【摘要】 通过对淮南煤田潘三矿的顶板条件进行分析和研究 ,提出了一套行之有效的评价指标体系 ,运用模糊综合评判方法对煤层顶板稳定性进行定量评价和预测 ,结果表明潘三矿煤层顶板稳定性中等 ,北部比南部稳定性差 ,东部比西部差 ,这可以为采煤工作面顶板安全管理提供科学依据。更多还原

【Abstract】 Based on the study of coal roof conditions in Pansan mine of Huainan coalfield,a set of effective parameters for evaluation of coal roof stability is put forward,the method of quantitative evaluation and prediction of coal roof stability is proposed using fazzy synthesis evaluation.The results show that the coal seam-roof stability of Pansan mine is medium,and the stability is worse and worse from south to north and from west to east.This study can provide scientific evidences for roof safety management is excavate work faces.更多还原
