目前的地下围岩分级,未能综合围岩特性和结合生产实际需要,因而不能满足工程设计、施工、科研、教学的要求。我国地下矿产资源丰富,随着采矿事业的向前发展,开采的矿山愈来愈多,为摸清围岩性质、稳固程度与生产上所需要的支撑系数的相互关系,更好地为生产矿山服务,多、快、好、省地采掘地下资源,科学而统一的围岩分级方法是很必要的。本文提出Ⅶ级分类法供大家讨论。
The current underground rock classification, failed to synthesize the characteristics of the surrounding rock combined with the actual production needs, which can not meet the engineering design, construction, scientific research, teaching requirements. With the rich underground mineral resources in our country, with the development of the mining industry, more and more mined mines have been developed. In order to find out the correlation between the nature and the firmness of the surrounding rock and the supporting factors needed for the production, Services, and more, faster, better, provincial underground mining resources, scientific and uniform wall rock classification method is necessary. This paper presents Ⅶ level classification for your discussion.
