Vertical electrical sounding (VES) is commonly used to solve many problems regarding groundwater assessment, investigation, exploration, quality/pollution, the boundary, thickness and depth of the aquifer with its different layers

The inclinometer system consists of an inclinometer casing and an inclinometer measurement system. The casing provides contact for sub-surface measurements, while its grooves control the orientation of the inclinometer sensor and provide a uniform surface for measurements.The casing is usually insta

Seismic Reflection (both on-shore and marine) is the most common geophysical methodology used for oil and gas exploration and exhibits the highest degree of technical sophistication in terms of both data acquisition and signal processing capabilities. Seismic reflection surveys provide either 2 or 3

The prospecting method refers to the general name of the working methods and technical measures adopted in order to find the ore deposit. There are mainly geological methods, geophysical methods, geochemical methods, and remote sensing methods.Prospecting ore, also known as prospecting, or census or

Borehole LoggingGeophysical borehole logging can provide accurate data of the physical properties of geologic units and groundwater within the borehole environment.Borehole logging is a time and money-saving approach to gaining detailed information which is otherwise only obtainable from performing

Transient electromagnetic detection has the following advantages⑴ Due to high construction efficiency, pure secondary field observation and sensitivity to low-resistance bodies, it has become the preferred method in the current coalfield hydrogeological exploration;⑵ Transient electromagnetic method

Induced polarization (IP) is a geophysical imaging technique used to identify the electrical chargeability of subsurface materials, such as ore. The polarization effect was originally discovered by Conrad Schlumberger when measuring the resistivity of rock.

Magnetometer, instrument for measuring the strength and sometimes the direction of magnetic fields, including those on or near the Earth and in space. Magnetometers are also used to calibrate electromagnets and permanent magnets and to determine the magnetization of materials.Magnetometers specifica

Using scientific methods to locate waterTo locate groundwater accurately and to determine the depth, quantity, and quality of the water, several techniques must be used, and a target area must be thoroughly tested and studied to identify hydrologic and geologic features important to the planning and

Chongqing supported 359 members of the Wuhan medical team from Hubei Toret to return to Chongqing on three flights. This is the third batch of chongqing to Hubei to support the medical team after the completion of the mission. 　　Since the outbreak of covid pneumonia, Chongqing has sent 18 batches of
