Abstract:

Purpose. To develop progressive technological schemes of the roof bolting for mine workings with respect to stress distribution around workings.

Methodology. Methodology of selection of the support system included the study of stress-strain state, rock pressure manifestations, conditions of working maintenance depending on mining-and-geological, mining-and-technological and mining-engineering parameters in order to determine their influence on the roof bolting efficiency and substantiate the support pattern; ensure stability and reduce deficiency and costs of driving and maintenance.

Results. The stress-strain state, mining pressure manifestations, conditions of working maintenance taking into account mining and technological parameters were studied. The study allowed us to determine the extent of influence of the mentioned factors on the efficiency of roof bolting support of workings.

Originality. We determined the consistent patterns of change of plastic range of stress and its evolution with time, the stability of working contours depending on mining-and-geological and mining-engineering factors, and the parameters for reliable operation of workings. Based on analytical modelling, the technology, systems and means for driving workings that promote decreasing the deficiency of contours were developed.

Practical value. The results of studies focused on development of the technology of intensive and safe working driving on the basis of the revealed regularities of the behaviour of the adjoining rock massifs were presented and optimization of the parameters of technological schemes of first workings were presented. They allow controlling the anthropogenic stress-strain state and raise the efficiency of the technology of marginal rock massif support.
