Abstract: System Analysis Approach has been applied in the present field based research paper for a deep and gassy coal mine of Jharia coal fields. The working panel was considered as a System, splitted into various sub-Systems. The Sub-Systems were statistically analyzed in terms of frequency distribution (after prolonged field observations). The Mean, Median, Mode, Standard deviation, Variance and co-efficient of variation were calculated. Among the Mean, Median and Mode, Mean was considered for Capacity (in terms of production) calculation of various Sub-systems
