Geological Features of Kailuan Coal Mine and the Laws of Pressure Bump for Deep Mining

Abstract:

Pressure bump in coal mine production safety is a serious disaster. Geological conditions in Kailuan Mine are complex. Coal strata based on the Carboniferous - Permian coal. The roof and floor are made of sandstone and mudstone with poor rigidity. Fault development and mine have large amount of water inflow. Most of mine are already getting into the mining stage over one thousand meters deep. Increasing stress and high stress induced pressure bump as a key factor. In this paper, according to geological characteristics of Kailuan Coal, it analyzes the impact and the laws of pressure bump in the representation of deep mining phase, which have certain reference for coal mine safety production.
