    Exploring Underground Water Passageways to Analyze Ground Safety For a Village Next to a Coal Pit Slopes in Turkey
    (PORTUGUESE SOC OCCUPATIONAL SAFETY & HYGIENE, 2015) Gokay, M. K.; Dogan, K.
    Electrical resistivity survey was performed to determine underground water passageways at an open pit coal mine in west Anatolia in Turkey. The mine has 7 benches with 10 meter bench height. Safety inspection for pit slopes which have dip directions towards Southwest is the main concern described here. Northeast site of the coal pit which has mainly marl, volcanic and clay layers. The main problem in this pit is the danger of slope failure after heavy rains. Electrical resistivity surveys therefore were performed at the Northeast border of the pit. Wenner alpha and Pole-pole methods were used to obtain earth resistivity data through multi-electrode surveying. After evaluating the field measurements, it was determined that there are more than 4 water passageways into the coal mine from Northeast direction.

    INTERACTION MATRIX APPLICATION AT ERMENEK (KARAMAN) LIGNITE MINE
    (INT SCIENTIFIC CONFERENCE SGEM, 2008) Gokay, M. K.; Erdogan, H.; Dogan, K.
    This study includes the application of interaction matrix system given by Hudson in 1992 to underground coal mining conditions. Implication of interaction matrix was realized here at private company owned underground coal mine. After clear description of the interaction matrix and its properties, selected mine workers and engineers worked at the studied underground mine were asked to evaluate predefined 21 evaluation parameters. During the evaluation of the matrix, the parameters were evaluated to obtain critical and dominant factors to rise the mine's operation efficiency. The interaction matrix form obtained from each person in this work were analyzed accordingly and saved for further inspections. These matrixes demonstrated which parameter was important and which one was dominant according to the person who evaluated the matrix.
