An analysis is performed into the currently applied coal mining methods using mined-out space in an open pit, with describing
their basic advantages and disadvantages. The urgency of further development and wider application of the gritwise-and-capwise
methods that involve differently directed advance of a mining front and mined-out space utilized to the limit for overburden
storage is pointed out.

The authors offer the optional versions of mining methods and technological schemes for mining at Udachnaya pipe reserves
under the opencast bottom. The rational chamber-and-pillar method has been substantiated, considering the complicated mining-geological
and geomechanical condition at the deposit. The economical feasibility of the proposed underground mining variants has been
evaluated.

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 review of the domestic and foreign cost-estimate methods for the development of mineral deposit is performed. A new approach
has been proposed for the operational estimate of the reserves accessibility and costs of a deposit development. The results
are presented for the approval of the approach as applied to open-cast mining at copper-porphyritic deposits.

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

The paper expounds results gained in mathematical modeling of stress state of a rock mass under mining by sublevel caving
with areal-frontal and frontal ore drawing schemes. Stability of underground excavations in the course of applying the compared
methods is evaluated in terms of the Sheregesh deposit. The authors recommend on supporting the openings at the ore drawing-off
level.

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.

The authors offer new solutions for mineral mining. A key idea is the construction of artificial separating masses at the
stage of preparing a deposit and its part for exploitation. In terms of the underground mines belonging to “Alrosa“ JSC, “GMK
Norilsk Nickel“, it is shown that the implementation of the new approach will prevent mine workings from aggressive water
ingress, secure from other negative factors, and will allow the application of highly productive chamber mining schemes.

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.

Application of GPS in mining and geology has proved to be of ever increasing importance since recently. GPS is used for positioning
both researching and exploitation drill holes, mining facilities, equipment, machines, when monitoring slopes and falls, mining
facilities dimensioning, navigation of machines, roads tracing, etc. The paper presents a pilot system for surveillance and
monitoring of energetic and technological parameters at open pit mines, developed at the “Jazovnik” open pit mine for experimental
purposes.

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 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.

Using the former Luxembourg mining basin as a test site, the current research has been carried out to check whether or not
subsurface radon concentrations can be related to mining and mining subsidence voids in order to allow the creation of a subsidence
risk map. The location of enhanced radon concentrations may point to a local increased subsidence risk, consecutive to a fractioning
of the underground.
