The distribution of coal reserves in the Russian Federation is considered, in terms of active or reserve status, their end
use, open-pit versus underground mining, and suitability for extraction. Coal production over the next twenty years is predicted,
and the corresponding stages in the development of open-pit and underground mining technologies are formulated.

The paper discusses the studies devoted to evolution of prospective mining technologies for deep thick strata of the Talnakhsky
and Oktyabrsky deposits. The mining-and-technical features of the deposits are considered. A strategic trend is pinpointed
towards technological upgrading with automation and robotization of geotechnological processes. The authors prove practicability
of concurrent mining of massive sulphide and impregnated ores. The generalized models of mining enterprises are examined,
and a concept of a mine of tomorrow is set forth as a system of scientific ideas, principles and priorities.

The profit expectations of treating the technogenic formations in mines of the West Siberia are assessed based on the analytical
studies. The innovative processing technologies will allow production of marketable concentrates, extraction of noble and
rare metals and manufacturing of fractioned ballast stone.
Technogenic formation is dumped wastes of previous mining enterprises, which contain sufficient raw material suitable for
the efficient commercial utilization and new production with the new technologies applied

The paper sets forth scientific foundations and organizational-technical environment offered by ISO 9000 standards that are
oriented to product quality management and, thus, product quality planning. The authors describe the results of coal product
quality planning with using the QFD methodology, present a model of coal quality control through the coal product life cycle and mining technologies. It is proposed
to evaluate the quality management efficiency by the coefficient of concordance between the product quality and consumer’s
demands.

Conclusion Traditional evaluation of the energy intensity of the technological processes of strip coal mining with respect to direct
energy consumption is not exhaustive, since energy expenditures for the production of required resources in accompanying branches
of industry, and the mining of fuel for the production of energy, the amount of which should be significantly higher than
the sum directly expended for the mining and creation of the facilities for its execution are not considered.
The proposed method for evaluation of the total energy intensity of technological processes is based on the link between basic
energy outlays and production of the required resources. Evaluation not only of their direct energy intensity, but also with
respect to individual forms of consumable resources is therefore critical to the analysis; this is the basis for a search
for means of lowering the energy intensity of production on the whole and the development of resource-saving technologies.

The authors analyzed various criteria that are used in different classifications of mining methods and systems. It is shown
that today’s complex geomechanical situation of mining at large depths and wide application of mobile machinery to mineral
exploitation has brought to nothing the erstwhile practical importance of many geotechnologies. The modern trend-based classification
of the underground ore mining methods is proposed.

Substantiation of the sequence for opencast mining of a series of flat and inclined strata using the mined-out space for internal dumps 总被引:1,自引:0,他引:1
The possibilities of using the mined-out space of opencasts for placing the overburden in internal dumps are studied. It is
established that on completion of mining flat and inclined strata there are free capacities in the mined-out space consisting
of 40–70% of its volume which are a resource for placing the overburden from other opencasts with substantiation of the sequence
of mining large deposits. A complex criterion is suggested that takes account of energy expenditures for mining a deposit
and the energy damage caused to the environment. A procedure is given for solving the problem and results are presented of
calculations for the Taldinsk and the Tomusinsk deposits.

A method is proposed for selecting a rational mining sequence with internal dumping for flat stratified deposits, using new
principles of the open-pit process-space formation and development. The main criteria for substantiating the mining sequence
are geometrical form and development direction of the open-pit space, structure of the working wall and transportation network,
internal dumping capacities and mining earthworks volumes.

The author analyzes industrial injuries and diseases in terms of iron-ore mining enterprises in Siberia. It is shown that
the harm to health is conditioned by the technology chosen for underground mining. To improve the safety of mining operations,
it is recommended to select the sublevel caving method with areal-frontal ore drawing and mobile mining machinery for thick
steep deposits.

The results are considered for the in situ testing of a new variant of chamber mining with roof caving by the chamber - pillar
scheme under complicated conditions at large depths. It is shown that the increased horizontal stresses in a rock mass promote
improvement of the undermined roof stability and give an opportunity to raise the volumes of chamber mining.

mining areas, involving a wide range of mining and technological factors, considering mineral properties, mineral occurrence
conditions and geographical advantages of a mineral deposit location. The model capabilities are exemplified by a comparison
of technological characteristics of coals, transportation and power supply infrastructure of the productive mining areas at
the Kuznetsk Coal Basin.

The East Singhbhum region is a highly mineralised zone, with extensive mining of copper, uranium, and other minerals. The
concentrations of certain metals (Fe, Mn, Zn, Pb, Cu, and Ni) were measured in 10 groundwater locations and eight surface
water locations for four seasons during 1 year around a proposed uranium mining area. The ranges of Fe, Mn, Zn, Pb, Cu, and
Ni in surface water were 0.08–1.21, 0.02–0.32, 0.02–3.48 mg/L, 0.84–14, 1.25–36, and 1.24–15 μg/L, respectively, while in
groundwater, the ranges were 0.06–5.3, 0.01–1.3, 0.02–8.2 mg/L, 1.4–28, 0.78–20, and 1.05–20 μg/L, respectively. Only Fe and
Mn were found to exceed India’s drinking water standards. The data have been used to calculate a metal pollution index (MPI).
The MPI of both groundwater (28) and surface water (10) is well below the index limit of 100, which suggest that neither is
generally contaminated with respect to these metals. 相似文献

New development of sets equipment technologies for coal mine long-wall face in China 总被引:1,自引:1,他引:0
Background of the development and achievement on sets equipment technologies for coal mine longwall face in China was reviewed
initially. On the theoretical side, a coupling model of hydraulic support and surrounding rock, support parameters optimization
and three-dimensional (3D) dynamic design method were presented. On the practical side, this paper outlined some of practical
issues and discussed some relative methods and technologies. In thin seam coal longwall mining, how to lower equipment height
is the first problem that should be solved. Roof pressure regularity, control of roof-fall and collapse, and hydraulic support
stability were investigated preferentially in 5∼7 m coal seam longwall mining. The application of equipment for longwall mining
with 5∼7 m cutting height in China was concluded. The characteristics of full-mechanized top coal caving for extra thick seam
coal were presented. The automation of top-caving hydraulic support and relevant equipment have achieved important breakthrough.
At the end of this paper, further development of China’s coal industry and longwall mining technologies and equipment were
prospected in brief. This paper gives readers a comprehensive understanding of China’s coal mine longwall face equipment technologies.
It will give help to other countries on its coal mining development. 相似文献
