利用围岩松动圈理论，对已开拓水平同类岩石进行分类，其应用已经很成熟并带来巨大经济效益。但对于同一水平未曾揭露过的岩层，立井深一水平或新建矿井，进行围岩松动圈预测和分类，仍然是正在研究中的课题。在现场实测的基础上，利用灰色系统理论对此进行了松动圈灰色预测研究。 Based on the loose ring theory of surrounding rock, the classification of rocks of the same type has been exploited. Its application has been very mature and has brought huge economic benefits. However, it is still a subject under study that rock layers, vertical wells or new mines in the same level have not been exposed, so as to predict and classify the loose ring of surrounding rock. On the basis of field measurements, this paper uses the gray system theory to study the loose gray prediction.
