The tracked vehicle 10 is used on road accessible land, which has terrain that allows unrestricted movement of such vehicIes.
[0003] For areas that are imaccessible or where environmental impact is of conoern, it is also known to use helicopter portable drilling systems. These drills are referred to as heli-portable drills. The method of uSing them is called heli-drilliug The earliest examples of heli-portable drills included three components: a drill, a compressor and a supplies basket, whioh must be separated due to weight limitations of various helicopters.
[0004] Referring to Fig. 2 there is illuWated a knowA drill from a three pick drilling system.
Typically the drills are hydraulically operated and have either a gasoline or diesel motor for powering the hydraulic pump. These pumps are used to operate the various hydraulic components of the drill. The driIl in Fig. 2 is from a two pick system but is atypical to a 3 piclc.

[0005] The seeond component is the compressor system an example of which is shown in Fig. 3.
The compressor has a diesel or gasoline engine that is used to operate a high-volume air compressor. A hose is used to connect the compressor to the drill. The air is used to operate an air hammer, which is down the hole. Once the air has left the hanmzer, it cleans out the drill hole by forcing the driil cuttings to the surface. Depending on the drilling eonditions, the driller may chose to drill with an auger style bit rather than an air hammer. In this case the air is only used to clean out the hole.

Depending on the drilling eonditions, the driller may chose to drill with an auger style bit rather than an air hammer. In this case the air is only used to clean out the hole.
[0006] The third pick typically contains drill stem, an explosive magazine, a cap magazine, drill mud, md aay other supplies that the driller deems necessary (not shown in the figures).
[0007] As technology continued to im.pro've all of the components that were typically in the third basket where moved to the drill and compressor picks. This was prixnarily due to improved helicopter perfonnance. Reducing the number of picks required not only reduces the time that the helicopter spends in a dangerous hover condition, it also significantly reduces costs due to less equipment being moved by the helicopter.
[0008] A complete drill crew generally consists of six drills, six compressors and various accessory baskets. There are several reasons that the crew consists of six units. The first is that each drill bas a driller and a driller's helper for a total of 12 persons. The Bell 212, 210 and 205 series of helicopters are configured to have a pilot, copilot and thirteen passengers. Six drills also give the helicopter adequate work each day, while keeping the drills productive. It is referred to as a cycle every time all of the drills are moved. The logistics of each program varies.
It is primarily dependent on terrain. A drill crew typically works oii between one and three seismic lines.

[0009] Refening to Fig. 4 there is graphically illustrated a typical seismic program having about 9000 shot points to drill with heli-portable drills.
[0010] Referring to Fig. 5 there is graphically illustrated a typical shot hole drilling sequence for a two-pick heli-portable drill system. Helicopter moves 20 drill from completed shot point A to next shot point to drill B. Then the Helicopter returns 22 to A to pick up the compressor. The helicopter moves 24 the compressor to B. The helicopter then flies 26 to C to start the sequence again for a second drill, e.g. moving to shot point B- E is not on diagram but was meant to be included to show 3 drills working on a single line. Depending on terrain, weather and drilling conditions there can be 2 to 6 drills worldng on a single line and multiple drill crews on a single program.

"rhe pilot and driller are both at risk when the drill is being picked or dropped. Every time the helicopter is in a hover position while worlcing over the source pont the pilot is worlcing in what is referred to as the dead xnan's curve. It is called this because if the helicopter has a mechanical failure, the height and altitude are not conducive to a safe landing, even on level grouncL
Typically not only is the ground uneven, but there are trees further endangering the pilot.
[00131 For the driller on the ground, it is equally dangerous, as they are worlang underneath a heavily loaded helicopter. Steep terrain, loose rocks and trees are also a hazard. The rotor wash from the helicopter is capable of lcmoaking down trees and blowing off loose limbs. When placing drills and compressoxs in steep terrain, the heticopter may have to spend extra time to ensure the unit is secure. The risk for both the pilot and driller was signiEcantly reduced twelve years ago when the two-pick system was developed. Two pick drills were developed around 1995.
Summary of the Invention [0014] An object of the present invention is to provide method and system for helicopter portable drilling.
[0015] Iti accordance with an aspect of the present invention there is provided a system for helicopter portable drilling comprising: a drili frame, a drill mast affixed a first end of the drill frame, a drill operatively coupled to the drill mast and operable using one of compressed air, pressurized hydraulic fluid and both compressed air and pressurized hydraulic fluid and a unified power source for providing compressed air and pressurized hydraulic fluid coupled to the drill, the total operating weight of the system being approxunately 3000 pounds for allowing a single-pick move by a helicopter.
