| Abstract: | On the base of their working experience over the years and in the light of the features of limestone mines,authors studies various factors of influencing the quality of blasting with medium length holes These factors are geological and mining conditions,drilling and blasting parameters,primer position,charging structure,blasting sequence,millisecond delay interval,explosive characteristics and others On the base of the above study,the technological measures for elimination or weakening of the unfavorable impact of these factors are put forward |
