山沟型尾矿库是在山沟谷口处筑坝构成的尾矿库。它的特色是初期坝相对较短，坝体工程量较小，后期尾矿堆坝相对较易管理维护，当堆坝较高时，可获得较大的库容；库区纵深较长，尾矿水弄清间隔及干滩长度易满足规划需求；但汇水面积较大时，排洪设备工程量相对较大。中国现有的大、中型尾矿库大多归于这种类型。
    清淤船即射吸式吸沙船，首要有浮体，料仓，吸沙泵，喷水泵，带水枪的吸沙龙头，上吸管，下吸管，动力，行走设备等构成。清淤船喷水泵把水经水枪直喷底层泥沙，泥沙在高压水的喷射下飞溅泛起在吸沙龙头周围，经吸沙龙头被吸沙泵吸起并由上吸管排入料仓。该船造价低价，运用简略，操作便利。适用于水底水草等缠牢物少的库区，河底，人工湖等处作业。
    抽沙机首要构造包含浮体、柴油机、抽沙龙头、手动卷扬机、抽沙泵、打水泵等六有些构成，选用主动与手动相结合的方式达到抽沙的效果，首要适用于石子比例不超越20%的疆场、河道、清淤等作业环境，每小时可抽沙30-50立方，沙子运送间隔150m，抽沙深度3-10m，具有体积小、造价低，能耗小，移动便利、操作简略，作业量大，易于运送等特色，是小型疆场、河道采砂的必备东西，是近几年采沙、清淤比较常用的东西。

The valley type tailings is located in tailings damming a valley mouth in the valley. It features is relatively short initial dam, the dam project was smaller and later tailings stacking dam is relatively easy to management and maintenance, when the heap dam is high, get greater capacity; reservoir depth is longer, tailing water clear interval and dry beach length to satisfy demand planning; but a catchment area with large flood equipment engineering quantity is relatively large. China's existing large and medium-sized tailings are mostly attributed to this type.

Dredger is shoot suction dredger, first and foremost a floating body, silos, sand suction pump, water pump, water gun belt of sand suction leading, straw, straw, drive, walk equipment. Dredger spray pump the water gun direct injection to the underlying sediment, sediment in the high pressure water jet splash appearing on the ceiling around the sand leading, the sand suction leading by sand suction pump suction and the straw into the silo. The low cost of the ship, the use of simple, easy to operate. For the river in the bottom water and other chanlao matter less, reservoir, artificial lake at work.
