Boring techniques and an introduction to mining technology

obligatory courses

The course covers the discussion of issues related to the methodology of execution of works for the purposes of geological drilling and exploitation. Presented technical characteristics and intended use of various types of drilling rigs and drilling technology, carry out works in various ways. Methodology of preparation of technical project of boreholes are also discussed. Part of the course is designed to present the general principles of mining preparatory works and supplies, as the primary method of obtaining minerals.

In the section on drilling lecture covers the following topics:

- Scope and possibilities of drilling and mining techniques in geological basic research, exploration and exploitation of mineral deposits, geological and engineering studies, research and exploitation of groundwater;

- Characteristics of drilling methods used in the diagnosis at the near surface geological research, reserve sites, hydrogeological and geological engineering;

- Manual drilling: tools, technology of drilling wells, sampling, failures, instrumentation;

- Drilling Hammer: patterns and principles of drilling rigs, equipment, technology of drilling wells, sampling, failures, instrumentation;

- Characteristics of the methods used for deep drilling exploration of geological and exploration hole;

- Drilling fluid - tasks, properties, measurement and correction of physical and chemical parameters;

- Rotary drilling, a small diameter: patterns and principles of drilling rigs, equipment, technology of drilling wells, sampling, failures, instrumentation;

- Rotary drilling, the normal diameter: tools, technology of drilling wells, sampling, failures, instrumentation;

- Characteristics of the methods used to perform the drilling water intakes;

- Rotary drilling, large diameter: equipment, technology of drilling wells, sampling, failures, instrumentation;

- Special works in boreholes - preparation of boreholes and execution geophysical surveys (well logs), closing in groundwater levels, special methods of sampling, the elimination of the holes;

- Geological drilling services - duties monitoring and supervision of geological, geological laboratory Geoservice type, scope and principles of geological documentation, profiling cores.

In the section on mining lecture covers the following topics:

- Principles of borehole exploitation of mineral: bitumen, salt, sulfur, thermal waters;

- Geological and mining conditions of use of the excavation pit operational characteristics of the excavation, operating systems, drainage pits, storage of overburden and waste rock mining;

- Types and purpose of underground mining - excavation and survey, providing, preparation, supplies, transportation, housing and liquidation of mining excavations selected space, ventilation and drainage of underground mines.

After learning the the messages to the lecture, the student:

- Recognize the different types of drilling rigs and equipment and drilling tools, their purpose and method of use;

- Determine the suitability of different types of drilling rigs and drilling technologies for solving geological;

- Sets depending on the geological conditions of tasks requirements and test specifications for the project execution of boreholes;

- Knows how to retrieve samples from drilling material and assess its suitability for further research;

- Perform the geological profile of the borehole;

- Monitors compliance with the performance downhole geological and technical design of the borehole;

- Settles formal and substantive implementation of the borehole.
