this time I will explain about the mini drill, but have a pretty strong ability.
In a drilling activity, particularly coal drilling many who only know the drill like a long year, jacrow, and other great drill.
In drill activities that we often do, especially for coal, we use a drill powerrig (mini drill), with an average drilling depth of 50 meters.
Powerrig drill tool has the following specifications:
engine:
Yamaha MT-110
Water suction machine:
Robin Alkon 5.0
Shoot machine drill holes:
Robin Alkon 5.0
length of drill pipe :
1.5 Meter
Actually, this drill is enough to read lithologi compilers rather than a site investigation, because the tool is already capable of reaching depths of 50 meters.
It also mobilized a drill rather than using the engine power to rise and fall of the machine into the ground, but rather use human power.
number of members who run this drill as many as 7-9 people, while the tasks are divided by their respective expertise. one person as a drill master, and the other to replace the drill pipe and keep the cutting of the drilling results to be analyzed by a geologist.
Image engine:
sorry if the picture is not good, or there is less pleasing
I'll explain how to use the core barrel sampling using this powerrig and what constraints and advantages of using this machine in the next post ...... seeeee uuuu all next time, bye............
