苏联的“维新”竖井井筒的掘鍳,是由三处进行的,一处由地表向下,其余两处由102及205m水平坑道的导上天井(注)由下向上开鍳。而且由地表向下之屈鍳,与102m水平坑道之导上天井相会合,连接成一个竖井井筒。竖井井筒断面为圆形。直径决定为5m(见第1图)。混凝土的井框厚度为0.4m(即打洋灰的厚度),梯子、棚架及罐道均为木制,而中樑为金属所制。井筒总深度为291.5
Excavations of the shaft of the “Restoration” shaft in the Soviet Union were carried out in three locations, one down from the surface and the other two from the upper Patio (Note) up to the tunnels of 102 and 205m levels. And from the surface downward flexor 鍳, and 102m level tunnel leading to meet the courtyard, connected into a shaft shaft. Shaft shaft section is circular. The diameter is set at 5m (see Figure 1). Concrete box thickness of 0.4m (that is, playing the thickness of cement), ladder, scaffolding and tank are wooden, and the beam made of metal. The total well depth is 291.5
