1 Atlas Copco Blasthole T4BH series Drills DTH and Rotary drilling Multi pass Holediameter 5 %in 97/8 in ( mm) Maximum hole depth for 25 ft tower: 147 ft (45 m) Maximum hole depth for 30 ft tower: 177ft (54 m) L

2 Combining high mobility with power and productivity The T4BH is designed for multipass, high pressure, DTH drilling The rugged and reliable T4BH features a 25 ft (76 m) tower and can drill a 2216" (68 m) clean hole in a single pass, while multipass drilling can reach to a total depth of 14716" (45 m) through a 5 rod carousel TheAtIas copco T4BH is synonymous with mobility, power, performance, and productivity Mounted on a custom carrier, the T4BH is designed to perform in rough terrain and has been the leading blasthole drill in its class in the quarry and mining industries for over 35 years The T4BH is a truck mounted, hydraulic tophead drive, specifically designed for DTH high pressure blasthole drilling An optional 30 ft (91m) tower is also available with the 8 x 4 carrier option Tower and feed system Raising the tower with a full complement of up to five 25 ft (76 m) drill pipes in the carousel can be accomplished in less than one minute The tower is raised and lowered by two hydraulic cylinders Tower pinning, pipe changing and drilling are performed remotely from within the operator's cab The feed system is powered by two hydraulic feed cylinders that raise and lower the rotary head smoothly and positively by way of heavy duty feed chain for pulldown and pullback The highspeed feed functions increase drilling efficiency and give the operators faster drill feed rates Standard rotation'on the T4BH is supplied by a hydraulic rotary tophead The rotary head is mounted to the feed chains by way of a mounting plate and two pins on both sides of the head, allowing the head to "float" This helps to prevent thread wear or damage during joint make up Rotary or DTHdrilling The T4BH is designed to handle 4" (102 mm) to 7 (178 mm) drill pipes and can be used for DTHor rotary drilling of holes with diameters from 5 %" (143 mm) up to 9 ~ (251 mm) Three different high pressure compressors can be provided for the T4BH, ranging from 900 cfm up to 1,250 cfm The "onoff" regulation system of the high pressure compressor can remove load during nondrilling operations This extends compressor life, saves energy and provides an easier startup With a weight on bit force of up to 30,000 Ibf (133 kn),the reliable T4BH is well matched for rotary drilling as well Compressor range HighpressureDTH HighpressureDTH HighpressureDTH 900efm@350psi/254m3/min@24bar 1,070efm@35Opsi/303 m3/min@24bar 1250efm@35Opsi/354m3/min@24bar,,1 l '"'~ ' :';J'

3 Operator comfort All operational functions are controlled from the driller's console within the cab of the T4BH The operator has an excellent visibility with an unobstructed view of the drill table The cab is thermally insulated, soundattenuated, heated, ventilated and is equipped with tinted safety glass, kick plates, an adjustable swivel seat, and two lockable doors A sixlight halogen night lighting system is provided as standard for operator visibility under low light operating conditions External 70watt halogen lights illuminate each of the following components: Power pack, tower and drill table Heavy duty concept The T4BH inline drive train consists of a diesel engine directly coupled to a compressor on one end and a hydraulic pump drive on the other This configuration maximizes mechanical efficiency The T4BH is built with a "floating" engine sub base which aids in isolation of the engine and mainframe from shock loads, while also maintaining optimal engine alignment A heavyduty engine silencer/muffler is also provided to reduce power pack noise emission Separate air inlet cleaners are standard for both engine and air compressor intake Coolers for the hydraulic oil, compressor oil, and diesel engine coolant are provided All coolers are mounted side by side in one package and each section can be individually removed for easy maintenance The T4BH utilizes a custom built, 3axle carrier designed to Atlas Copco specifications The rigid 16 in "H" beam frame provides a solid base to handle tough blasthole drilling conditions Efficient drill pipe handling The carousel drill pipe changer is part of the tower assembly and is located on the outside of the tower frame The tower is raised and lowered by two hydraulic cylinders Tower pinning and pipe changing is performed remotely from within the operator's cab Breaking pipe joints are done by a hydraulic positioned sliding fork wrench with limited impact, that minimizes shock loads on the tower, carousel, rotary head and feed components Hydraulic cylinders swing the carousel into and out from the loading position under the rotary head A hydraulic cylinder and ratchet rotate the carousel to index the drill pipe under the rotary head for changing An exclusive "key lock" carousel design securely locks in the drill pipe at both the bottom and the top of the carousel to ensure maximum safety for drill pipe storage and changing An auxiliary hoist with a capacity of 2,500 Ibf (111 kn) is provided as standard for drill pipe and accessory handling i,~~ :S;!\~ EClu~pment I _: SPJ,fiJl1$,'ij1~JI insula~edsound,'ii(' ttfeim!i ~I:t ~, o Six qu % ogeii night ligh~ ' package I Oc'Restangulard1JSt bogd witlf s);irting '0 o;auxiliarthoist for drill pi~nd accessory handling I o Cooling package rated up to,\21i'f (52 C) ambient o o Heavyduty engine silencer/rvu6i~r Separate air intake filters for engine and air compressor o Power indexed carousel for five 4 Y in 00 x 25 ft pipe o Remote hydraulic fork chuck for drill pipe breakout o Hydraulically powered auxiliary chain wrench o 225gallon (852 I) fuel tank o 4SV210spur gear 2motorrotary tophead with 0 to 160RPM, and maximumtorque 6,000 Ibfoft o Three 48 in (1,219 mm) stroke leveling jacks o Custom designed 3axle carrier with wide flange Hbeam frame o Remote tower pinning o Backup alarm
