Monitoring of the state of vegetation of oil producing areas of Western Siberia for the period 2010-2015 using thematic products MODIS are carried out. The approach is suggested to assessment of the impact of various factors on the environment areas of oil and gas on the base of remote sensing data by NDVI. Testing of the approach undertaken for the technologically-disturbed areas of four oil fields in Tomsk region - Krapivinsky, Ladyzhensky, Luginetskoye, and Urmanskoye. Additionally, as the background area, the area of ​​the State nature reserve of regional importance “Oglatsky” is studied.

Twelve air temperature and humidity measurement series were carried out with the use of AKV-2 mobile station in Tomsk and its suburbs in different seasons and under different weather conditions. The urban heat island effect is shown to be observed in Tomsk in all seasons; the mean temperature increment is 2 °C in winter and 1 °C in summer. The fields of absolute humidity differ significantly for warm and cold seasons in Tomsk. It is shown that the humidity in Tomsk is mainly of anthropogenic origin in winter and of natural origin in summer.

The relative contribution of different factors into formation of the urban heat island in Tomsk is estimated. It is shown that the key factors are anthropogenic heat emissions (80-90% in winter and 40-50% in summer) and absorption of short-wavelength radiation by the urban underlying surface (5-15% in winter and 40-50% in summer), while the absorption of long-wavelength radiation by the underlying surface, absorption by moisture and admixtures, and heat loss on the evaporation contribute insignificantly. It is shown that the turbulent heat flow prevents a linear increase in the intensity of the urban heat island with an increase in the sum of radiation fluxes that ensure the energy income into the heat island region. Due to an increase in the turbulent heat flow in Tomsk, 40-50% of the absorbed energy is carried over in summer and 20-30% in winter. An equation is suggested that allows calculation of the heat island intensity in different seasons, time, and under different atmospheric conditions from weather parameters measured at a stationary site.

A narrowband VUV radiation (near a wavelength of 147 nm) corresponding to optical transitions of the heteronuclear dimer ArXe from plasma formed during the excitation of the Ar-Xe mixture at a pressure of 400 mbar with high-voltage nanosecond discharge initiated by runaway electrons was registered. Amplifying properties of the discharge plasma with respect to this radiation were found.

Particular properties of formation of the optical field in the composite spherical microcapsules of different size consisting of a polymer absorbing shell and a non-absorbing liquid core are presented. The numerical simulation shows that changes in the thickness of the shell, grown on the core fixed radius, and the coefficient of its own radiation absorption determine the nature of spatial distribution and amplitude characteristics of the absorbed power. Variations in these parameters allow changing position and peak values of the areas of the effective absorption volume of the particle and, consequently, create conditions favourable for opening the shells in the appropriate spatial areas. This is important for the solution of practical tasks associated with the problem of release of the contents of the microcapsules.

The calculations results of LED light intensity necessary for reliable visual detection of runway lights in field conditions are presented. The following groups of LED lights are considered: approach threshold lights, lights of the last 600 m of a runway, and runway end lights. Detection threshold were chosen. The effectiveness of LED lights is analyzed in different weather conditions during the night, at twilight, and in the day time, and questions of speed adjustment of LED radiation intensities in accordance with ICAO standards are considered.

The article focuses on efficient analysis and test methods to determine nano- and micro- physico-mechanical properties of rocks and crystals. A modification of the classical elastic problems of contact mechanics implemented using the mathematical apparatus of fractional integro-differentiation is proposed. The authors build new models and algorithms aimed to advance the studies into properties and states of geomaterials based on the atomic-force microscopy techniques, and describe testing of the new approaches in calculation of the elastic modulus for hydrocarbons with nano-additives.

The analytical review covers the key factors that influence permeability of a coalbed under mining-induced alteration of stress state. The authors put forward an analytical relation between coal permeability, stresses and adsorbed gas to define parameters of gas leakage zone parameters and laws of mass-transfer. The analytically derived relation is compared with the known model of coal structure and with the experimental results. The proposed model of coalbed permeability allows mechanism of leakage and localization of seepage zones in coal provided that the model parameters are properly selected or found experimentally.

The article offers in situ test methods for cohesion and internal friction angle in rocks and at joints. Technologies and instrumentation for shearing of rock wedges in an open pit mine and for laser scanning and digital imaging of local falls and breaks of inaccessible rock blocks in pitwalls have been developed and approved for constructing of a limit equilibrium equation and for calculation of strength properties of rocks and joints. Rock wedges for the tests are prepared using various design drill rigs, the rock wedges are sheared using a 40-t jack placed in a special metal housing with an electric hydraulic pump. Exploration of inaccessible local falls in pitwalls uses electronic tachometers and 3D mine scanner. The tests and approval of the described exploration techniques have been carried out in open pits in Kazakhstan and Kirgizia.

The scope of the article encompasses features of natural and induced seismicity and the change in frequency plots when natural seismicity becomes natural-and-induced seismicity in mining areas and when induced seismicity becomes natural-and-induced seismicity in mines. It is shown how induced seismicity is connected with the subsidence of overlying strata in mines-seismic process propagates together with the subsidence but seismic activity lowers in the time of maximum subsidence and intensifies when subsidence ceases or decelerates. The authors lay emphasis on estimates of seismic activity in mines and give details of an integrated index F procedure tested in mines and adjusted within the 10 year-long period of application.
