Study On The Strata Pressure Behavior Of Thin Coal Seam 56901 Mining Face In Niuerzhuang Coal Mine

Thin seam mining research is focused on the field of coal industry research, thin seam working conditions due to its Face, Roof Management complicated by pressure on mining and mining conditions are complicated. Therefore, the study of thin seam mining pressure principle and mining methods to provide effective technical support for the safe and efficient production of thin coal seam face.In this paper, cattle Coal Mine 56901 Face research background, theoretical analysis, similar simulation, field measurement and other methods to study thin seam mining face pressure apparent regularity, rock stress distribution characteristics of the overburden characteristics and movement laws and the like. By law 56901 mining face pressure field measurement and analysis of underground pressure law of face, bearing pressure distribution. Similar by laboratory simulation experiments, analysis work surface mine overburden pressure and stress distribution law, breaking the rock characteristics.By cattle Colliery 56901 Thin Seam Face research, study its geological conditions and underground pressure law, based on the analysis of thin coal seam and surrounding rock stress support theory, to ensure safe and efficient mine production, and exploitation for the Face a series of problems encountered in the process optimization program and propose solutions.
