综采工作面支架工作阻力异常变化的灰色灾变预测

GREY CATASTROPHE PREDICTION OF ABNORMAL CHANGE OF WORKING YIELD OF SUPPORT IN FULLY—MECHANIZED WORKING FACES

本文利用灰色理论中的灾变预测方法,研究了综采工作面支架工作阻力异常变化的规律,并建立了相应的灰色预测模型。实例分析证明效果较好。

This paper studies the law of abnormal change of working yield of support in fully-mechanized working face by means of the catas- trophe prediction method of grey theory and established the corresponding grey prediction mode. Analysis of practical examples demonstrates that it achieves good results.
