Research work was carried out at the Zhezkazgan field (Annensky district), Kazakhstan.
Geological object of Annensky district field was considered with the assessment and analysis of its spatial heterogeneity. Quantitative assessment of heterogeneity was carried out with detailed studies, i.e. covered local objects and structures. State medium- and large-scale geological surveys and development of new geological data analysis methods have created the conditions for a quantitative approach to the assessment of local and regional spatial inhomogeneities.
Datamine program is the leading global software for the industry of natural resources. We used it to make data and analysis, research, geology, geochemistry, rock mechanics, surveying, ore body modeling, the design of underground mines and quarries and production planning, and in the fields relatedto the study of the environment.
To work with well data source file is read into the database. A wide range of formats of data sources were used to import external data files, which are available through the Import command in the Data menu or the Import button in the toolbar. The studies used file-sources, which are four text files containing information about the location of wells and sample wells and properties orientation.
Contouring was conducted from the extreme southern section to the north at regular intervals.
One of the methods of studying the regional spatial inhomogeneities is spatial and statistical analysis.
Spatial and statistical analysis is based on the record of structural complexity and further tested by Jeffrey De-Vignala. The technique has confirmed the presence of pre-existing deposits (Pokrovsky, Krestovsky), and also revealed the presence of prospective area in the north-eastern part, dedicated to the siltstone-sandstone complex. In the course of geochemical studies carried out on the results of channel sampling faces three horizons (220, 120, 90) of copper and silver distribution maps were constructed. The investigations led to the conclusion that the useful component anomalous values correspond to places of tectonic faults and flexures.
The article focuses on the construction of retaining walls to ensure safety on mountain roads during the development of mountain territories. It also examines protective structures, which are currently in use on the roads of Caucasus mountains. Special attention is paid to the effectiveness of their use on roads of South Ossetia, which are already constructed or are under construction, including Transkam and on the road Tskhinvali – Leningor.
Protective retaining walls are constructed to retain the unstable soil mass from collapse. In transport construction retaining walls are installed on steep slopes and slopes mainly for protection of roads and railways.
At present stage in conditions of the Caucasus one of the laid roads, as a result of omissions and mistakes in calculations of the project implementation, was not provided with the calculation of a base strength and the pressure force of zapazushnoy dirt mass brought the wall in a sloped condition, creating the risk of an emergency. Consequently, designed massive retaining wall came in an unstable condition, reducing the road safety.
Poorly constructed retaining walls instead of providing safe driving conditions create emergency situations, such aschunks or lumps of rocks, which jump over the retaining wall and fall on the roadway.
Detailed monitoring and analysis of operation of the retaining walls shows in certain conditions they were ineffective, as zapesochnaya space is filled with mass of wet soil, which pressures the wall and leads it to an unstable state. Parallel to this the possibility of harvesting of zapashny ground in a mechanized way is complicated, that is one of the main negative factors of protective retaining walls operation.
As a result of a survey of the operating conditions of retaining walls on mountain roads of the Caucasus we can conclude:
1. The use of retaining walls should be justified in technical, economic and environmental terms; the efficiency of road traffic safety is also very important.
2. Design of retaining walls, working in conjunction with the soils in the embankment subgrade and zapazushny space are technology-savvy, convenient and efficient in structural design, but their use should be considered from the point of view of their relevance in the safety and protection of roads from collapse of slope landslides, landslide-screes and other hazards.
