综放工作面过断层技术实践

Practice on Technology of Fully-mechanized Caving Face Passing Through Fault

在复杂地质条件下,为了快速推过大断层,通过对2种过断层方案的分析,提出了工作面正常推进、断层处平推硬过方案,并使用各种措施保证施工期间安全,通过实践证明了快速推过断层各类措施的有效性,提高了采出率,缓解了采装衔接紧张局面。

When mining under complicated geological conditions,to quickly pass through large fault, based on the analysis of the two schemes,the plan was proposed,that is ＂the normal face forward, pushed through the fault at the horizontal pushing＂. Results of filed practice have proved the effectiveness of measures for passing through faults. Recovery ratio of the coal was improved,and the intensive mining situation in coal mine was relieved, too.
