The process of anaerobic fermentation of organic waste makes it possible to produce not only methane, but also hydrogen, which, when mixed, form a high-energy mixture - biohythane. The efficiency of biohythane production in a two-stage anaerobic fermentation process depends on many factors, including organic loading rate (OLR) and hydraulic retention time (HRT). It is known that the addition of an immobilizing support materials to anaerobic bioreactors improves the stability of their operation and increases the bi...

The technique of karst hazard assessment used on the territory of Ust-Kishert village is presented in the paper. We analyse the parameters of the research area natural structure which is characterized by the abundance of carbonate-sulphate karst. In this work, we consider karst rock mass as a certain volume of geological space occupied by the karstic rocks and the overburden (i.e. overlapping sediments) that are affected by the karst process. The purpose of this study is to identify the areas of local changes of o...

Deforming processes in areas of geologic failures (tectonic faults, boundary zones of block structures etc.) have the singularities in comparison with those, flowing past on "quiet" sites of rock masses. The intensive assimilation of underground space in most cases reduces in a modification of structural organization of a mining massif. In turn development of new structures or "revival" old is accompanied by adjustments on growing or available faults and is exhibited as strains of a surface and seismic pushes (in ...
