Belonging to the Bentley Microstation series which work as one of the BIM platforms, the Bentley Power Rail Track shows huge advantages in the railway design for its visibility, high efficiency, advance, reliability and so on. This paper introduces the way to build the digital terrain model, alignments, cross sections, turnouts and to display the three-dimensional model of the railway for the Bentley Power Rail Track 3D railway design software. It provides application preparation for the BIM railway design and achieves the preliminary exploration of BIM applications. Bentley Power Rail Track proves capable of the BIM railway design.

The article presents a brief analysis of the key methods used for spatial modelling of mining and geological indicators describing the composition, structure and state of rock deposits. The main limitations of the analysed methods when applied under real conditions are outlined. It is proposed to overcome these limitations using Markov nonlinear algorithms. By applying the principles of multi-dimensional Markov modelling to a geological object, interval types were determined for modelling mining and geological parameters of the Elginsky coal mine. As an example, the article presents the results of predicting the ash content for the U5 section of the Elginsky coal mine on the basis of one of the cross-sections of the developed three-dimensional model.

Section Profile

This paper investigates the problem of assessing the degree of pipe deformation and the deviation of its longitudinal section profile from a cylindrical shape based on a three-dimensional point model of a hollow pipe under conditions when this model turns out to be displaced (rotated in space) relative to its real position. An algorithm for correcting a three-dimensional point model based on data on the current tilt of the camera is considered, as well as an algorithm for the actually obtained image overlaid with virtual cross-sections of the pipe, close to ideal.

Pipe Bending

In case of an unexpected increase in the storm during drilling at sea or in other emergency cases, the drill or casing columns are cut off with cutters of pretensioners and sealed wells. The drill string remains in the well and it is kept by the pipe plugs of the pretensioners. Blind rams are fitted with a cutting blade, cutting pipes in the well, allowing blind rams to seal the well. The task was to improve the cross-cutting preventer rams to increase the efficiency of the drill pipe cutting. The proposed modernization of the cutter design makes it possible to cut the drill pipe completely. In her, as in the previous design, the cutting process is the same, but due to the shape of the cutting surfaces there is no pipe bending, but a complete cutting. However, the difference between these structures from foreign is that in the process of cutting the pipe first, its point deformation (puncture) occurs with a cutter. This, incontrast to other structures, reduces the load at the initial moment of the tube deformation on the hydraulic cylinders of the pre-filter, and therefore, the energy costs for this cutting process are reduced, and the load on other elements of the drive is reduced by the pre-plate layers.Key words: antiviral equipment, plate preventor, cut-off rams, pipe bending, finite-element analysis. To study the cutting process of a drill pipe, a three-dimensional model of the pipe itself and two dies were constructed. The three-dimensional model is created with simplified, since with the increase in the number of elements is complicated as the construction of a network of finite elements, and the calculation process itself continues for a very long time. The results obtained by the simulation model show the effectiveness of the cutting of the drill pipe and the possibility of complete closure of the pre-cutter with cross-sections.
