大采高综采技术关键问题与对策探讨

Key Problems and Countermeasures of Large Mining Depth Fully Mechanized Technology

基于对国内外大采高综采技术的现状和发展趋势的分析,针对大采高综采技术在实际应用过程中存在的煤壁片帮控制、工作面端部围岩稳定性控制、大采高综采设备稳定性等关键问题,提出深入研究大采高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等,为大采高综采技术的改进提供了参考。

Based on the analysis of current status and trends of large mining depth fully mechanized technology at home and abroad, according to the problem of coal wall rib spalling control, the stability of surrounding rock control and equipment,mine pressure behavior, roof breakage characteristics under different mining and mining depth were deeply studied to provide reference for the improvement of large mining depth fully mechanized technology.
