Three parts of mine design: feasibility study, preliminary design, and construction
The key to mine design is all must be established on the basis of detailed investigation, and
therefore Xinhai Mine Design Institute will firstly take a comprehensive field study to the mine of
clients including the crude ore for dressing plant, site, water, electricity, traffic, geography,
These investigation contents need the cooperation of geology, mining, ore dressing, smelting,
machinery, civil engineering, electric power and other departments.
In the feasibility study stage, first, Mine Design Institute and the client need to sign the
entrustment agreement. After the two sides reaching an agreement, Xinhai Mine Design Institute
starts to establish a working group for work including: planning, investigation, data collection,
planning and optimization, project evaluation, "report" writing, and exchanging views with
commissioned units to form a formal report.
In all the work of the working group to carry out, investigation, data collection and plan
optimization is the most important basis for selecting plant construction scheme. For these
important parts, the working group requires different professional division and cooperation,
1, Geological specialty ： Collecting "Geological General Survey and Design",
"Geological Survey (detailed survey) Report" or "Reserve Verification Report" and the approved
documents of qualified geological prospecting departments.
Mining specialty ： Information collection: (1), Opinion and requirements of clients
of mine construction (2), For new mines, collecting the existing layout maps of exploration
engineering; for technical improvement mines, collecting the existing transit system information
(3), Detailed knowledge of mining area terrain and surrounding environment conditions; (4), Design
information of the preliminary design stage of mine.
According to this collecting information, mining experts design or optimize the mining method,
equipment, ventilation system and so on, and come up with a feasible plan for mining section.
3, Mining machinery specialty ： Judging the situation of mine existing equipment
or equipment quantity and specifications new mine required by collecting mine information of
lifting, transportation, pressure, drainage, etc.
4, Civil engineering specialty ：Information collection (1), Investigation field
geomorphic condition (2), Collecting hydrological data and "geotechnical engineering investigation
report"; (3), To know the local architectural style, structure, waterproof, thermal insulation and
other building practices (4), Investigation of material sources, transportation and price of the
local building including gravel, brick, lumber, steel, cement, etc. Basing on these data, Civil
Engineering Department explains the form of building construction for customers in the report and
determines the main project structure and the main construction method.
5, Electric power specialty ： For new mine, information collection (1), The
electricity supply environment of mine (2), Topography and geomorphology between ore area and
current source (3), The basic condition of transformer substation (4), The requirements of local
power supply department, such as power, power supply mode, the starting mode of large electrical
equipment (5), The local requirements of lightning protection and grounding (6), The condition of
external communication and local communication. For improvement and extension mine, information
collection (1), Mine power supply existing situation (2), The general situation of transformer
substation (3), The setting situation of existing safety source (4), Existing communication
After collecting information, electrical power specialty comes up with feasibility program for
electric power system of a new mine or improvement & extension mine.
6, Mineral dressing specialty： Information collection for new mine: "Ore
beneficiability test report", plant topographic map (1:500 1:1000), the water, electricity, tailings
dam, environmental protection requirements, the construction standards, the amount of investment and
building an opinion of owners. Information collection for extension mine: the current project scale,
ore beneficiability test report, the present production process, operating parameters, material
consumption, existing specification and production capacity of equipment, general layout plans of
the existing processing plant, equipment layout plans of a workshop, production problems. Basing on
these data, mineral dressing specialty comes up with a feasible solution for new or renovation and
expansion mineral dressing plant.
In addition, the specialties needing to collecting information including general plan
transportation (geographic and topographic data; social economy; weather; flood;
engineering geology and hydrology geology; traffic; environmental protection),
tailings (tailings information, hydrometeor), drainage, HVAC, etc.
By the data collection and the feasibility study from the various specialties, Mine Design Institute
ultimately determines a feasible scheme for the plant construction and writes the "
feasibility study report " submitted to the relevant departments.
"Feasibility study report" with strict requirements on qualification, ability, experience,
professional title of a writer is an important basis for evaluation EIA and safety unit (some
projects must take soil and water conservation and land reclamation evaluation).
Clients would have a general understanding of the dressing plant scale, investment scale, profit and
other key factors by "Feasibility study report".
Cargo in bundle
After "Feasibility study report" approved, Mine Design Institute starts preliminary design and comes up
with the design of dressing plant construction. Design mainly involves dressing, general layout,
electric power, communication, civil engineering, environmental protection, water supply and drainage,
tailings, safety and fire protection, investment estimates, economic benefit. For the improvement and
extension enterprises, the preliminary design will illustrate the status, characteristics, plant, main
problems, utilization of main buildings and equipment.
Xinhai Mine Design Institute has many engineers who can design different types of dressing plants
(less investment, quick capital return or easy management) according to clients’
requirements. what's more, the design cost is lower than the national standard.
After the completion of the preliminary design, Design Institute experts will gather all content to form
the detailed “Preliminary design report " submitted to the competent department of
Mine Design Institute.
When the preliminary design is approved, Mine Design Institute starts to design working drawings. Every
aspect of dressing plant needs a lot of construction drawings (generally, over 100 working drawings),
such as civil construction. Engineers of Xinhai Mining Institute are numerous with rich experience and
drawing speed. When the working drawings completed, the designers must hand the drawings over to
construction commanding officers, especially, the notes, strict regulation and important content.
Xinhai Mine Design Institute is the first mineral processing design institute, with class A
design qualification of metallurgical industry, which can undertake the design business of
non-ferrous metals industry construction projects and support engineering without scale limitation.
Xinhai Mine Design Institute provides technical support for EPC, mainly responsible for the relevant
problems of mine design and mine consulting. Over the past 20 years, hundreds of Xinhai EPC are
completed successfully relying on the technical support of Mine Design Institute as.
