Planning
Geological investigation and mine / quarry development planning
consist mainly of the following activities related to cement raw materials (limestone, clay, siliceous
material, iron and gypsum), aggregate resources (gravel, sand, crushed stone, crushed sand), and
various kind of raw materials of ceramic industries.
- Geological investigation of raw materials (including boring, etc.)
- Basic design of mine / quarry development, crushing plant, ore beneficiation
plant and material transportation facilities
- Supervision of mine / quarry development work and construction work
- Operation trainings on mining / quarrying daily operation
In Japan, Taiheiyo Engineering provides consulting and engineering work related to geological
investigation of concrete aggregate (mainly limestone), construction of aggregate crushing plant and
redevelopment work of existing mines and quarries.
Business Description
Geological Investigation of Overseas Industrial Raw Material
Resources and Planning of Mine / Quarry Development
Taiheiyo Engineering has conducted many geological investigations of raw materials, planning
of mine / quarry development work for overseas cement plant projects. Taiheiyo Engineering has
accumulated extensive work experience for conducting reliable
geological investigation and planning of mine / quarry development to meet customer’s
requirement.
Design for quarry development and equipment supply with vertical
shaft system
Taiheiyo’s vertical shaft system is recognized around the world as an advanced technology
that can stably supply limestone ore even in steep mountainous areas.
In eastern mountainous area of Taiwan, Taiheiyo’s design has become the standard system for
the development of limestone quarries in the area. In addition, Taiheiyo’s Rock Handling
System consisting of "Finger Gate" (hydraulic switching
gate located at the bottom of the shaft) and "Roll Feeder" is a sturdy and reliable system.
This system has a long term track record.
Guidance on Mining / Quarrying Operations
Taiheiyo Engineering generally provides operational guidance training for newly established
overseas cement plants at the beginning of their operations. Also, same guidance training
shall be conducted at limestone mines and quarries.
Design of aggregate production plant
There are many aggregate plants which Taiheiyo Engineering has been involved in its
establishment both in Japan and overseas countries.
In Japan, Taiheiyo Engineering has been involved in the construction of new aggregate and
crushed sand plants as the main contractor.
Thanks to long term rich experience, Taiheiyo’s detailed design, construction and
supervision of aggregate and crushed sand plants are highly reputed by many clients.
Material Analysis
Various kinds of material , ranging from raw material,
industrial waste, municipal solid waste and sewage sludge to cement product collected in the field or
plant, are evaluated at the R/D Center, which boasts modern, sophisticated facilities and a staff of
experienced researchers.
These samples are tested to verify that they are suitable in quality and harmless to environment, to
determine optimum mixtures, and to choose the process that should be adopted to achieve the most
economical production.
The special procedures and know-how, like the microscopic ONO method developed by Taiheiyo, as well as
the long experience of R/D Center, ensure accurate, reliable results.
Feasibility Study
A project’s feasibility depends on raw material, site
selection, conceptual design, cost and markets. Starting with the geological investigation, Taiheiyo’s
experts can determine project feasibility based on their long-term experience and far and wide know-how
through detailed data and information.
They perform on-the-spot investigations and conduct extensive home office analysis. Accuracy of the data
is important for reliable results so Taiheiyo’s experts regularly update such information.
Thus the feasibility of project can be assessed precisely. Many cement plants constructed so far based
on Taiheiyo’s feasibility study have been enjoying successful operation results.
Conceptual Design (Quarries and Plants)
Selection of a mining method and technology for the quarry
and those for plant are based on studies of raw materials, markets and site conditions. Machinery and
equipment are selected, the plant layout is prepared and civil works are defined. Both investment cost
and production cost are estimated for financial analysis.
Taiheiyo performs all these engineering tasks in order to facilitate further detail design for final
evaluation.
Project Tender Preparation
Taiheiyo assists the client in preparing
a comprehensive tender document by compiling all of the information obtained by feasibility study and
conceptual basic design.
This tender document provides all the rules and instruction necessary for the tenderer to prepare
their proposal so as to include all the necessary work and to comply with technical and commercial
conditions. This will lead to easy evaluation and selection of qualified contractors.
