Within the building,air movement can be directed by roof form,thermal flues,and atria controlled by louvred openings.

在建筑内部,空气流通可通过屋顶形状,暖气管道和四周装有窗控制的调节。

Since the method causes serious depletion of ore during mining of upper plate,the inclined cutting raise heading together with inclined medium or deep hole kerve is suggested.

以无底柱为代表的崩落采矿法,切拉槽至关重要,而目前无底柱采矿大多采用垂直切与切平巷并配以深孔联合拉槽的切方法,但该方法在对矿体上盘回采过失贫化较大。
