Aim of the work is long-time monitoring of building reclamation mixtures on fly ash basis in pilot plant terms. The objective is to obtain a conclusive result set to prove that the interests of environment and people’s health protection are not endangered in the relation with natural geological surroundings by variant bulk mass mining technological utilisation in the area of open pit mines or a power industry. A rigorous assessment of the referential qualitative parameters of monitoring points environment is rep...

The utilisation of fly ash must be searched for because of its current production. One possibility of the use is at old mines liquidation, where the ash can be used as a consolidated filling material. The consolidated filling material consisting of conventional fly ashes consolidated by a hydraulic binding material is transported to a pit in a suitable slurry consistency which ensures the strength for definite pit sections up to 5 MPa. Common requirements on physico-mechanical qualities are the pressure strength m...
