巷道式充填法回采进路充填体沉积特征及强度分布规律研究

STUDY ON SEDIMENTATION CHARACTERISTICS AND STRENGTH DISTRIBUTION OF FILL IN DRIFT CUT AND FILL MINING

通过模型试验和充填体实测，研究进路充填时充填料溢流脱水情况、充填料的沉积特征、充填体的水泥含量及强度分布特征，并对充填体的整体工程特征进行评价，提出了充填工艺的改进措施。

Laboratory model tests and field survey examination on the characteristics of dewatering,sedimentation,cement content and strength distribution of filling material have been carried out.An approach to evaluate the engineering characteristics of filling mass and a way to improve the process of filling operation are presented.
