3, The hydraulic geological drill rig is simple in structure. It is light and easy for transference; 4, The mast has the functions of sliding and touching the ground; 5, The spindle lifted and lowered with hydraulic cylinder; 6, This core drilling rig cou...
The mast could be adjusted within the range of angle 0 to 90 degrees for its drilling hole with a low center of gravity and good stability of the overall unit. The hydraulic core drilling rig provides the operator with a nice field of vision and wide and...
HF150RC series drilling rig is full hydraulic top drive type crawler drilling rig which is independently developed by us, it can be used for mining investigation, geological investigation, borehole for water well and observation well, borehole drilling for GSHP syste...
The results provide a novel quantitative measurement for continuously in-situ mechanical profiling by digital drilling data. The findings of the paper can offer a new and effective method for refinement and upgrading of in-situ ground investigation, and can provide researchers and engineers with a ...
Rotary steering drilling system is a high-end piece of equipment in oil and gas development. The reliable operation of its core equipment, the dynamic point-the-bit rotary steerable drilling tool (DPRSDT), is an important prerequisite for the normal operation of the drilling system. In this pa...
Distribution of Microorganisms in the Soil as Affected by Plowing and Subtilling Crop Residues The purpose of this investigation was primarily to determine what effects rate and method of application of residues have on the distribution of microorganisms within the plow-depth layer of soil. RC Dawson...
