Influence of some parameters of drilling and blasting on the pace of construction of groove have been investigated. The estimate of influence extent of the coefficient of efficiency of explosive, blast hole fill factor and structure of the rocks on the rate of penetration was made. Research has been done on the example of construction with the help of blasting technology in normal shaft of cross-sectional area 28,3 m2 with the use of concrete lining. Dependences of deepening speed from the structure of rocks, efficiency of explosives, mining hole fill factor have been defined.
