大采高工作面矿压显现规律研究分析

Large Working Strata Behavior Regularity of Analysis

S8310工作面是阳煤一矿首个一次采全高的大采高工作面。工作面矿压显现特征、采场围岩控制技术研究、支架与围岩的作用关系、顶板结构特征和运移规律等因素,都对大采高工艺的推广和应用具有重要的指导意义。为了掌握S8310大采高综采工作面的矿压显现规律和特征,通过分析和研究该工作面的矿压、覆岩运动规律、煤(岩)应力状态和变形规律,为大采高综采面顶板的管理、大断面回采巷道支护的优化设计提供了重要的依据。

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.
