Abstract: The objective of this project is to identify or to develop methods or procedures for the determination of the principal stresses in coal mine workings, which in turn would provide improved criteria for mine design layouts in coal mines. To address the objective a survey of 52 papers was carried out to identify methods which could be of use for the determination of in situ stresses in coal mines. This survey showed that the majority of methods used to measure stress in coal seam and then over-cored by a larger diameter hole which results in the stresses acting on the sensor being relaxed
