One of the promising trends in Kyrgyzstan mining is development of lode deposits. Such deposits were discovered and explored in the Republic as early as the last century. However, high-level mining has been started recently. This article gives a review of the available systems for lode mining in Kyrgyzstan. It is shown that lode mining involves increased dilution and high stripping ratio. This conditions comparatively high operating expenditures of mining using conventional technologies. Based on the outcome of the performed analysis, a concept of a new technology has been developed for thin weak ore body mining with large-diameter drilling. The key objective of the technology is higher efficiency and environmental safety of manless mining of thin ore bodies and creation of conditions for remote control of the entire production process. The proposed technology has been approved at commercial level at one of lode deposits in Kyrgyzstan. The test results have exhibited high efficiency and environmental safety of the technology.

Among the 70 types of worldwide natural hazards and phenomena causing severe harm to people and economy, more than 20 occur in the territory of Kyrgyzstan. The most destructive natural disasters include earthquakes, mudflows and floods, landslides and rockfalls, snow and glacial avalanches, movements and pulses of glaciers, stone streams, breaches of morainic and glacier lakes, heavy showers and snowfalls, subsidence and salinization of soil, groundwater elevation, etc. Natural and man-caused catastrophic events destabilize the economy of Kyrgyzstan and, in the context of budget gap, impel the government to divert a considerable part of the budget to eliminate consequences of disasters and render help to the population. The number of disasters and associated losses steadily increases. Consequently, the approach of forecasting and preventing natural and man-caused catastrophes and technologic emergencies is a highly topical, high-priority issue.

Rangelands occupy more than 80% of the agricultural land in Kyrgyzstan. At least 30% of Kyrgyz pasture areas are considered to be subject to vegetation and soil degradation. Since animal husbandry is the economic basis to sustain people’s livelihoods, rangeland degradation presents a threat for the majority of the population. We present for the first time an ecological assessment of different pasture types in a remote area of the Naryn Oblast, using vegetation and soils as indicators of rangeland conditions. We analysed the current degree of utilization (grazing pressure), the amount of biomass, soil samples, and vegetation data, using cluster analysis as well as ordination techniques. Winter pastures (kyshtoo) are characterized by higher pH values (average of 7.27) and lower organic matter contents (average of 12.83%) compared to summer pastures (dzailoo) with average pH values of 6.03 and average organic matter contents of 21.05%. Additionally, summer pastures show higher above-ground biomass, and higher species richness and diversity. Our results support the hypothesis that winter pastures, which are located near settlements, suffer from over-utilisation, while the more distant summer pastures are subjected to much lower grazing pressure. © 2016, Science Press, Institute of Mountain Hazards and Environment, CAS and Springer-Verlag Berlin Heidelberg.

We consider static, spherically symmetric equilibrium configurations consisting of fermionic dark matter nonminimally coupled to dark energy in the form of a quintessence scalar field. With the scalar field coupling function, the form of which is taken to meet cosmological observations, we estimate the effect of such a nonminimal coupling on the properties of dark matter compact configurations. We show that the masses and sizes of the resulting chameleon dark matter stars are smaller than those of systems with no field present. © 2013 American Physical Society.

The chigger mite Aboriginesia akimovi sp. n. is described. It was found in samples from Silver Mountain Vole Alticola argentata (Severtzov, 1879) captured in Ala-Archa Ravine (Alexander Mt. R., Northern Tien Shan). A species diagnosis, standard measurements, taxonomic remarks and drawings of the new species are included. A key to the five species of Aboriginesia from the Kyrgyz fauna is presented.

The direction choice of highway and railway routes is identified by an arrangement of mountain ridges and their spurs which, as a rule, are watersheds of basins. Depth of tunnel location and its direction are identified with rock properties, massif character, direction and magnitude of the main horizontal stresses. One of the most essential actions for increasing of efficiency of aseismic construction in mountain territories is choice optimization of an area of tunnel transition in mountain district taking into account seismic conditions. © 2014 Korean Geotechnical Society.

The opportunities of artificial neural networks model application to landslide forecasting are considered, namely prediction of landslide types and parameters of landslide damage area. The data collected by observers with different qualification are used as predictors, in doing so the reliability of prediction increases with higher professional skill of observers and accomplished research work. Real data from number of landslide-prone areas in southern Kyrgyzstan were used. © Springer-Verlag Berlin Heidelberg 2013.

Under discussion is rare-earth mineralization in Kyrgyzstan. Rare-earth metal zones in the Northern, Medial and Southern Tien Shan are described. Some deposits are characterized individually. The data on rare-earth reserves and resources are reported. It is emphasized that the primary task for the mining industry in Kyrgyzstan is recommencement of rare-earth element production. To this effect, it is required to reconstruct a processing plant at Kutessay-II deposit and launch a mining and metallurgical plant. Furthermore, it is necessary to continue deep-level mineral appraisal and to accomplish economical- And-geological re- Appraisal of remaining reserves of rare-earth elements in view of the current prices. Despite favorable possibilities of discovering large deposits, the territory of Kyrgyzstan remains yet to be explored in terms of rare earths. Most of rare earth deposits and mineralizations were discovered before the 1980s. Majority of the discovered rare earth deposits in Kyrgyzstan are unexplored and unappraised. Accessing from surface involved very few of them. It is topical to continue exploration and prospecting in the areas holding mineralizations and deposits of rare earths, and in the new zones suitable for rare earth discovery. With this end in view, the development strategy of the Republic should include a new program on integrated analysis, prospecting, exploration and mining of rare-earth elements.
