The paper discusses intercompany cooperation, with particular attention to the innovative business. Initially partnerships are understood as an element of company's relational resources. External relations are selected from the whole set of partnerships; we analyze their influence on the competitiveness of a firm. Various forms of partnerships could be found within industrial markets, and generally they are very flexible. Besides traditionally defined market and hierarchical mechanisms, there are some hybrid schemes. The article shows that these hybrid schemes act as a form of so-called «quasi-integration» between companies, which enables them to obtain certain advantages of integrated structures and retain their legal entity status. According to our hypothesis, cooperation model choice is dictated by several factors, including company's characteristics, market structure, and the specificity of assets. Also, we analyze partnership relations of businesses that are included in the national rating «TechUspech», as well as the cooperation between a few small and medium-size innovative companies in Siberia. The study results have revealed that firms related to the knowledge economy and those dealing with oil and gas sector use complex hybrid schemes of quasi-integrative cooperation with a wide range of partners being involved. Despite the widely acknowledged importance of partnership for innovative companies, in most cases, this kind of relations develops spontaneously. Regular partner relationship management does not exist yet. Many innovative companies consider large domestic and foreign corporations as reliable main partners; therefore, these agents play a significant role in the innovative economy.

The article deals with a new phenomenon of a sustainable industrial area. Within the paradigm of sustainable development, some companies have already used the corporate social responsibility concept. As far as the whole industrial areas are concerned, there existed no similar concepts. The article outlines theoretical foundations for the concept of a sustainable industrial area. In particular, we are referring to the three dimensions of sustainable development. This approach offers great opportunities for mutually-beneficial cooperation between enterprises, especially for small and medium-sized ones. As part of this concept, together they can make a significant contribution to sustainable development, which they could not make individually. A case study of Germany shows approaches to designing a sustainable industrial area. We also present a new concept of the stability triangle that allows approaching this issue in a consistent manner.

The article suggests a method for the early assessment of gross regional product (GRP) based on operational statistics, which allows obtaining this indicator one or two years before it is publicly released. It presents the results of test calculations and estimates of the precision of the proposed method for the assessment of GRP.

Aiming to build up a phenomenological basis for the theory of interaction between geomechanical, thermal and physicochemical processes in methane-bearing coal in Kuzbass, the authors have performed a set of laboratory bench tests on uniaxial stiff loading of various rank coal specimen to failure at a rate of 3.3∙10-6 m/s. The pressure versus temperature dependences are obtained for coal specimens with granite interbeds using high-precision computerized thermal scanner. It is shown that temperature change in coal specimens subjected to loading to failure is connected with volatile yield and internal energy relaxation of methane in Kuzbass coal. Using jointly thermal imaging and laser measuring equipment ALMEC-tv for high-precision and detail control of deformation-wave processes in loaded coal specimens by speckle-method, it has for the first time been proved that nonlinear pendulum-type movements of structural elements are possible in coal specimens under varied temperature field, which is of fundamental importance for actualization of previously ignored mass and gas exchange processes in high-stress different-grade coal seams under mining.

The full-scale measurements of initial stresses and numerical modeling of stresses in rock mass enclosing deep open pit mine Zhelezny under planning at Kovdor Mining-and-Processing Integrated Works are presented in the article. The authors have located hazardous areas in pit wall rock mass and validated stability conditions for pit walls with vertical benches.

In the framework of the developed and implemented nonlinear geomechanical model of a coal seam having block structure to describe gas influx in borehole, the authors propose the method for quantitative estimate of gas content and diffusion and mass exchange coefficients based on solution of inverse problems using pressure measurements taken in shut-in borehole in the “pressure drop” mode. Besides the main function, the set problem had an auxiliary objective function with the less number of arguments. Numerical experiments with synthetic input data show that the auxiliary objective function has a number of local minimums. The authors also put forward a technique of finding global minimum that provides the set problem solution.

The issues of calculation of stresses and strains in the elements of support and in rock mass in stagewise drivage of a production face are under discussion. In order to take into account sequences of mining and support installation, it is required to solve problems on extra stresses due to small cross section drivage. Geomechanical estimation of support and rocks used the method based on single-stage formation of stiffness matrix to describe rock mass prior to mining start. Sequential drivage of excavations and change of mechanical properties in the calculation system are modeled using initial stress procedure. The author calculates two scenarios of mining with stagewise face drivage under conditions of elastic deformation of rocks and support and analyzes behavior of stress redistribution in elements of support being installed in stages. It is shown that mining sequence considerably influences stresses in support elements upon drivage completion. The scenario of mining with initial installation of sideways support elements results in increased tensile stresses in the support as against the scenario when the underroof space is cut and supported in the first place.

The authors describe mathematical model for estimation of cone-type pitwall stability in the framework of rigid-plastic deformation of rocks, with finding safe ultimate pit depth.

The article describes modeling procedure and calculation of wave fields in microseismicity monitoring in anisotropic medium. The research findings are intended for testing of processing algorithms for data of seismic observations in underground mining.

The procedure to estimate growth in load exerted on interchamber pillars with time is based on mathematical modeling of stresses and strains in structural elements of room-and-pillar mining method using roof rock failure criteria. The calculation results illustrate a real time scale of variation in strength of rocks and the associated partial collapse of a parting and failure of edges of interchamber pillars when their height is increased.
