[Abstract]:The research on thin coal seam mining is a key area of coal mining industry in our country. Because of its working face condition restriction, roof management is complex, the mining condition is complicated because of the influence of mine pressure. Therefore, the study of mine pressure law and mining method of thin coal seam provides an effective technical guarantee for safe and efficient production of thin coal seam face. This paper takes Niuerzhuang Coal Mine 56901 face as the research background, through theoretical analysis, laboratory similar simulation and other methods, and carries out the actual measurement of mine pressure in the working face field. The characteristics of mine pressure behavior and the law of roof and floor movement in 56901 working face are studied in this paper. The characteristics of overlying strata movement are studied. The stress of surrounding rock and the distribution of supporting pressure are measured at the site of the working face, and the pressure of the face is analyzed. In this paper, the rock pressure law, stress distribution and fracture characteristics of overlying strata on working face are analyzed by similar simulation experiment in laboratory. Based on the study of the 56901 thin coal seam face in Niuerzhuang Coal Mine, and on the basis of studying its geological conditions and rock pressure law, the paper analyzes the stress and support theory of surrounding rock in thin coal seam, so as to ensure the safe and efficient production of the mine. The optimization scheme and solution are put forward for a series of problems encountered in the mining process of working face.
