  • River Sand Mining and Mining Methods SpringerLink

    2014-6-13 · Abstract. Large-scale sand extraction from river environment for building constructions is a global phenomenon. Indiscriminate sand mining imposes a series of physical, ecological, and socio-environmental impacts on the river basins.Development and improvement effectiveness of sand,2017-12-1 · The sand injection-type SCP method is a method to densify the target ground by pumping and injecting fluidized sand into the ground through a small-sized equipment. A mixture of sand and a fluidizing reagent is forcibly ejected by pumping from the tip of the rod which is penetrated into the ground to densify the surrounding ground.
