Core drilling rig is a kind of core drilling equipment, which is mainly used for the survey and exploration of metal and non-metallic solid minerals, in addition, can also be used for engineering geological survey, hydrogeological survey, oil and gas field survey and exploration and drilling wells.
The lightweight core drilling rig adopts a modular design, which can realize rapid assembly and decomposition, and a lightweight design, which is convenient for mountain handling and reduces the initial preparation cost of the drilling rig.This drilling rig is suitable for geological survey exploration, geophysical exploration, road and construction exploration, and drilling projects such as blasting and breaking holes.Different drill bits can be selected for drilling according to different formations, and 2-9 grades of sandy clay and rock formations can be drilled.
