overlying rock

基本解釋

Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upwards into the overlying rock, and crystallize as they intrude.
巖基、巖蓋、巖堤、巖席等火成的侵入物向表層巖石推進，并在入侵過程中結晶。
This leads to a honeycomb of cavities that eventually collapse due to the weight of the overlying rock layers, leaving the irregular mounds standing.
這一現(xiàn)象會導致地下形成蜂窩狀的洞穴系統(tǒng)，并最終由于上覆巖層的重力而崩塌，留下一些不規(guī)則的巖石群。
During overlying rock strata being fractured, the surface gas drainage boreholes may be damaged due to ground movement.
在長壁工作面通過的過程中，地面垂直鉆孔可能隨巖層移動而發(fā)生破壞。
