Khasipov I. А Development of methods of creation of artificial constructions for the keeping of the reuse mining

Research object: process of deformation of rock constructions erected with the use of limiting surfaces. A purpose of work is development of methods of guard of the repeatedly in-use extraction making on the basis of building of artificial rock constructions with the use of limiting surfaces. Methods of researches. For the decision of the put tasks the complex method of research, which plugs in itself an analysis and generalization of literary sources of the preparatory making devoted a guard behind a cleansing backwall, was utillized; laboratory researches on physical models; analytical researches of mathematical model of mechanism of forming of bearing strenght ability of rock construction. It is first set that at the change of relative diameter of supporting element (attitudes of diameter of supporting element toward power of layer) from 0,25 to 0,5 loading-deformation description of guard building remains permanent. Buy this mass of supporting element must not exceed 40 kg It is first set that durability of material of shell does not render substantial influence on forming of of bearing strenght ability of supporting element. So at the increase of durability of tissue shell on a break from 30 to 110 N/sm (in 3,7 time) decrease fo height of guard building diminishes on 3,5%. It is first set of process deformations of supporting element, consisting in that at a ladening into him a bearing kernel appears as a triangle. Within the limits of kernel of breed of supporting element test longitudinal deformations, and transversal deformations take a place due to a change on grounds, limiting a kernel. Drawn on the results of researches in recommendations on maintenance of windway on a mine the "Oktaybrskiy rydnik", and also to the guard of conveyer drift on the mine of "Dobropolskaya". Purview: mountain enterprises, scientific researches, educational process.
