摘要
工作面煤壁片帮问题制约了大采高综采技术在软煤层中的应用,软煤层中采用大采高综采技术能否成功的关键在于能否防止片帮现象的发生。文章以工程实例为基础,对片帮机理进行研究分析,运用力学理论对软煤层大采高综采工作面煤壁破坏的拉裂破坏和剪切滑移破坏进行了分析,提出了相应的预防措施,以此满足煤矿安全、高效生产要求。
Rib spalling has restricted the application of fully mechanized mining technology with large mining height in the soft coal seam. The key lies in whether the rib spalling could be prevented. The paper bases on an engineering example, studies the mechanism of rib spalling, analyzes the splitting destruction and shear slipping destruction with mechanics theory, and proposes corresponding precautions to meet the requirement of secure and efficient production.
