Paсker Sealing–Wellbore Interaction in Hydraulic Fracturing in Coal Seams

Publikováno v: Journal of Mining Science. 56:547-556

The process flow chart of hydraulic impact on coal and rock mass is examined. The double-sided packer design is presented for the implementation of the chart in uncased wells of large and varied diameters. The laboratory tests of axial displacement o

Stress State of Conical Granular Pile

Autor: S. V. Klishin, A. F. Revuzhenko, A. P. Bobryakov

Publikováno v: Journal of Mining Science. 55:876-882

The authors analyze the effect revealed at the Institute of Mining, SB RAS in the 1970s. This effect consists in a noticeable off-center displacement of the maximum normal pressure on the bottom of a conical pile when heaped. The new experimental dat

Methodology of experimental determination of mechanical impedance of vibration-insulating branch pipes taking into account flexibility of test facility at lengthwise vibrations

Autor: A. V. Zubarev, A. A. Shvarts, D. V. Sitnikov, S. V. Klishin

Publikováno v: Journal of Physics: Conference Series. 1441:012096

In the problems of vibration isolation of hydraulic system units, such as pumps, an important role is played by the problem of oscillation propagation through unsupported connections (pipelines). In order to solve this problem, in particular, rubber-

A class of vortex flows in granular medium

Autor: S. V. Klishin, A. F. Revuzhenko

Publikováno v: Journal of Mining Science. 51:1070-1076

The authors study numerically a problem on vortex flows in bounded domain in granular material using discrete element method. The granular material is composed of spherical particles with the assigned distribution of radii. Dry friction and rolling r

Numerical analysis of plastic behavior of granular media exposed to deformation under broken path loading

Autor: S. V. Klishin, A. F. Revuzhenko

Publikováno v: Journal of Mining Science. 51:951-956

Based on DEM, the problem on uniform shearing of granular material specimen is considered, the shape of the particles was chosen to be spherical, with assigned distribution per radii. At interfaces of the particles, dry friction and viscosity were ta
