Coal strata strength is included as a vague term in most of the pillar design formulas, either as a questionable fraction of the intact coal strength or a size-dependent relationship for scaling down a laboratory value to the in situ strength. In order to introduce a coal mass strength criterion which would be compatible with current design trends, the …

85 and enjoys a rich history stretching back nearly 2600 years. Coal-mining has been carried out for 900 years in Xuzhou. The setting up of the Liguo Iron and Coal Mining Bureau in 1882 marked the beginning of the large-scale exploitation and utilization of coal, as well as launching modern industrial processes in Xuzhou (Chang et al. 2011).

The first step in a coal mine design is a realistic geometrical modelling of the coal seam (s). The structural features such as faults and folding must be reliably implemented in 3D seam models.

Coal has occupied a predominant position in the global energy market as a conventional energy source. As far as China is concerned, coal remains a ballast and a stabilizer in primary energy …

Sustainable mining practices is a concept that embeds the principles of sustainable development into the whole mine life-cycle, from exploration, extraction and processing through to mine closure. The optimization of coal mine planning and the developing a standardized design for its sustainable development is very challenging …

In deep-seated coal seams (greater than 250 m), a few Indian coal mines have been developed using the bord and pillar method up to 525 m depth.

Green infrastructure is a concept aimed at realizing a strategically planned network of valuable natural and semi-natural areas, designed and managed to deliver a wide range of ecosystem services and to protect biodiversity in rural and urban settings. In the general post-mining context of China and Germany, this paper suggests and …

Coal mines tend to produce many more seismic events than hardrock mines, which makes it difficult to process the data quickly enough to be meaningful. To help overcome these challenges, researchers in NIOSH's mining program have developed a new approach to monitor rockbursts occurring near the longwall face using fiber optic …

Abstract Sustainable mining practices is a concept that embeds the principles of sustainable development into the whole mine life-cycle, from exploration, …

Large-scale exploitation of underground mineral resources causes surface collapse, reduces land use efficiency, and brings a series of ecological and environmental problems. This is significantly important for the ecological restoration work of mining areas to accurately extract the subsidence range and depth of coal mine surface and …

Renewable energy (wind and solar power, etc.) are developing rapidly around the world. However, compared to traditional power (coal or hydro), renewable energy has the drawbacks of intermittence and instability. Energy storage is the key to solving the above problems. The present study focuses on the compressed air energy storage …

The focus of the hydraulic design was placed on the lower reservoir, as it is the main driver for the rest of the components of the project. A one-dimensional model was implemented in order to ...

2.1 Connections between post-mining regions and the GI concept One legacy of mining operations in China is a large number of post-mining landscapes, generally situated in urban areas that thrived during the country's period of industri-alization. Clearly, such landscapes are associated with a number of negative impacts on the environment as ...
