煤层稳定性的评价是否准确至关重要，不仅关系到煤田勘查过程中工程布置，更关系到矿井开采过程中工作面布置与开拓方式的选择。通过采用变异系数法和等性块段指数法两种方法对尤氏煤矿二1煤层稳定性进行分析评价，这两种方法各有其优越性和实用性，并相互佐证其结论的准确性，确定本区二1煤层为较稳定煤层。

It is very important of accurately evaluating the stability of coal seam,which is not only refer to the engineering layout in the process of coal prospecting,but also relate to the layout of working face and choice of exploit way in the process of mining.Two methods are adopted to analyze and evaluate the stability of Youshi coal mine Ⅱ1 coal seam,of which are variation coefficient method and equi-block index method,and they have their advantages and practicality,and mutually testifies the accuracy of conclusions,determines that the Ⅱ1 coal seam of this area is relatively stable.
