摘要
Abstract
according to the support resistance, circulation resistance, time weighted average working resistance and frequency distribution of 8120 fully mechanized working face in xiadian coal mine. The research shows that: the average periodic weighting distance 21.6m, the average dynamic load coefifcient is 1.67, and the release of top coal caving caused the coal above the roof distance broken, mobile, so that the support resistance, time weighted average working resistance is low.关键词
