ABSTRACT
Purpose. Substantiation of resource-saving technologies for supporting and protecting mine workings during their reuse for the purpose of multifactorial computer modelling and experimental tests.
The methods. Both experimental and numerical research methods were used in the research. The mine working state was assessed based on indicators of rock pressure manifestations in the form of drift contour displacements in key cross-sectional areas. Computational experiments on resource-saving supporting of prefabricated drift confirmed the effectiveness of usingrope crown runners in combination with the installation of a combined roof-bolting system.
Findings. The paper analyses the experience of supporting extraction drifts in Western Donbas. The parameters of supporting and protection systems were substantiated on the basis of experimental studies of rock pressure manifestations and modelling of geomechanical processes using the example of the1006 prefabricated drift of the Samarska mine, PJSC “DTEK Pavlohradvuhillia”. The computer experiment was conducted using the finite element method in the ANSYS software package. The complex of studies conducted has created an evidence base for the efficiency of using rope crown runners in combination with the installation of a combined roof-bolting system, which provides significant savings in material and labour resources at repeated use of mine workings.
The originality. Modelling of geomechanical mass around extraction workings was substantiated, conducted and analysed, taking into account innovative supporting and protection systems. The patterns of formation of protective armoured and rock plate depending on the parameters of rope bolts, taking into account the criterion of preventing roof rock stratification, have been obtained. Further research was conducted on the geomechanical system “rock mass – support” in the direction of studying the stress-strain state of rope bolts when they are connected by yielding lagging to the cap boards of the frames.
Practical implications. A scheme for resource-saving supporting the 1006 prefabricated drift at the Samarska mine of PJSC “DTEK Pavlohradvuhillia” has been developed and implementedin the recommendations, which ensures savings in material and labour resources at repeated use of the mine working.
Keywords: rock mass, mine working, supporting system, computational experiment.
