摘要
Abstract
Currently, rock heading for the main practices Excavating, Excavating circulating footage determines the driving speed, therefore, the application of deep hole blasting in rock drifting increasingly widespread. Implementation of deep rock blasting technique is limited by the conditions in the hard rock tunnel, explosives consumed in large quantities, prone to"pump gun"phenomenon, borehole utilization rate for hole blasting hard rock scene in question, on the hard rock tunnel hole blasting technology research, by changing the way undercutting, blasting parameters, charging structure to improve the blasting effect. In this paper, coal Chensilou example, through ifeld tests of the technology in deep hole blasting hard rock launched a study.关键词
