Description
技术领域 technical field

背景技术 Background technique
目前，砂矿开采的方法有三种，1、机械开采，直接用挖掘机进行挖掘来开采砂矿；2、高压水枪冲采，利用水的高压喷射把砂矿冲入集矿池，再用渣浆泵将集矿池中的矿浆泵送到选矿厂；3、采砂船开采，利用采砂船开采河床中的砂矿。 At present, there are three methods of placer mining. 1. Mechanical mining, directly digging with excavators to mine placer; The slurry pump pumps the ore slurry in the ore collection pool to the beneficiation plant; 3. Mining by sand dredger, using the sand dredger to mine the placer in the river bed.
尾矿是选矿厂选矿后产生的废渣，粒度一般在-200目占50~90%，从选矿厂出来的尾矿质量浓度一般在15%-45%，从选矿厂出来的尾矿堆存在尾矿库中，经过自然沉降，大部分水通过尾矿回水系统排走，剩下的尾矿水分含量在10~30%，在尾矿库中，尾矿的水分含量从地表向库底依次升高。 Tailings are the waste slag produced after mineral processing in the mineral processing plant. The particle size is generally -200 mesh, accounting for 50-90%. The mass concentration of the tailings from the mineral processing plant is generally 15%-45%. In the mine pool, after natural settlement, most of the water is drained through the tailings return system, and the moisture content of the remaining tailings is 10-30%. In the tailings pool, the moisture content of the tailings is from the surface to the bottom of the pool. raised.
随着资源的枯竭，尾矿再选成为目前资源替代的一种方式，目前国内外应用较多的回采工艺是机械开采、水力开采和采砂船开采，这三种回采工艺的共同特点是都需要人在工作面上操作设备以回采尾矿砂，而尾矿的特点是力学强度低，稳定性差，尾矿库浸润线以下的尾矿砂处于饱和状态，其力学强度更低和稳定性更差，这也导致以上三种回采方法回采尾矿时有较大的安全隐患。 With the depletion of resources, tailings re-selection has become a way to replace resources. At present, the mining processes that are widely used at home and abroad are mechanical mining, hydraulic mining and sand mining. The common feature of these three mining processes is that they are all It is necessary for people to operate equipment on the working face to recover the tailings sand, and the tailings are characterized by low mechanical strength and poor stability. The tailings sand below the infiltration line of the tailings pond is in a saturated state, and its mechanical strength is lower and its stability is worse. This also causes the above three mining methods to have greater potential safety hazards when mining the tailings.
