borehole

Borehole hydromining is a kind of safe and efficient new mining method .

Cross check in cross-borehole shows that root-mean-square error of predicted porosity of simple cokriging is less than 10% compared with that of linear re-gression method.

It is found that the rational located destressing boreholes can induce structural failure of the surrounding rock-mass,consequently the high stress move deeply in the rock-mass,and the stres...

It's a mean of geotechnical investigation, including borehole surveying, costeaning, trenching exploration, test pitting, hole exploration, geophysical exploration and penetration sounding.

The geologist drilled a borehole to collect soil samples.

The borehole was dug deep into the ground to access the water table.

The borehole was used to monitor groundwater levels in the area.

The borehole revealed ancient fossils deep beneath the surface.

The borehole drilling equipment was transported to the site by truck.

The borehole provided valuable data for the research project.

The borehole was sealed after the testing was completed.

The borehole was cased with steel to prevent collapse.

The borehole was equipped with sensors to monitor temperature and pressure.

The borehole drilling team worked around the clock to complete the project on time.
