摘要
Abstract
In order to grasp mine pressure behavior laws,strata structure features and support adaptability of fully mechanized working face with 7.0 m supprot,fully mechanized caving mining experiment was carried out at 22303 working face in Bulianta Coal Mine with 7.0 m support.On the basis of measuring advanced mine pressure of different mining stages of two roadways at 22303 working face with 7.0 m support,numerical modeling is used to analyze the change of abutment pressure and the change of two lanes bearing pressure with mining height.Results show that the stress influence scope of large mining height model is gradually increasing with the mining,and the growth of impact scope is rapid and stress value increases rapidly,and the advanced effect area caused by mining is 65 m.关键词
