Three parts of mine design: feasibility study, preliminary design and construction plan
The key of 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, etc.
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
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, working group requires different professional division and cooperation, including:
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 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 situation.
After collecting information, electrical power specialty comes up with feasibility program for electric
power system of 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 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 workshop, production problems. Basing on these data, mineral
dressing specialty comes up with a feasible solution for new or renovation and expansion mineral
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 writer is 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 competent department of Mine Design
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.
