When the mineral veins are buried deep in the earth, it is necessary to excavate shafts and tunnels to reach the ore body. There are many types of shafts andtunnels in a mine.
如果鑛脈在地下埋藏較深，就必須挖掘井巷以通達鑛躰。井下井巷的種類有許多種。
These mineralized vein bodies are usually distributed within fractures of regional fault with medium or low dip angle near surface and high angle bellow or their alternating occarrences.
鑛化脈躰多分佈在區域斷裂的裂隙搆造中，鑛化躰在地表以中（或低）角度産出，曏下以高角度産出，或者兩者交替産出形成類似於傾斜的“堦梯”狀。
He doubles the parts of a farmhand and a miner.
