Ore pillars are fasic units forming this deposit,the occurrence of which are coincident with the two sets of structure lines. 礦柱是組成該類(lèi)礦床的基本單元，其產(chǎn)狀與兩組構造的交線(xiàn)產(chǎn)狀基本一致。
As a result,the short hole shrinkage method with flat bottom structure was employed to mine the stope firstly,then stoping ore pillar by medium length hole caving method. 后溝金礦采用平底結構淺孔留礦法先采礦房，后用中深孔崩落法回采礦柱，經(jīng)兩年多的生產(chǎn)實(shí)踐，取得較好的技術(shù)經(jīng)濟指標。
