摘要：

Rotary peiforators are the simplest, since according to the procedure used, only an M-r. rotation momentum is required to be done for a given speed of rotation of the borer, in the range of 300-1000 rpm. Their main advantages lie in: simple construction; possibility of actuation with electricity, pneumatic and hydraulic energy; in softer rocks greater perforation speeds are attained, compared to other perforators; less. dust and noise are generated during perforation. Their disadvantage lies in the relatively narrow range of application, depending on the rock hardness and abradibility. The light and medium ones are efficiently used in rocks f <= 6 hard, and the heavy ones, mounted on perforation installations, in rocks f <= 12 hard. The paper presents a hydraulic perforator designed for an electrical-hydraulic drill, intended to drill coal in Lupeni Mining Plant. This was designed so that the axial feed force transmitted to the column of rods should be as close as possible to the perforator shoe and the screw of the feed mechanism, the perforator coupling system in the column of rods should be interchangeable, and fluid supply for the detritus evacuation should be made in the perforator's back, and have an as simple construction as possible. The rotary hydraulic perforator is small sized l(460x230x285 mm) and light (50 kg).
