Interchamber pillars partial working off technology at the floor-and-chamber system of development of the Korobkovsky deposit of KMA
- Authors:
- E. I. Boguslavskii
- M. N. Andreev
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.

Reducing losses ore between whole chamber for the design of lower layers mine by Gubkin of open joint-stock company «Industrial complex KMAruda»
- Authors:
- E. I. Boguslavskiy
- P. V. Korzhavykh
Technological decisions on decrease in losses of ore in between chamber walls are considered at designing of the bottom horizons of mine of Gubkin. It is offered two variants of decrease in losses of the ore technologically compatible with each other for their simultaneous use. Results of calculation of losses of ore and economic consequences are resulted. The basic actions which are necessary for carrying out, before introduction of technological decisions in manufacture are described.

Provision of safe coal mining with due account оf cleanup works at adjacent seams
- Authors:
- M. A. Ilyashov
During planning of mining works with coal series it is important to take into consideration mining conditions of each mine layer, to determine presence of natural and technogenic abnormal areas at its place and to appreciate their potential level of influence on the increase of rock pressure manifestations in the development and productive workings. In comparable conditions the most negative manifestations of rock pressure can be observed in roadways of neighboring low layer, when they are disposed in range of mutual action of abnormal areas of natural and technogenic origins.
