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.

A set of problems is considered for planning underground mining of ore deposits. Achievements are noted in domestic mining
science in the field of improving planning methods and design parameters for underground mines. Principles in the development
of planning theory for mining enterprises at the contemporary level are formulated.

A study is performed into alternative methods of mixed geotechnology application to large-scale mining of different-grade
ores at thick deposits. The efficiency of using various combinations of physical and technical procedures for comprehensive
development of the Earth’s interior is demonstrated.

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 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.

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

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.
