China suffers the worst coal mine disasters in world. Lots of miners lose their lives or suffer occupational injury. Fortunately, is developing vigorously intelligent mining, which combination traditional mining and latest technology. Mining expects to relieve solve safety, health intensive labor issues ensure energy security by applying mining. This paper fully reviews promotion safety. Firstl...

Strain is an important parameter for assessing the potential impacts resulting from mine subsidence movements. However, strain resulting from mine subsidence is also one of the most difficult parameters to predict accurately. A number of methods can be used to predict strain, from simple empirical relationships, to more complex statistical approaches. This paper looks at some of these predictio...

When exploiting Jurassic-era coal resources in Northwest China, there are risks of water inrush and sand burst disasters from seam roofs. To improve the safety mining, it is imperative to accurately objectively evaluate risk sandstone aquifers roofs reasonably effectively prevent control disasters. In this paper, 221 mining area Shilawusu Coal Mine was considered. By combining basic geological ...

One of the main concerns of an underground coal mining engineer is the safety and stability of the mine. One way that the safety and stability can be ensured is to know and understand the coal mine geology and how it reacts to the mining process. One technique that has shown a lot of success in the coal mining industry for geologic technical evaluation purposes is the coal mine roof rating (CMR...

This paper describes the effects of igneous intrusions on pore structure and adsorption capacity of the Permian coals in the Huaibei Coalfield, China. Twelve coal samples were obtained at different distances from a ~120 m extremely thick sill. Comparisons were made between unaltered and heat-affected coals using geochemical data, pore-fracture characteristics, and adsorption properties. Thermal...
