hydraulic coal mining
Hydraulic coal mining is a variation of deep mining in which the coal is removed from the seam by means of a powerful jet of water. Hydraulic mining eliminates the need for hand excavation and the costly labour associated with it. It is also more efficient than traditional deep mining techniques, ......

Hydrogeological parameters
Hydrogeology or Hydrogeology is an area of geology that deals with the study of groundwater and itsrelationships with geological environments. It is a subdiscipline of geology which incorporates knowledge of geophysics, hydrology, geochemistry, and other sciences in order to understand and utilize......
Silt and muddy soil foundation investigation
Mud and Mudland Soil Surveying
Mud and mudland are a common feature of the natural landscape, with many areas experiencing higher levels of sedimentation due to the combination of climate, erosion, and human activities. As a result, special attention must be given to mud and mudland when conducti......
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 ......
Karst area survey
Karst landscapes are geographically widespread and are developed predominantly on a variety of carbonate rocks, although areas of limestones, gypsum and hydrogenic rocks are also affected in certain regions. The term ‘karst’ is derived from the Karst topography of the limestone region of Sloveni......
Hydrogeological Mapping
Hydrogeological Surveying and Mapping
Hydrogeological surveying and mapping is a surveying technique used to map out and determine the characteristics of geological formations and soils that may influence the flow of underground water. It is a critical tool for water resource professionals who use......
Collapsible loess foundation investigation
： Investigation of Saturated Loess Ground Base
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......

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 ......
Rock mass deformation
Rock Deformation
Rock deformation is the process by which rock structure is altered due to external forces such as pressure, temperature and shear. It occurs when rocks are subjected to conditions that cause them to deform, or to change shape, volume and stress in response to the forces around th......
