Designing support unilateral rectangular interfase of horizontal developments

Article preview

The design procedure of loadings on arch support unilateral rectangular interfaces in an ore file of Jakovlevsky deposit КМА is offered. The settlement scheme corresponds rigid and plastic model of deformation of an ore file in a roof of interfaces. A major factor defining size of loading on overlappings of interfaces, emptiness in a roof after filling there are. Low efficiency of flat overlappings of interfaces on chamber frames and advantages of overlappings of interfaces by arches from profile SVP with horizontal couplers from арматурной steels of armature was revealed. Possibility of operative calculation of loadings and a choice of parametres of overlappings on conditions of durability and stability of bearing elements of support in ores of various types is proved.

Modeling of the volumetric stress-strain condition of the rock massive in the near mine which are crossing zone of weakening

Article preview

According to geological data which was received at the Yakovlevsky deposit, the volumetric model was developed. This model taking into consideration the driving of the mine through zone of weakening. During the analysis of the stress-strain condition near the mine the character of distribution and numerical results of tangential and longitudinal stresses have been revealed. The zone of weakening affects to the distribution of stresses and displacements around the mine. To select the parameters of the lining support it is necessary to take into consideration weakenings and contacts in the ore massive and the distance for these zones.

Mine observations on the condition of the fastenings of the horizontal excavations interfaces in weak ores

Article preview

Survey of 12 typical joints with different types of fastenings was carried out. The actual geometric dimensions of the interfaces and fastening space were measured, the zone of rock squeezing at the sides of the excavation was determined, the operational condition and deformation values of the fastening elements in the area of the excavation interface were assessed.

Деформирование рудного массива вокруг горных выработок

Article preview

Характер деформирования рыхлых и плотных железно-слюдковых мартитовых руд вокруг выработки с крепью КМП-А3 различен. В плотной руде процесс смещений характеризуется знакопеременными деформациями руды во времени и вглубь массива. Большая часть смещений реализуется через 10-80 сут. Размеры зоны деформаций рудного массива в лежачем боку (1,2-1,3)R пр , в кровле (1,0-1,1)R пр , в висячем боку (1,3-1,4)R пр . Приконтурная зона размером 0,8-1,5 м склонна к разрушению. Размеры зоны деформаций вмещающего рудного массива в лежачем боку (1,0-1,1)R пр и висячем боку (1,1-1,2)R пр , в кровле (1,1-1,2)R пр . Стабилизации смещений вмещающего рыхлого и плотного рудного массива не зафиксировано.
