厚煤层综采工作面冲击地压危险性评估研究
|
摘要
为了判定冲击地压的危险性,以石拉乌素煤矿221上17工作面为例,采用钻屑法对工作面进行冲击地压监测,通过综合指数法和可能性指数诊断法进行评估,判断工作面很可能发生冲击地压。因此,工作面必须制定防冲措施。
In order to determine the risk of rock burst, the 221 up17 working face of Shilawusu Mine is taken as an example, the drilling method of rock burst monitoring on the working surface is adopted, evaluated by comprehensive index method and probability index diagnosis, and the judgment of working face is likely to burst. Therefore, the working face must formulate measures to prevent and control the rock burst.
