放顶煤开采覆岩破坏高度的统计分析

Statistical Analysis on The Overlying Strata Failure Height in Condition of Top-coal Caving

由于采场覆岩破坏高度及破坏程度是上行开采研究的最重要内容,因此,在对我国放顶煤开采典型覆岩工程地质条件分析的基础上,本文对放顶煤开采覆岩破坏高度进行现场实测统计分析,找出放顶煤开采覆岩破坏高度受地质因素的影响规律,从而为放顶煤条件下上行开采研究提供科学依据。

Since failure height and destruction degree of the overlying strata in working face are the most research contents to ascending mining. Based on analyzing on typical overburden engineering geological conditions in top-coal caving, field measurement and statistical analysis on the overlying strata failure height in condition of top-coal caving is carried out in this paper. To find the influence law which geological factors influence on overlying strata failure height in condition of top-coal caving. Therefore, scientific basis is provided for ascending mining study in condition of top-coal caving.
