Assessment of Risks Relevant to Underground Measurements for Coal Mining Production and Exploration

Abstract

In underground mining establishments and in all processes of underground coal mining from investigation activities to production activities, geodetic measurements and the plans, maps and profile information that are obtained after the survey are all needed. All geodetic works and transactions made for underground coal mines have major differences from other survey applications in terms of form and quality but have a longstanding history and are widely used in the field. The role of realized underground measurements is very important in opening underground mine galleries with certain directions and slopes and in preparing all kinds of maps and plans in underground mines. In addition, measurements must always be taken for application and calculations in underground mine galleries with the issues relevant to coal mine production safety. Moreover, relevant to underground coal mining, mine surveying activities are important for planning above-ground transportation service and road routes, for maintaining compliance with legal requirements relevant to underground mining and for defining mine subsidence effects of mine gallery gaps over the earth surface. Furthermore, mining, geological and geotechnical studies and surveying measurements have been extremely important for the safe and secure production of coal energy. In this study, for the application of underground coal mining measurement activities with great differences in many features compared to above-ground topographic measurements, potential failures and risks were systematically assessed thorough failure mode effect analysis and Pareto analysis.
