Abstract
In order to ensure the stability of roadways, Anglo American Metallurgical Coal (AAMC) has developed a roof support design methodology that integrates analytical, numerical and empirical modelling through an integrated design methodology. This methodology currently is based on a deterministic approach. However, an improved methodology, based on a stochastic modelling technique, has also been developed and is being evaluated for various roof support design practices. The main advantage of this methodology is that the final design is based on the probability distributions of input parameters, thus the outcome is based on a distribution of factors of safety. This methodology has been evaluated at AAMC operations for the designs of roof support in critical areas and offers and improved method for determining the roof support requirements. A demonstration of the application of this methodology for the design of install road roof support at Moranbah North Mine is presented in this paper.
