In the course of working off of mineral deposits, which is carried out basically by open way, huge quantities of technogenic waste is accumulated: overburden rocks, discarded ores and tails of ores enrichment. The given waste includes two interconnected components: mineral-raw and ecological. From geological industrial positions they are potential secondary mineral resources. From ecological position they are sources of environment pollution. In RA has been collected and large quantity of mining waste continues to be accumulated, the wrong policy to which can lead to rather difficult situations.

In this work for the first time an attempt for collection and analyses of the results and data of researches on block structure of the earth crust of the territory of Armenia and adjacent regions are made. In the result of these researches unsolved problems were revealed and the ways of their solutions were offered. Concrete suggestions and ways of their solutions are brought. From these suggestions the main points are the definition of «block of the earth crust» conception, taking into account the depth structure of the earth crust up to 20 km and recommendations on ranking of blocks.

The principles of three-dimensional groundwater modeling are considered in the article. It is noted that the basic program of groundwater flow simulation was developed by McDonald M. and Harbaugh A.W., which is called Modflow. In this paper on the basis of lithological sections of the wells drilled in Yerevan Basin the transition from lithologic layers to generalized layers on their permeability has been conducted, i.e. layers with similar permeability properties are linked in a single layer. As a result, for Yerevan Basin three layers have been obtained: water-bearing, confined and slowly permeable.

The process of collecting, organizing, filtering and computer background database, the definition of the velocity parameters of seismic waves for assessment of stress-strain state in Ararat seysmopoligone are presented. The errors of calculated parameters (V_P/V_S) and the statistical analysis of the mean velocity parameters for all the stations of seismic network of RA are evaluated. The average of the Ararat range is clarified and statistical hypothesis testing compliance with the calculated real value is performed.

Weather-climatic researches in the area of «Erebuni» Airport (Yerevan City) showed that cloud cover up to 500 m and lower is observed and can remain in following conditions: relative humidity of air is not less then 88%, the dew-point deficit to 4℃ and wind speed is 2–3 m/s with maximum to 5 m/s. The forecast of low cloud cover in the area of «Erebuni» Airport is made by synoptico-statistical method. Application of this method over very short range (up to 12 h) and nowcasting (from some minute to 3 h) the forecast provides about 80%, short-term (to 72 h) the forecast 70–75% were proved.

The article discusses the main principles and approaches to determine agro-tourism as a segment of tourist activities. In the article we tried to distinguish nature-oriented types of tourism, i.e. eco- and agrotourism as parts of sustainable tourism conception that means usage and longtime maintenance of natural resources.

In the paper the main issues of life quality relationship and the settlement is observed. The population life style and its space-time manifestations as components have a systematizing impact on the settlement, significantly causing its functional hierarchy. In the article the settlement as one of the factors causing the territorial differentiation of population life is discussed. On the example of Shirak Marz an attempt to highlight the regional population life quality and to determine their association with the quality and location of settlements is done, as well as the functional structure and place in the settlement system.
