Blasting Test and Analysis of Stone Quarrying for Rock-fill Dam of Houziyan Hydropower Station
摘要
Abstract
Good gradation is required for the filling material of concrete face rock-fill dam in order to ensure good compaction and drainage.Taking the rock-fill material quarrying at Houziyan hydropower station on Dadu river as a research background,we summarize 6 groups of field blasting test in Selonggou quarry,and analyze the main fac-tors affecting the rock-fill material gradation based on different blasting designs and screening results.Research re-sults show that the gradation is affected by spacing between blasting holes,length of stem blocking,and unit con-sumption of detonator.Before large-scale stone quarrying,blasting tests should be conducted for each impact factor in order to determine the optimal blasting parameters.Through the field blasting tests,blasting scheme and parame-ters that can be used to get eligible rock-fill material are obtained,and the achievements in this research can be guidance and reference for similar projects.关键词
