underground coal mining processing

Underground Coal Mining Department of Environmental

Underground mining activity includes the surface operations incidental to the underground area of extraction. The permit area includes support areas, facilities and roads. Permits are also required for underground exploration activities and processing plants. A coal mining permit must be renewed every five years.

Monitoring Direct Current Resistivity During Coal Mining

2022-5-9  The direct current resistivity (DCR) is sensitive to underground water and can be used to detect fissures during the coal mining process. However, the three-dimensional (3-D) measurement of the DCR is still a challenging task and has not been applied to the practical coal mining dynamic process.
