Abstract
Drilling and blasting is one of the main driving methods in coal mine. medium-length hole blasting technology is an important research topic in drilling hole blasting. Whether to achieve the deep hole blasting, have a greater impact on the roadway excavation speed, safety, construction costs. At present, there are many constraints in theory and practice, the medium-length hole blasting technology have not been effective application and popularization in the coal mining enterprises. focuses based on cutting test more than 20 times the advantages and disadvantages were summed up in this paper.关键词
