Abstract

Several geological and structural features occurring within the coal deposits pose roof problems in underground mines. A semi-quantitative approach to assess their influence is through geomechanics classifications. For this, the important parameters influencing roof stability, such as RQD, rock strength, weatherability, ground water and structural features are identified based on the field experience and they are represented in the classification. The rating values for the parameters can be determined by index tests. However, the role of structural features is subject to selective treatment. Classification of mine roof strata is made by giving importance to ratings for the five parameters. Based on the classifications, suitable roof support measures can be adopted. By refining and standardizing the method, roof conditions can also be forecast for the unexplored areas of the mine.
