Original paper


The traditional method for calculating the loose chamber pressure of shallow buried soil does not consider the special overburden structure of shallow buried depth, Bo Jiyan and thick unconsolidated coal seam, and even does not consider the activity law of overlying strata when the stope is under pressure. Based on the theory of elastoplastic and the theory of limit equilibrium theory, this paper presents a method to solve the loose pressure of overlying rock in shallow coal seam, the calculation method has a more rigorous mechanical basis, and the calculation results are more consistent with the actual situation, which effectively avoids the shortcomings of traditional calculation methods, and provides a new method for solving the loose pressure of overlying strata in shallow buried coal seam.