[0016] In accordance with another aspect of the present invention there is provided a method of seismic line drilling comprising the steps of placing a first single-pick drilling system at a first location with a single pick, placing a second single-pick drilling systecn at a seoond location with a single pick, when fin.ished drilling, moving the 'first single-pick drilling system to a third loeation with a single pick, when finish.ed drilling, moving the second single-pick drilling system to a fourth location with a single pick. Once again depending on terrain, weather and drilling conditions there can be two to six drills worloing on a single line and multiple drill crews on a single program. The entire methodology of drilling will likely change due to the reduced number of picks. A crew will likely consist of between 9 and 12 drills instead of the traditional six [00171 In accordance with a fiwther aspect of the present invention there is provided a method of seismic line drilling comprising the steps of placing a first drill carrier at a first location with a single pick, placing a first single-pick drilling system on the c.arrier at the first location with a single pick, when finished drilling, moving the first single-pick drillin.g system to a second location using the carrier and when meeting an obstacle between drilling locations, moving the first single-pick drilling system to a third location with a single pick, moving the first drill carrier at the third location with a single pick and placing the frst single-piek drilling system on the can:ier at the third location.
[0018] In an embodiment of the present invention there is a drill carrier for moving the drilling system between locations when the terrain pertnits.

DetaRed Description of the Freferred Embodiment [0020] Referring tQ Fig, 6 there is illustrated in a right side view a single pick drilling system in accordance with an embodiment of the present invention. The single-pick drilling system 100 includes a drill frame 102, a drill mast 104, a combined power source, eompressor and hydraulic pump 106. The single-piek drilling system 100 also includes a fuel tank 108, hydraulic tank 110 (110 not seen in drawing 100, a detonator magazine 112, an explosives magazine 114, loading poles 116, drill stems 118 and air and oil separator 120. The drill frame 102 stands on four adjustable legs 122.
[0021] Reerrimg to Fig. 7 there is illustrated in a right front perspective view the single-pick system of Fig. 6. Fig. 7 shows the driller's station 124 with hydraulic and pneumatic controls.
Hydraulic tan]c I 10 is in bottom right corner under drill stem 118.
(0022] lteferring to Fig. 8 there is illustrated in a left side view the embodiment of Fig. 6. Fig. 8 shows the detonator magazine 112, the explosives magazine 114 loading poles 116 and the drill stem, all visible from the left side. Hydraulic tank 110 is under drill stem.
100231 Referring to Fig. 9 there is illustrated in a perspective view a combined motor turbine, hydraulic pump (mpItiple pumps may be used, piggybacked together in some configurations) and compressor for the embodiment of Fig. 6. The gas turbine 130 drives the hydraulic pump 132 and compressor 134 through primary and secondary reductions gears 136. The combined clutch and gearbox assembly allow all of the components from a two pick system to be combined into a single unit. This configuration is still able to utilize the same helicopters in use with the two pick heli-drills.
[0024] An exemplary implementation of the single-pick system follow:
Key components 1. Modified Single Stage Centrifugal Turbine and primary reduction gearbox. Custom automatic start and shutdown sequence electronics.
a. The primary reduction gearbox will reduce the turbine output RPM from approximately 60,000 RPM to one of the followiag 6000 RFM, 6480 RPM or 8640 RPM depending on the configuration required.
2. CuStom Gearbox, which con.sists of the following;
a. Manually engaged clutch (now configured as dual hydraulically engaged independent clutches) x. Emergeney stop which diseonnects both clutches and shuts down turbine.
b. Secondary reduction gearing that will reduce the primary reduction gearbox RPM to between 2500 and 2800 RPM depending on the configuration requirements. Gearbox configured with one output shaft between 6000 and 6480 RPM and a second output between 2500 and 2800 RPM. Both clutches can be engaged /
disengaged independently. Although the initial prototype will have a secondary gearbox I am ultimately worldng towards a single gearbox to further eliminate weight o. The secondary reduo'hon gearbox will have dusl output shafts. The primary si'laft will be used for the compressor 6480 - 6000 RPM (manufacture and model may vary depending on program conditions), while the secondary slaaft will be for operating the hydraulic pump 2500 - 2800 RPM (manufacture and model may vary depending on prograin conditions) 3. Helicopter portable tracked earrier for the heli-drill. This unit can be configured to either ride on or walk bohind with remote controls.
