Interchamber pillars partial working off technology at the floor-and-chamber system of development of the korobkovsky deposit of KMA

Article is devoted to a choice of rational technology of mining of part of stocks interchamber pillars at floor-and-chamber system of development of the Korobkovsky deposit of KMA. Authors carried out calculations and comparison of technical and economic parameters of two offered technologies of mining: horizontal layers with a stowing in an ascending order with application of a portable equipment and horizontal layers with a stowing in an ascending order with a driving of autobiases in interpanel pillars. For a choice of method of development for mining of part of interchamber pillar and determination of its parameters and indicators.

Physical modeling of interchamber pillars fixity in Gubkin mine

Procedure of Korobkovsky iron-ore deposit new levels mining with the usage of physical modeling has been determined. Evaluation of interchamber pillars fixity in Gubkin mine and soil surface deformation in the process of lift mining and fractional interchamber pillars robbing on three levels has been carried out. After conducting geomechanical research the decision of foremost development and mining of bottom level reserve between –125 m / –250 m has been made.

Economic efficiency reducing ore losses in pillars of level-chamber method operational at the Korobkovsky of the iron-ore deposit

Technological solutions of ore loss reduction in interchamber pillars at bottom levels design of Gubkin mine are developed. For the purpose of justification of these offers has been carried out: physical (with the use of equivalent materials) and mathematical (finite element method) modeling. The research results and schedules of economic borders of use of new technologies are presented. The requirement for pilot work before industrial scale use is established.

Development of geothermal resources – higher efficiency in utilization of the earth’s interior

Preservation of Russia as the great state, its further development and prosperity, appreciably depends on possibilities to provide its own power needs, and also fuel and electric power export. On this historical period, power resources are the basic trading source of replenishment of the state budget. However, oil resources, at preservation of volumes of its export, are quickly exhausted; natural gas is not boundless too. Coal stocks have essentially decreased with disintegration of the USSR, and the remained demand considerable investments, increase of current expenses and are characterised by decrease in quality of coals. Additional expenses on ecological protection of environment will increase. Search of alternative to the organic fuel, burnt in heating plants, is conducted more than ten years. Use of low-temperature sources of thermal energy of resources is one of general directions in the decision of this problem in the XXI-st century. It proves to be true: certain advantages of geothermal resources, a readiness of scientific bases of their development, world industrial experience and specificity of systems of a heat supply in the country.
