利用陷落柱伴生断层预测陷落柱

Making use of associated fault to calculate caved pillar

阐述了陷落柱伴生断层在陷落柱周围的存在规律、性质及特征，并叙述了伴生断层带内煤岩层特征及与周围煤岩层的关系，这些特征均为陷落柱伴生断层所特有，易与其它断层区分。可以利用已揭露的该种断层对陷落柱进行预测预报。在现场工作中，正是利用伴生断层的这种特征，多次预测预报工作面前方的陷落柱，成功率在95％以上。文中仅举出了三个在掘进、回采工作面应用的实际例子。这种方法既简便，又易普及，效果好，适于生产现场推广应用。

Expounds property,characterize and existent law of assiociated fault around caved pillar,the characterize of coal seam, rock statum in the associated fault, the connection betwecn associated fault with enviroment. According to the characterize that we differentiate assoclated fault from common fault. Making use of exposed associated fault, we have calculated the caved pillar. The efficiency is 95%.
