用汽车运输泥质物开拓含水砂矿床在很大程度取决于采区预疏干的程度。如果由于砂矿的水文地质和矿山地质特征不能保证有效疏干,则剥离工作将在不利的冬季,或在夏季进行。为保证自卸汽车夏季在含水砂矿进行生产,需沿基本渡线和在解冻的砂上修建主要 Car transport of muddy matter to develop water-rich sand deposits depends largely on the degree of pre-drainage. If effective dewatering can not be guaranteed due to the hydrological and mineralogical characteristics of the sand, the delamination will be carried out in adverse winter or in summer. In order to ensure that dump trucks are produced in hydrated sand mines in summer, it is necessary to construct major ones along basic ferries and on thawed sand
