采砂船开采法有许多明显的优点,但也有些固有的缺点。最主要的缺点是:现行采矿工艺造成的矿砂损失大,用于对砂矿开采的完全程度和采砂船露天矿场参数测量的技术工艺和测量控制不够正确。在采砂船开采金属矿时,会产生松散的和原矿体的矿砂损失。松散矿砂的损失是由于采砂船露天矿场工作面的塌落和边帮滑坡,链斗式铲斗装得过满,矿砂撒落至框架缝内及采砂船开采时 Sand mining method has many obvious advantages, but also some inherent shortcomings. The main disadvantages are: the loss of ore caused by the current mining process is large, and the technical process and measurement control used for measuring the completeness of sand mining and the parameters of opencast mining of sand excavators are not correct enough. Sand mining in the mining of metal ore, will have loose and ore body ore loss. The loss of loose ore is due to the collapse of the working face of the opencast mining face of Caisson and the side slope landslide. The bucket-type bucket is overfilled. When the ore falls into the frame seams and the sand mining vessel is mined
