Evaluation of the stability of slopes with using native and foreign software
With permanent increasing of depth of open pit exploitation stress strain behavior of side array changes, so the choice of the necessary and corresponding to reality geomechanical scheme is an important issue. Currently,there is large number of software to estimation the stability slopes. This article provides a comparison of different programs based on numerical method and the method of limiting equilibrium.

Settlement-free technologies in the construction of the Saint Petersburg subway
Everywhere in Saint Petersburg the top strata are represented by quaternary deposits, and the ground water level is approximately 2,5 m down from the surface. Below the quaternary deposits, at depths of 40 to 60 m, are Cambrian (Proterozoic) clays. There are many ancient buildings of a historic and architectural value on the day surface that cannot tolerate day surface settlements. The construction of underground stations, and especially inclined escalator tunnels, causes surface settlements. Technologies of construction of escalator tunnels and station tunnels have been developed in Saint Petersburg to minimize such day surface settlements.

Historical analysis of the system of estimation and expert’s examination of explored ore reserves in Russia
Acting in Russia methodology of estimation and expert’s examination of calculated mineral reserves has been organized in the Soviet period, during development of the rigidly centralized system of the state planning and management. Since, 20 years there isn’t in the country any state monopoly (and financing) in the mining brunch and geological exploration. The new approaches are needed in procedure of estimating mineral reserves explored by the private enterprises. Anyway, functions, which the State Commission on mineral reserves (SCR) used to carry out in the Soviet time, remain nearly the same at present. Its full-scale authority, obligatory specifications are in clear contradiction with real economic relationship in the country. Computer modeling of ore bodies, composed on the base of geostatistical analysis of the exploration data, determines their natural contours and the ore grade distribution far more precisely than the formal index of the reserve’s category. There isn’t any necessity to approve in the SCR the so called group of the ore deposit complexity, nor the Technical-economic validation of limiting conditions. The mere procedure of the state approval of explored ore reserves ought to have the record keeping character.

- Authors:
- I. S. Pandul
Mine surveyor, using in his work the nominal system of rectangular coordinates, should know how to determine astronomical azimuth. The method of astronomical orientation based on the San observation is expounded in the article. This method is easy and not involving any information about exact time of observation. In addition, there is an example of calculating the azimuth of distant point.

The way of pipeline construction in areas of high seismic activity. Plates, which located on the ground surface and fixed in the ground by means of four supports, are used to compensate for the seismic loads. On each shoulder by a hinge to rotate in a vertical plane passing through the longitudinal axis of the pipe installed two-arm lever, one arm of which is oriented perpendicular to the longitudinal axis, and its hinged to tie attached to it, and the second arm is oriented at a right angle to the shoulder is directed along the axis of the pipeline and is pivotally connected to the rod.

The problem to increase of deposit oil recovery with difficult stocks high-viscosity oil and bitumens is considered. Results of experimental research to decrease the effective viscosity of oil samples and increase in mobility are considered at influence of superheated steam with addition in the heat-carrier of insignificant volumes of reagent (kerosene, diesel fuel) in 0,001-0,02 % of weight. It is recommended to apply thermal and plasma-pulse influence on a layer to increase of oil recovery. Results of practical technology application are given in several geological conditions.

Statistical evaluation of the energy rates of the surface miner MTS-250 (Germany)
- Authors:
- A. A. Grabovskii
Statistical estimation and statistical modeling of screw and cutter dynamic system that controls operation of the screw and vibrological impulsator of the surface miner of the type MTS-250 (Germany) is given. The statistical modeling is carried out using a digital model developed by the author as of the whole system and its individual components. This allows to vary the operating parameters of the surface miner and to evaluate the energy input per amount of the mined rock during the time of its work. This will eventually minimize the operating parameters of the surface miner.
