Monographs

Edition of a new series entitled “Scientific projects – the KOMAG Centre’s monographs” was initiated at the KOMAG Mining Mechanization Centre in 2003.

Presentation of significant problems referring to the scientific and research projects of the Centre is the series objective.

Titles given below are the result of research projects and grants realized at the KOMAG Centre and their objective is to present significant state-of-the-art design techniques and innovative technological solutions.

USE OF THE ENERGY RECUPERATION SYSTEM IN A DIESEL ENGINE OF THE MINING MACHINE

Jerzy Świder,
Mariusz Woszczyński

An increasing number of electric and electronic devices in vehicles improves the safety and comfort of users as well as imposes higher requirements to power supply systems. Moreover, the global shortage of fuel requires a development of hybrid and electric vehicles. Recovery of waste thermal energy and its conversion into electricity are the economic and environment friendly methods to supply power to vehicles.

TESTS OF ACOUSTIC FIELD IN CLOSED AREAS OF POWER PLANTS

Marek Pierchała

Power objects belong to strategic installations. Characteristics of tested objects make tests and acoustic analyses more difficult. Thus, it was necessary to verify and compare available methodologies in difficult testing conditions of power objects. Methodologies based on PN-IEC 1063:1996 Standard and PN-EN ISO 3744:1999 Standard, as well as on the measurement of normal component of sound intensity were analyzed. Acoustic measurements and numerical tests of acoustic field distribution in closed areas are the subject of this monograph. The tests were carried out for a typical power plant.

COMPUTER AIDED TOOLS FOR SHAPING OF COMPETENCIES OF UNDERGROUND TRANSPORT WORKERS IN COAL MINE

Łukasz Jaszczyk

A method of conducting training of coal mines' workers with use of ICT such as virtual reality, Augmented Reality and RFID is presented in this monograph entitled "Computer aided tools for shaping of competencies of underground transport workers in coal mine". The method is based on concept of mobile training facility. It allows conducting training with use of ICT in a training center, in machines manufacturer's facility, and at user's site. Due to use of modern ICT, increasing of trainees' involvement in training process and increasing of their capability to assimilate knowledge is possible. The developed method allows change in conducting of training.

ADVISORY SYSTEM SUPPORTING ROADHEADER OPERATOR

Józef Jonak
Joanna Rogala-Rojek

Development of roadways with use of roadheaders is the basic work in the mining industry, which opens coal seams for extraction. In the Polish mining industry over 92% of roadways is driven by the method of cutting with roadheaders. The suggestion of advisory system, supporting the operator in selection of operational parameters, which are optimal in the local mining condition, possible to be implemented in the roadheader, is presented.

USE OF AIR-AND-WATER AEROSOL IN CONTROL OF AIRBORNE DUST CONCENTRATION IN MINE AIR

Antoni KALUKIEWICZ
Piotr ROJEK

In the Polish mining industry we observe high rate of incidence of pneumoconiosis. In the last decade over 4500 cases of pneumoconiosis among the people working in mine underground were reported. Recent implementation of mining concentration in Polish mines has lead to reduction of number of dust sources, what enables concentration of dust control equipment only in few places instead of dozen or so points in the mine. However, such a technological approach promotes generation of increased amount of dust in a confined space of underground workings.

MONOGRAPH 36

Hydrochemical modelling as a part of assessment of usability of wastes from underground mining in road construction

Bożena Rakwic

Wastes from hard coal mining industry make the highest stream of industrial wastes produced in Poland. Geotechnical parameters confirm the possibility of using those wastes in road construction. Besides the act on wastes, which is under preparation, treats the wastes as by-product in coal mining process. Lack of guidelines, which enable making assessment of wastes usability, taking into account specific properties of wastes and their changes, in association with geotechnical, construction, exploitation and environmental conditions, is a limitation for a development of this economically rational and technically favourable method of using wastes.
