摘要
依据北峙峪煤矿1511工作面地质条件,通过UDEC数值模拟软件和现场实测的方法对综采工作面遇断层时的老顶来压步距及超前支承压力影响范围进行分析研究,得到断层对综采工作面矿压显现规律的影响,并提出具体防治措施。
According to the geological condition of No.1511 working face of North Zhiyu Mine, numerical simulation software, UDEC, and field test were used to study the weighting intervals of main roof and advanced abutment pressure range when fully-mechanized working face passing fault. The study achieved the influence of fault on the strata behavior and proposed some specific countermeasures.
