大采高综采技术的应用研究

Study on Application of Fully Mechanized Mining Technology with Large Mining Height

概括了国内外大采高综采技术的现状与未来趋势,深入探析了综采面矿压显现规律不同开采方式与不同采高条件下顶板破断特征、高工作阻力条件下上覆岩层的运动规律,解决了大采高技术在应用中存在的煤壁片帮控制、工作面端部围岩稳定性控制及综采设备稳定性等问题。

This paper summarizes the present situation and future trend of fully mechanized mining technology with large mining height at home and abroad,deeply explores and analyses the law of strata pressure appearing in fully mechanized mining face under different mining methods and conditions of different mining heights,the characteristics of roof breakage and the movement law of overlying strata under conditions of high working resistance,and solves the control of coal wall in the application of large mining height technology.The stability control of surrounding rock at the end of working face and the stability of fully mechanized mining equipment are also discussed.
