S8310 Yang coal face in a mine is the first full-time mining of large mining height face high. Face mine pressure behavior, the role of the relationship between stope surrounding rock control technology research, support and surrounding rock, roof structural characteristics and migration law and other factors, have an important guiding significance for the large mining promotion and application of high technology. In order to grasp the S8310 large fully mechanized mining face strata behavior regularity and characteristics, the analysis and research of underground pressure of the face, the movement of overlying rock, coal(rock)state of stress and deformation law for large fully mechanized mining roof management, optimization design large section of roadway support provides an important basis.
