The Relationship Analysis of Surrounding Rock Stability and Continental Sedimentary Environment

Abstract:

The continental coal-bearing strata are mainly formed in the flood plain, delta plain and lake shore subfacies. Through the study on the sedimentary cause of differences of rock strength and sedimentary location, the paper analyzes the internal relationship between sedimentary environment and surrounding rock stability based on different coal-forming models. To take an example of Shendong Coal Mine Area, the differences of surrounding rock stability in various sedimentary environments are quantitative analyzed. The paper’s research promotes the combination between surrounding rock stability and sedimentology.
