我国已开采一百多个大理石矿山,经过正规地质勘探的矿区只有宜兴、杭州、丹东、县、平度、衢州等十多个矿区。而石材矿山的地质勘探工作,目前还无统一的规范可遵循,积累经验也不足,很多勘探矿区的地质工作是在边工作,边摸索的基础上进行。近几年来我们通过配合国内几个大理石矿山的地质勘探,在开采设计工作取得了一些经验和教训。现提出一些粗浅的看法,供广大地质工作者共同探讨。一、实测荒料率实测点的选取、统计及计算实测荒料率的计算,在已经开采的老矿山可以通过实际统计资料来计算统计荒料率。而对大部份勘探矿山来说是未经开采的,需要通过试采,取得实测荒材率数据,来对理论荒料
More than 100 marble mines have been mined in China, and only a dozen ore mining areas such as Yixing, Hangzhou, Dandong, Xian, Pingdu and Luzhou have passed through formal geological exploration. The geological exploration work of stone mines, there is no unified standard can be followed, the accumulation of experience is also inadequate, many of the geological exploration of the mining area is working on the edge, while proceeding on the basis of exploration. In recent years, we have obtained some experiences and lessons in mining design work by cooperating with the geological exploration of several marble mines in China. Present some superficial views for the majority of geologists to discuss together. First, the actual measured block material rate measurement point selection, statistics and calculation of the actual measured block material rate calculation, in the old mines that have been mined can be calculated through the actual statistics statistical block material rate. For most of the prospecting mines, it is unmined, and it is necessary to pass the test mining to obtain actual surveyed wood rate data to analyze the theoretical blocks.
