Abstract
At present, in excavation of the coal mine roadway, it is widely used to a full section of millisecond blasting in borehole depth of about 2.0m. A lot of practice shows that, due to the influence of geological conditions, drilling, charge and other factors, footage per cycle reaching 2.5 ~ 3.0m, there will be a large number of unexploded dynamite, or the low utilization rate of blasthole, which affects the driving efficiency. We need to research and develop a type of rapid composite drilling jumbo, which can drill auxiliary holes with diameter around 38mm, and can solve the drilling problem of large-diameter and center deep-hole of diameter not less than 120mm and hole depth of about 3m. It matches the key blasting technology of large-diameter parallel cut blasting method, which can improve the efficiency of drilling, blasting and driving excavation.