The turbine and gearboxes are all housed in a protective box to reduce the likely hood of damage. The enclosure is also desigaed as a protective housing in ease of rmechanioal failure (protect personnel azid explosives from flying debris. The enclosure will also house an air filter system for the gas turbine.
The exhaust system will have at least one cold air intake to reduce exhaust gas teraperatures. The exhaust pipe diameter witl also be increased in diameter to reduce the pressure of exhaust gases.
The remaining drill components vary depending on end user and the specific requirements that they have. The following may also be available to further reduce the overall mass of the drill.
1. Composite drill mast 2. Composite drill frame 3. Low mass air/oil segarator 4. Low mass fuel tank 5. Low mass hydraulic tank [0025] The complete drill configuration may inalude;
Dri71 Configaration The drill has everything that is currently on the two separate drill components. Here is a list that includes the majority of items required. The items on the drill are not limited to this list; this is a basic configuraticm of the key elements.
1, Compressor, air oil separator and compressor oil cooler 2. Detonator magazine 3. Drill fratne and rnast 4. Drill stem (both auger and smooth - as per drillers requirements) 5. Drj)IerS mud 6. Drillers station (with hydraulic and air controls) 7. Emergency shutdown system 8. Explosive magazine 9. Fuel tank 10. Hydraulic tank and hydraulic oil cooler 11. Power source for compressor and hydraulic systems (turbine and gearbox) 12. Required hydraulic pumps and motors for the drill (as per end user requirements) 13. Rotary pull down (either 4 hydraulic cylinder or hydraulic motor) 14. Toolbox 15. Water pump Carrier couGguratiion The carrier is a self-propelled track carrier that is capable of hauling the single pick drill. On occasion it maybe impractical to utilize the carrier due to the nature of terrain that the drills work in. The driller and drill coordiuator will decide on which areas the carrier is uSed in.
[0026] Referring to Fig. 10 there is graphically illustrated a method of heli,drilling in accordance with another embodiment of the present invention. Fig. 10 illustrates one of many possible variations with a single~pick drill. With the system of Fig. 6, only a single trip is required to move the drill betweeen shot holes. Fig. 10 shows how three single-pick drills 200, 202, and 204 could be moved. A helicopter moves 206 drill 200 from completed shot point A
to drill next shot point B. The helicopter then flies 208 from B to move the next dril1202 from completed shot point C to next Shot point D to be drilled 210. The helicopter thcn flies 212 from X) to move the next dril1204 from complete shot point B.
100271 Referring to Fig. 11 there is illustrated a tracked carxier for use with the one-picdc drilling system of Fig. 6 in accordance with a fiirther embodiment of the present invention. The tracked carrier 220 includes a platform 222 for receiving the single-pick drill system of Fig. 6 and a bulkhead 224. The tracked carrier of Fig. 11 has tracks 226 for moving across a variety of terrains and includes and optionally includes an operator's position 230 with a seat 232, controls 234 and rollover protection systeqa (ROPS) 236. Anoth.er configuration of tracked carrier 220 dispenses with operator position 230 and instead uses a remote control so that the operator can walk a safe distance from the tracked caaier. The heli-carrier will eliminate the need for the helicopter from shot point to shot point when the terrain allows. The heli-carrier is a lightweight self propelled track carrier that is configured to move or be flown to a shot point with a heli-dri11.
Once the carrier and drill are on site it is able to haul the drill to the next point.
[00281 Referring to Fig. 12 there is illustrated the one-pick drilling system of Fig. 6 carried on the tracked carrier of Fig. i l in accordance with a further embodiment of the present invention.
Fig, 12 shows the siugle-pick drill system of Fig, 6 placed on the tracked carrier 220 of f+ig. 11.
[0029] Referring to Fig. 13 there is graphieally illustrated a method of heti-drilling in accordance with another embodiment of the present invention. A drill 250 on a carrier 252 has completed drilling at shot position A. A helicopter moves 254 the 4rill to shot point B.
The helicopter flies back 256 to shot point A to retrieve the carrier 252. The helicopter moves 258 the carrier 252 to shot point B After traversing the obstacle (in Fig. 13 a river), the drill and carrier combination are able to move 260 from sliot point B to shot point C, to move 262 from shot point C to shot point D, to move 264 from shot point D to shot point E, when the terrain pennits such movement. Once a further obstacle is encountered, the helictipter repeats the process as from shot point A to shot point B.

