“…It is also important to analyse the peculiarities of the subsoil use development in the region, taking into account its infrastructure and the possibilities of processed products utilization, as well as the ecological situation [53,54]. In this particular case, the implementation of integrated development in an existing quarry is much cheaper, and the time spent on the new technology introduction can also be reduced.…”

This paper presents the research results of the pulp movement process along the extraction chamber bottom to the suction pipe of the pulp lifting device in case of downhole hydraulic mining the volcanic tuff-stone. The washout process and hydraulically operated transportation of the tuff-stone hydraulic mixture, when forming the extraction chamber, have been studied under various conditions and methods of exposure. As a result, the dominant parameters have been determined influencing the hydrodynamic washout technology as well as tuff-stone hydraulic mixture lifting to the alluviation map. The dependences have been substantiated of the washout process performance and transportation capacity of the hydraulic mixture flow on the determined parameters. To calculate the process of pulp flow-over along the extraction chamber bottom to the intaking hydraulic elevator headwall, the systems of equations have been determined based on the modelling the movement of tuff-stone hydraulic mixture along the extraction chamber bottom during hydraulic washout. The dependences of the contact strength of the tuff-stone samples mined by downhole method on the time spent in water are presented, resulting in determination of the tuff-stone weakening coefficient and the degree of its saturation with water.

“…The main sources of water reservoirs contamination are the discharge of insufficiently purified wastewater from industrial and communal enterprises. A large source of water pollution is the dumping of significant volumes of water from mines [1]. This leads to the contamination of surface water objects with substances contained in water from mines.…”

“…Ukraine is characterized by both quantitative and qualitative depletion of water resources due to their pollution resulting from the discharge of huge volumes of incompletely treated mineralized water. Heavy metals can infiltrate into the natural sources with wastewaters of different production of chemical and heavy industries; they can interact with other compounds of water and exhibit toxic effects towards living organisms (Duruibe et al 2007, Buzylo et al 2018.…”

Spent Biosorbents as Additives in Cement Production

et al. 2020

The research is related to solving the problem of rational use of materials and to the creation of resource-saving technologies for the protection of the environment from pollution. Sorption technologies are quite effective in wastewater treatment, but most sorbents are quite expensive, and their regeneration raises the question of recycling of spent solutions. The cheapness and availability of raw material base of biosorbents makes these technologies attractive for wastewater treatment. The research is aimed at investigation of the ways to effectively utilize the spent sorbents, which are obtained after water purification, in the production of building materials. The obtained results allow creating a complex low-waste technology of water demineralization and purification from heavy metal ions.
