Multifunction crawler well drill
It is mainly used in drilling operation such as drilling well, monitoring well, relief well, exploiting coal gas and other exploratory hole projects.
In stone drilling, DTH hammer is applied in the operation, slag is discharged by air pressure and the offstage efficiency is ten times of that of the traditional rotary drilling;
Cutting drilling or cone drilling can be discharged under the effect of slurry; The impact drilling operation also can be adopted and the slag can be discharged by air pressure; The machine is suitable for drilling in compalicated geological conditions;
The maximum drilling depth is 700m, the drilling diameter is 140_ 450mm