100231 Referring to Fig. 9 there is illustrated in a perspective view a combined motor turbine, hydraulic pump (mpItiple pumps may be used, piggybacked together in some configurations) and compressor for the embodiment of Fig. 6. The gas turbine 130 drives the hydraulic pump 132 and compressor 134 through primary and secondary reductions gears 136. The combined clutch and gearbox assembly allow all of the components from a two pick system to be combined into a single unit. This configuration is still able to utilize the same helicopters in use with the two pick heli-drills.
[0024] An exemplary implementation of the single-pick system follow:
Key components 1. Modified Single Stage Centrifugal Turbine and primary reduction gearbox. Custom automatic start and shutdown sequence electronics.
a. The primary reduction gearbox will reduce the turbine output RPM from approximately 60,000 RPM to one of the followiag 6000 RFM, 6480 RPM or 8640 RPM depending on the configuration required.
2. CuStom Gearbox, which con.sists of the following;
a. Manually engaged clutch (now configured as dual hydraulically engaged independent clutches) x. Emergeney stop which diseonnects both clutches and shuts down turbine.
b. Secondary reduction gearing that will reduce the primary reduction gearbox RPM to between 2500 and 2800 RPM depending on the configuration requirements. Gearbox configured with one output shaft between 6000 and 6480 RPM and a second output between 2500 and 2800 RPM. Both clutches can be engaged /
disengaged independently. Although the initial prototype will have a secondary gearbox I am ultimately worldng towards a single gearbox to further eliminate weight o. The secondary reduo'hon gearbox will have dusl output shafts. The primary si'laft will be used for the compressor 6480 - 6000 RPM (manufacture and model may vary depending on program conditions), while the secondary slaaft will be for operating the hydraulic pump 2500 - 2800 RPM (manufacture and model may vary depending on prograin conditions) 3. Helicopter portable tracked earrier for the heli-drill. This unit can be configured to either ride on or walk bohind with remote controls.
The turbine and gearboxes are all housed in a protective box to reduce the likely hood of damage. The enclosure is also desigaed as a protective housing in ease of rmechanioal failure (protect personnel azid explosives from flying debris. The enclosure will also house an air filter system for the gas turbine.
The exhaust system will have at least one cold air intake to reduce exhaust gas teraperatures. The exhaust pipe diameter witl also be increased in diameter to reduce the pressure of exhaust gases.
The remaining drill components vary depending on end user and the specific requirements that they have. The following may also be available to further reduce the overall mass of the drill.
1. Composite drill mast 2. Composite drill frame 3. Low mass air/oil segarator 4. Low mass fuel tank 5. Low mass hydraulic tank [0025] The complete drill configuration may inalude;
Dri71 Configaration The drill has everything that is currently on the two separate drill components. Here is a list that includes the majority of items required. The items on the drill are not limited to this list; this is a basic configuraticm of the key elements.
1, Compressor, air oil separator and compressor oil cooler 2. Detonator magazine 3. Drill fratne and rnast 4. Drill stem (both auger and smooth - as per drillers requirements) 5. Drj)IerS mud 6. Drillers station (with hydraulic and air controls) 7. Emergency shutdown system 8. Explosive magazine 9. Fuel tank 10. Hydraulic tank and hydraulic oil cooler 11. Power source for compressor and hydraulic systems (turbine and gearbox) 12. Required hydraulic pumps and motors for the drill (as per end user requirements) 13. Rotary pull down (either 4 hydraulic cylinder or hydraulic motor) 14. Toolbox 15. Water pump Carrier couGguratiion The carrier is a self-propelled track carrier that is capable of hauling the single pick drill. On occasion it maybe impractical to utilize the carrier due to the nature of terrain that the drills work in. The driller and drill coordiuator will decide on which areas the carrier is uSed in.
[0026] Referring to Fig. 10 there is graphically illustrated a method of heli,drilling in accordance with another embodiment of the present invention. Fig. 10 illustrates one of many possible variations with a single~pick drill. With the system of Fig. 6, only a single trip is required to move the drill betweeen shot holes. Fig. 10 shows how three single-pick drills 200, 202, and 204 could be moved. A helicopter moves 206 drill 200 from completed shot point A
to drill next shot point B. The helicopter then flies 208 from B to move the next dril1202 from completed shot point C to next Shot point D to be drilled 210. The helicopter thcn flies 212 from X) to move the next dril1204 from complete shot point B.
