The methodic of the field observation for the processes of deep benchmark displacements and configuration of the local observing station is offered. The analysis of the results of the field observations for the displacements of the ore pillar is accomplished, the isolines of settling and the isolines of the average speed of settling of the ore massif is offered.
According to geological data received on the Jakovlevsky deposit, the spatial geomechanical model has been developed. During the analysis of the is intense-deformed condition pictures of distribution of horizontal pressure and vertical displacement on border ore потолочины and карбоновой thicknesses have been received. It is established that the zone of clearing works essentially influences distribution of pressure and movings to border ore roof and carbonic thicknesses. By results of modeling it is possible to estimate possibility of formation of vertical water spending cracks in an ore roof.
The estimation technique прочностных properties peschano-cement закладочного a file applied on Jakovlevsky mine is developed. The technique represents the complex of mechanical tests including nondestructive control over durability of exposures of a file by an ultrasonic method and express definition прочностных of properties закладочного of a material by results of splitting of samples of any form.
