520			_a situ stresses have significant effects on the stability of openings, support requirements, parting stability, pillar strength, etc. In order to analyze the stability of underground structures, the measurement of magnitude and direction of horizontal stress is necessary in addition to knowing other geomining parameters and rock properties. In this direction, this paper presents a systematic determination of in situ stresses in three mines of the southern Raniganj coalfield of India, using single sleeve fracturing technique. Based on the analysis of field test results, the gradients of major, minor and average horizontal stresses are established for the southern Raniganj coalfield. The determined in situ stress values are used in numerical modeling for stability evaluation of known case histories of parting between contiguous seams and pillars of this coalfield. The numerical modeling results analyzed in this paper validated that the in situ stresses determined in the Raniganj coalfield are acceptable for the stability analysis of coal pillars, parting and underground roadways.
