THE ALTERNATING TEMPERATURE EFFECTS AS A FACTOR FOR ENERGY SAVING TECHNOLOGIES OF COMPLEX PREPARATION OF RAW MATERIALS IN PERMAFROST CONDITIONS
The paper presents the results of experimental researches of influence alternating temperature effects on destruction of rock samples. It was found that the mechanism of disintegration of rocks develops due to the formation of non-uniform in the volume of rock stresses; the maximum values of these stresses are associated with the degree of saturation of the pore space of rocks by moisture. Conducted model estimates the alternating temperature treatment on the occurrence of wet particulate material rock stress-strain state. As the main mechanism of the physical destruction of rocks considers formation of internal mechanical stresses due to non-uniform across the section of a piece of rock by ice. They can act as a controllable parameter process heat and mass transfer at alternating temperature influence to create a non-uniform stress. The experimental and calculated data show significant effects of alternating temperatures and initial moisture content on thermal stress state of the particulate material rocks. They can be used to reduce energy consumption for destruction of rocks, as well as serve as a basis for the development of energy-saving and efficient technologies for processing mineral resources (crushing processes and concentration) increase the disclosure mineral grains.

MICROSTRUCTURE AND SPECTROSCOPIC STUDY OF PERIODIC MICRO- AND NANO-STRUCTURES THAT OCCUR ON THE SURFACE OF AMORPHOUS AND CRYSTALLINE SILICA UNDER RESONANCE RADIATION CO2-LASER
At present great attention is paid to the phenomenon of quasiperiodic structures on the surface of solid materials under action of pulse laser radiation in visible and near infrared range. Forming nanostructures modify physico – chemical properties of the surface, which is of great interest for many technologies. This work was traced a link between the process of formation of the relief of periodic structures and structural changes occurring on the surface, provided the resonant interaction of laser radiation with matter. The resulting surface defects was studied by the methods of optical microscopy, atomic force microscopy (AFM), method of infrared (IR) spectroscopy. As objects used samples of crystalline and amorphous quartz irradiated by pulsed CO2 laser. The pulse duration was 70 nm, pulse energy of 1J for single-mode and 210 MJ for multimode regimes. In the result of the researches it was found appearance of the two types of surface periodic structures – micron with a threshold of occurrence of 5.2 J/cm2 and nanostructures with a period of 100–150 nm, and a threshold of occurrence 40 J/cm2. In single-mode and multimode impacts (energy flow, respectively, 40 and 48J/cm2) occur nanostructures depth of the relief which depends on the frequency of laser irradiation. In a single-mode regime of these nanostructures have less depth. The formation of the relief on the surface is connected with intensive ablation in the field of high standing wave, formed in the result of interference of the incident and surface electromagnetic waves arising in resonance absorbing medium.

STABLE MOTION OF RIGID ROTOR ON ANTIVIBRATION SUPPORTS WITH SLIDER BEARERS
The author examines behavior of a rotor mounted on antivibration supports with slider bearers. The supports consist of two-stage shock absorber, packing piece and vibration absorber. As the first stage of shock absorbing, it is suggested to use an oil film. This greatly simplifies the design of the antivibration unit. However, the oil film may essentially affect dynamics of high-speed rotor machines. Moreover, the effect of weight and rigidity of supports on the change of the stability ranges of rotors can also be high. Major difficulties in calculating stable motion of a rotor with an oil film are connected with determination of rigidity and damping effect. In a general case, hydrodynamic forces arising in the oil film represent nonlinear functions of coordinates and velocities that govern the rotor position. The author uses linearized expression for hydrodynamic forces as rotor makes fine movements. Under consideration is one-dimensional model of rotor vibration on antivibration supports. For constructing stability ranges for a rigid rotor on rigid supports, a characteristic biquadratic equation is derived. The search of the stability uses the Hurwitz criterion that allows finding both the boundary and area of the stability range of rotor. Stability conditions for rotor on antivibration supports are determined, and the relevant characteristic equation is constructed. The stability ranges are constructed using the Division Method D. The level of the effect exerted by elastic-inertia characteristics of antivibration supports on the change of the rotor stability ranges is assessed. This reduces the self-excited vibration probability and enhances efficiency of antivibration supports.

ENHANCEMENT OF RELIABILITY, SAFETY AND EFFICIENCY OF MINE HOISTS
The analysis of the condition of safety brakes of mine hoists shows that, first, the safety brake is still imperfect as it has no backing-up and, second, none of mine hoists support maximum allowable deacceleration of 5 m/s2.
Without the maximum deacceleration, the deceleration track is longer, which has an influence on height of the head frame (load lifting) and on depth of the sump (load-lowering). The longer deceleration track is unfavorable since when a downgoing vessel is jammed and an upgoing vessel continues moving the rope becomes loose and coils on the jammed vessel and when the jammed vessel takes-off the rope breaks, which has sometimes been observed.
Inspections of safety brakes in some mines discovered attempts made towards improvement of deacceleration by reducing the blank run time tbr from tbr = 0.5 s to tbr = 0.2 s and raising statistical reliability factor from Кsr = 3 to Кsr = 4.37. Unexceptionally, deacdeleration value grows but is still less than the allowable 5 m/s2.
The author notifies that with the higher deacceleration due to increased Кsr, the wear and tear of brake shoes grows, i.e., their life length shortens.
It is also mentioned that the safety brake operation mode has material effect on remaining life of shell of coiling machine that services two-drum mine hoist.

APPLICATION OF CEMENT SLURRIES WITH MICROSPHERES IN CRYOLITHOZONE WELLS
Hole fixing in areas with harsh climate is a complex technical problem whose solution requires the use of special technical means and technological methods. During the construction of wells in such conditions lightweight cement slurries are widely used that minimize the risks of possible complications. From introduced into the cement slurries lightweight compounds, microspheres can be distinguished because they characterized by low density, high strength and low thermal conductivity values.
This article provides an overview of the microspheres commonly used in the practice of well cementing. It is noted that an additive in the cement slurry of microspheres reduces the density at a relatively low water demand, and cement stone formed with inclusion of the microspheres has a low thermal conductivity and enhanced fracture toughness.
Based on the analysis it is concluded that the input of microspheres allows to obtain a suitable cement stone for fixing wells in permafrost.
