New Jumbo and bolter use a similar system MILWAUKEE—(BUSINESS WIRE)—Komatsu is pleased to launch a new jumbo drill and bolter that utilizes a revolutionary common underground hard rock mining carrier and control device engineered to fulfill the needs of the industry for higher efficiency and flexibility thus helping lower capital costs. Our latest small-class ZJ21 jumbo drill and ZB21 bolter, built through comprehensive testing and cooperation with our customers, utilize a standard framework that enables operators to transform their system from a jumbo to a bolter, or vice versa. From the rear skirt to the outer boom frame, the platform provides 100 percent structural commonality between bolter and jumbo, allowing it a smooth conversion. The flexibility offered by the popular framework was designed to help mining operations understand job site productivity benefits and help minimize costs with the common components, service and maintenance. Furthermore, operator monitors are universal between the jumbo and the bolter, from a customer preparation and acceptance viewpoint, to support mining organizations. The ZJ21 jumbo drill is built to provide outstanding coverage, providing up to 66 square meters of face coverage on a tiny jumbo pad. When drilling somewhere on

the face, the special boom arrangement facilitates zero interaction with the operator's enclosure or the carrier or leveling jacks. The ZB21 bolter allows it easier for operators to bolt in either direction and can accommodate up to an 8-foot bolt head. Using our integrated screen handler and revolutionary chemical injection device, operators may execute 100 percent of the bolting period from inside the enclosure, allowing mining operations to move towards zero harm. "Our latest drilling and bolting platform was specially built to solve the challenging problems encountered by our underground hard rock customers," said Doug Eamer, director of Komatsu Underground Drilling. "The ZJ21 and ZB21 are only the first two of 14 new versions expected, so you can look forward to seeing more from us in the immediate future." Both the ZJ21 jumbo and the ZB21 bolter diesel variant are eligible for order right now with a battery option expected to be rolled out next year.
