without unconsolidated confined aquifer, the load on the bedrock will be reduced sharply during the excavation
研究結果表明：鬆散承壓含水層條件下，由於承壓水的流動性和補給作用，上覆表土層的載荷通過鬆散承壓含水層均勻地作用於下部基巖上，開挖過程中基巖頂界面上的載荷基本保持恆定，鬆散承壓含水層起到均勻傳遞載荷的作用；無鬆散承壓含水層時，作用在基巖頂界面上的表土層載荷隨煤層開挖而顯著降低。 -
Therefore, in the process of load transfer within the unconsolidated confined aquifer, the key strata of overburden rock are prone to have a compound breakage when the load on the upper interface of bedrock is great and the bedrock is very thin
在鬆散承壓含水層的載荷傳遞作用下，作用在基巖頂界面的載荷較大，當基巖厚度較薄時，采場覆巖關鍵層易產生復合破斷。
