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
I Feasibility study
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 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 Verifiion Report" and the approved documents of qualified geological prospecting departments
Mining specialty Information collection1Opinion and requirements of clients of mine construction2For new mines collecting the existing layout maps of exploration engineering for technical improvement mines collecting the existing transit system information3Detailed knowledge of mining area terrain and surrounding environment conditions4Design 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 specifiions new mine required by collecting mine information of lifting transportation pressure drainage etc.
4 Civil engineering specialty Information collection1Investigation field geomorphic condition2Collecting hydrological data and "geotechnical engineering investigation report"3To know the local architectural style structure waterproof thermal insulation and other building practices4Investigation 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 collection1The electricity supply environment of mine 2Topography and geomorphology between ore area and current source3The basic condition of transformer substation4The requirements of local power supply department such as power power supply mode the starting mode of large electrical equipment 5The local requirements of lightning protection and grounding6The condition of external communiion and local communiion. For improvement and extension mine information collection1Mine power supply existing situation2The general situation of transformer substation3The setting situation of existing safety source 4Existing communiion 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 1500 11000 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 specifiion 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 Process 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 qualifiion 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"
II Preliminary design
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 communiion 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. whats 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 Institute
III Working drawings
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.
