摘要:

摘 要:特殊地质赋存下顶板破断规律及压力分布的掌握对于煤炭开采过程液压支架的受力情况把握及支架选型具有非常重要的意义。基于UDEC软件对断层影响下采场顶板的破断规律进行了分析,研究了断层的不同带宽和产状对采场顶板最大下沉值和应力的影响规律,得到了不同断层分布影响下采场顶板的破断规律,这些将为断层影响下采区顶板的支护提供一定的理论指导。

Abstract:

Abstract: Study of the break law and the stress distribution of the roof has great significance in analysis of the force condition of the hydraulic supports, and the support selection. This study analyzes the break law of stope roof under the influence of faults, and the maximum subsidence and stress of stope roofs influenced by different widths and the shapes of faults, finally the break law of stope roofs under the influence of faults is obtained. The study which is based on UDEC software will provide theoretical foundation for supporting stope roof on the influence of faults.
