Introduction
Soil is a key factor in the design and construction of all civil engineering works such as buildings, bridges, dams, and all kinds of structure. Soil behaves differently under different environmental conditions, and it is essential to u......
photogrammetry
Photogrammetry
Photogrammetry is the science of capturing 2D or 3D images from photographs and using them to measure or model the surface or object being photographed. This is accomplished by triangulation or by stitching together images taken from different angles and distances. Photogrammetry c......
rock drillability
Rock Drillability Rock drillability is the ability of rocks to be drilled or mined using a drilling machine, such as a jackhammer or rotary drill. It is an important property that affects rock fragmentation, excavation methods, drilling and blasting operations, and other applications in the mining ......
Surface mine slope survey
Open-pit slope survey
Open-pit slope survey is an important part of open-pit mining project assessment and design. In the survey of open-pit slope, various geological information is found and the basic frame of open-pit slope maintenance is determined; meanwhile, the stability of open-pit slope i......
induced polarization
Joule-Thomson Cryogenic Refrigerator
The Joule-Thomson cryogenic refrigerator, also known as the J-T refrigerator, is a device used to cool objects to temperatures near absolute zero. It works by expanding a pressurized gas, resulting in a drop in its temperature due to the Joule-Thomson effect. T......
Topographical Mapping
Terrain mapping is a method of creating detailed geographical maps using a combination of aerial photography, satellite imaging and GPS data. This data is then analyzed and interpreted to create detailed, accurate maps of terrain features such as mountains, valleys, and rivers. Terrain mapping can......
Water supply hydrogeological survey
Water Resources Surveying
Water resources surveying is a key component of the management of water resources. It is the process of measuring and interpreting the characteristics and characteristics of water bodies, including surface and groundwater. The purpose of this type of surveying is to eval......
Earthquake Observation
Ground Motion Microseismic Observation
Microseismic monitoring is a technology that detects and records microseismic activities of the Earth’s subsurface. The technique provides direct insight into the mechanical behavior of a rock mass, thus enabling detailed characterization of the subsurface.......
Hole Accident
Design Mistakes Causing Subsurface Disaster
Subsurface disaster can occur individually or in clusters as events and disasters, both through natural events and by significant design mistakes, which can have tremendous and far reaching impacts on people, environment and infrastructure. This can be ......
