8. Soil Sampling Kit • This tool is used to take soil samples with depth is limited, because the manual, usually done in addition sondir holes, so that the obtained correlation between the strength of soil types and land dikandungnya.

9. SOIL SAMPLING KIT

10. Equipment needed • 1. Rod Head 8. Saw tooth shoe • 2. Turning Rod 9. Retainer • 3. Rod 10. Pocket shoe • 4. Open spiral auger 11. Trap value • 5. Closed sprl auger 12. Profil drill • 6. Chisel drill 13. Pipe Wrench • 7. Iwan auger 14. Tube sample

11. HOW usage TOOLS • Clean the area to be on the bor • Place Iwan Auger / drill at the bar chisel drill • Press while playing, after filling up the sample, taken with caution • Remove the sample from the Iwan Auger didiskripsi for the type of soil and material dikandungnya, store in plastic / sample bag, labeled, contain information drill point number, depth, date, etc..

12. * Repeat procedures 3 and 4 to reach the planned depth * To get a sample of the original land use tubeundisturb The implementation of the sample and pressed enough just not playing. * After the original soil sample obtained in the tube, separated soketnya, clean tube and outsidepotonglah the cape setebal 1 cm for the liquid wax. * While the tube is cleaned, heat melt wax in order to close the tip-end of the tube is.

13. * Enter the label that contains no TTK drill, the depth, the top / bottom, etc. of the sample. * Original soil sample should be inserted into this tube protector, especially when the examination / laboratory is far enough from the drilling.

14. Sample blank Hand drill

15. PORTA SAMPLER • The tool is designed for samples of rock and shallow location may not be achieved with a large drill machine. • Called Porta sampler, from the word Portable, because the tool is easily carried to go-everywhere, lightweight, and practical. • Bekerjanya tool is the same as the drill tool another, namely the principle of press play • Can be operated alone, where the human lap, the power hydraulic pressure.

18. PORTA SAMPLER:The tool is usually taken to go and which is relatively lightweight, so it can be used in areas difficult to reach by machine drill

19. TOOLS • Double acting hydroulic ram tool is a tube in which there is a valve-regulator valve movement towards a kind of "kelly" is. • Tripot, 3 foot buffer to sustain hydraulic ram. • Hydraulic pump, the hydraulic oil, pedal and hydraulic hose connected to the ram hydrauloc

20. *Rod turnerHave the form of a special function to play kelly, so this tool seems to sit over kelly.*Chisel Auger generally spiral form can also be used "shalby tube / thin wall tube sampler"

22. BLAST HOLE DRILLING By : Drs.AGUNG WIDYATMOKO, M.Pd AGUS SUGIHARTO.ST.MT.

23. Blast Hole Drilling • Drilling holes to make the shoot / hole which later filled materials for diledakan. • Can be used for: Reservoir development The making of the tunnel The minerals in hard rock Dismantling road Dismantling of the wall concrete etc..

24. PURPOSE : ☼ Make some holes for blast of the rock

25. PURPOSE : ☺ To create the tunnel ☺ To unload mountains, hard rock ☺ To disassemble the road ☺ To unload rail KA ☺ To disassemble mineral deposit

29. TOOLS 1 Kompressor : machine that functions to collect, store, increase the air pressure in accordance with its capacity.

30. KOMPRESSOR Kompressor is : • Tool to generate a working air bertekanan high. • In the field of mining work, press the air from the kompressor is used for various purposes, including to:

31.   Advanced. - Drilling operation (the            Jack Hammer).       - Heating Ventilation Tambang.      - Clearing the drill hole.            (Mud Water Flushing and Flushing).        - Move the locomotive.

32. COMPRESSOR TYEPES • KompressorResiprok, kompressor this bekerjanya same with hand pump that is where the air pressure from the diminution volume (air compression), so that the air collected in a tube and eventually have a large amount of pressure, so can the "Jack Hammer".

33. ADVANCED • Kompressor This can create air pressure higher than kompressor type Resiprok. Air press generated from this kompressor not directly but bertahab.

