Abstract

The improvement and introduction of advanced technology and means of fixing mine workings with justification of their optimal parameters based on the consideration of the stress-strain state of the host rocks will reduce material and labor costs during their operation.When working off coal seams during the periods of cleaning operations in the zones of reference (increased) rock pressure while maintaining the cut-off workings ahead of the lavas, the intensity of stresses and deformations and the duration of downtime of long cleaning faces sharply increases. The associated production losses reach 20-25% or more, the ash content of coal and the danger of miners' labor increases. Studies of the patterns and features of deformation of the rock mass, around the contour of the supported prisechny mine workings on the ventilation horizon when excavating the worked column below the previously worked one with the establishment of reliable fastening parameters, are important.
