Value chain stress resilience and behavioral strategies of companies in Russian coal industry
Autor: Е. V. Goosen, S. M. Nikitenko, V. I. Klishin, E. S. Kagan, Y. F. Patrakov
Publikováno v: Gornye nauki i tekhnologii = Mining Science and Technology (Russia). 7:330-342
Under the current conditions, the Russian coal industry is under unprecedented external pressure: it is both the imposed sanctions and the need to meet strict environmental requirements that inevitably lead to the closure of part of the enterprises,

Rock Mass–Multifunction Mobile Roof Support Interaction in Mining
Autor: L. D. Pavlova, V. I. Klishin, Yu V Malakhov, V. N. Fryanov, S. M. Nikitenko
Publikováno v: Journal of Mining Science. 57:361-369
The authors propose a dedicated mobile roof support for underground coal mining. Joint deformation of roof rocks and roof support is analyzed using the finite element method. The shapes and sizes of failure zones and the influence of the support on c

Paсker Sealing–Wellbore Interaction in Hydraulic Fracturing in Coal Seams
Autor: V. I. Klishin, S. V. Klishin
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

Active Prefracture Methods in Top Coal Caving Technologies for Thick and Gently Dipping Seams
Autor: L. D. Pavlova, V. I. Klishin, G. Yu. Opruk, V. N. Fryanov
Publikováno v: Journal of Mining Science. 56:395-403
The authors perform numerical modeling for the comprehensive stress-strain analysis of roof rocks above powered roof support units in the longwall top coal caving technology. Passive control of top coal prefracture fails to maintain efficient disinte