34. advanced • Suppose bertekanan 8 desired air atmosphere, the pressure of it is not made directly from 1 atm, but bertahab, namely from 1 atm, increased to 2-3 atm, the new first stop was extended to a pressure greater achievements so that air pressure on the kompressor reach 8 atm.

35. ADVANCED • Kompressor is bekerjanya two phases is called "double-stage Compressor", while the kompressor is only one tahab called "stage Compressor singgle). During this tool kompressor work, silindernyaakan heat is required for air conditioner with a

36. ADVANCED • "Cooler". Refrigerant is there are two kinds, namely:         - Inter Cooler, cooling on            compressor which is located on the            phase one stage            next, there is only kompressor on multi-stage.

37. ADVANCED • - After cooler, the cooler the kompressor where pendinginnya located after the air is pressed out.

38. MECHANISM OF KOMPRESSOR • Besides as a source of energy to drive a series of machines such as drill Jack Hammer, CRD and high-pressure air from the kompressor is also to clean the hole and drill to chisel pendingi. • Kompressor capacity stated in C.F.M. (Cubic Feet Per Minute). • And the free air dihisap and kompressor is pressed by air with tekana local atmosphere, so it is not always bertekanan 1 atm (14.7 psi), the air pressure at the height of zero from the surface sea water.

39. ADVANCED . Provision of supplies and materials fuel.     . Kompressor's operating costs.

40. Advanced equipment ... 2.Slang high air pressure, distributing its functions to the air from the high bertekanan to kompressor Jack hammer 3.Oiler/lubricator, functions to lubricate or lubricant on the hammer's not easy to be rusty.

41. “ROTARY PERCUSSIVE DRILL” • This is the principle of rotating the strike or crash. In general, the tool is used as a shoot holes / hole ledak (blast holes). • The type of "Percussive Rotary" is as follows:

42. Jack Hammer : • The tool is based on the drill functions can be divided into three kinds, namely:             a. "Drifter".                 This tool is used for drilling                 horizontal section and is a tool drill tumbuk playlist terberat, namely between                 50 - 100 kg, which by ditopang                "Mounting device" as a buffer                 which is called the

43. Jack Hammer : b.”Stopers”. Used for the drilling direction, especially over the use on the land Down Tambang. Weight of the tool is about 30 - 50 kg.

44. Jack Hammer : C.”Sinkers” This tool is used in the making of the hole shoot-way down. Weight of the tool is approximately 12 -40 kg, and does not use cantilever.

45. Crowler Rock Drill/ CRD • This term is often abbreviated with the CRD, where the differences lie with the "Jack Hammer" is on the mobilitasnya, if Jack Hammer with perpindahannya appointed, while the CRD, it can move itself, because it has the wheels of the chain (Crowler). So that can moved to the place runs itself, (Mob Mob de) can be faster because it can run both its own and is used for areas that are difficult to be more effisien.

46. STEM BORER DAN MATA BOR Stem borer is a style of the work / energy from the engine to drill the drill, drill stem and is usually made of steel with the terms of section six (Hexagonal), and half-rounded octagonal.

47. Various stem borer. Integral Drill Steel. Stem borer that made sharp edges and functions as a brace and bit, and parts of the "Integral Drill Steel" is:            a. Shank Rod, is the stem borakan included in the                drill machine.

48. The Advance of Stem Borer… b. Collar, which is the pro-function to keep out of the "drill - steel "on the drill machine. c. Bit / chisel, brace and bit is the work for the material / material that will be in the drill.

49. Stem Borer Advanced… • Detachable Drill Steel. Is a stem borer, where the drill / pahatnya can plug in pieces, removed from the drill stem / handlebar bor. There are two types: - Type whorl.                                 - Socket Type.

50. Stem Borer Advanced… • Extension Drill Steel. Stem borer is used to add a long series of borer control. To add a set of control drill is a tool used with a link called "coupling sleeve" or "Nepel", where both ends berulir / have a whorl.
