一九七九年来露天矿主要道路的质量有了明显的提高,尤其是Ⅶ(?)运矿道路。它是由采场堑沟口到选厂矿仓,全长1200米的生产干线,也是矿区通往外部的主要公路之一,因而车辆密度很大。七九年以来,路面平直,晴天灰尘少,雨雪不泥泞,车辆行驶平稳,速度大大提高,发挥了汽车应有的效率,降低了材料消耗,促进了生产的发展。 Since 1979, the quality of major open-cut road has been significantly improved, especially Ⅶ (?) Transport road. It is from the cutting field Mizoguchi to the election plant ore warehouse, a total length of 1,200 meters of production lines, but also the mine leading to the outside of one of the major roads, and thus the vehicle density. Since 1979, the road surface has been flat with few dust on the sunny day, the rain and snow are not muddy, the vehicle runs smoothly and the speed is greatly improved, the proper efficiency of the automobile is exerted, the material consumption is reduced, and the production is promoted.
