Shaft, chute, inclined shaft survey
Vertical well, slipway, inclined well exploration
Vertical wells, slipways, and inclined wells are all important exploration techniques for underground resources. With these techniques, an exploration company can carefully assess the extent and location of resources and make an informed decision ......
rocks and rock masses
Rocks and rock masses are in the Earth’s high pressure, high temperature environment and combined with the effects of long-term weathering and erosion. It is an important mineral raw material forming the surface crust and mantle of the earth, and plays an important role in the circulation of the ......

Groundwater
Groundwater is a resource that is often overlooked and taken for granted - yet it is an invaluable resource for many people around the world. Groundwater is the water located beneath the surface of the earth in the numerous deposits called aquifers. This stored water is a vital source......
groundwater discharge
Groundwater Discharge
Groundwater discharge is the natural release of subsurface water from underground aquifers, or bodies of rock, composed of densely compacted material that may include clay layers, sand, and gravel. Groundwater is typically released in areas where the aquifer is exposed on the......
Engineering Geophysical Exploration Instruments
Geophysical Exploration Instruments
Geophysical exploration instruments are an important tool for geologists and engineers to understand the processes and materials that make up the Earths crust. These instruments measure various features of the Earth, including seismic activity, resistivity, and......
resistivity method
Resistivity Method
The Resistivity Method is a direct current (DC) electrical geo-survey measurement technique used to determine and map soil and groundwater locations and characteristics. With the Resistivity Method, electric current is passed through two electrodes installed into the ground, ca......
