Course detail

Mining and Preparation of Raw Materials (M)

FAST-BJ053Acad. year: 2018/2019

The specialized course includes the field of general mining issues, quarries, and the preparation of mineral raw materials for a wide application in building industry. In the first part the raw materials exploitation, the general rules for the plan preparation, development and mining of raw materials are discussed, including the disintegration of raw materials, the draft of blasts projecting and the proposal of raw materials transport. The part preparation of mineral raw materials includes the breaking of aggregates, classical and special preparation processes, rules for the raw materials preparation for the ceramic production. The theory of disintegration is presented together with the theory of classification. The chapter is concluded with the proposal of a disintegration line including the output and capacity calculations. The course of preparation is concluded by the theory of mixing (composition) of raw mixtures according to the classical and optimization principle. The subject doesn’t contain a part with lectures, the exercise contains a part with explanations, in rest time the practical calculations and project tasks are solved.

Learning outcomes of the course unit

Students after Successful completion of the course will be acknowledged with the history and modern development of mining of raw materials for industrial production in general, special emphasis is on the extraction and subsequent treatment of raw materials for construction. In particular, there are three directions, natural aggregates, crushed aggregates and raw materials for cement and lime production. Then there are the mining and basic treatment of ceramic raw materials and mining blocks for architectural use in construction sector. In the second part of the course, students become familiar with the adjustment of raw materials, especially crushing, grinding and screening materials. Based on this knowledge packed graduates are able to:
• Describe all the basic technology of extraction of raw materials used in construction
• To understand the possibilities of using blasting not only for mining but also in construction
• Understand the basic technical problems of mining and processing of raw materials before processing to construction products
• Describe the obligations of mining companies against the government bodies , concerned entities in the area of mining plants as well as opportunities and obligations associated with reclamation after mining and environmental protection at all.

Prerequisites

The student who signs up for the course should be able to work with the basic concepts of general geology petrography, and mineralogy, possibly rock mechanics.

Co-requisites

During the teaching of the course, the student will necessarily continue to apply their knowledge of chemistry, physics and science of construction materials.

Planned learning activities and teaching methods

The content of the lectures is prepared in the digital form of presentations with the largest share of graphic details that will allow to closer understanding the objective issue. The content of exercise lectures is based on the digital presentation of task, which is then clearly undertaken by experiment and then student must compile and evaluate the results in the reports.

Assesment methods and criteria linked to learning outcomes

At the seminars students work up partial computational protocols. Attendance at seminars is compulsory, minimum attendance rate is 90%. During the exercise students work out protocols, protocols will be made by individually. To pass the final test is required min. 65% success rate. The course ends with an examination which is composed of compulsory written and oral part. To proceed to the oral is necessary to obtain at least 15 points (max 25) to pass the exam then at least another 10 in the ora
