Abstract

Baodian mine is gradually mining shallow area with thin bedrock, and failure height of overburden strata in shallow area has a certain difference from one of thick bedrock area. According to the measurement of “Two zones” in 5304-1top slice face and 5304 mechanized sublevel caving face, the paper confirms the heights of caving zone and water flowing fractured zone. And then the heights are compared with forecasts of empirical formula. In the end development characteristics of strata damage is concluded.
