在大理石找矿勘探工作中,成荒率是评价矿床的首要因素之一。而矿床节理发育特征,不仅影响大理石成荒率,而且关系到矿山采掘方法选择。根据我们实践,现就节理观察统计点布置与成荒率计算,提出一些不成熟的看法,与同志们商讨。节理野外观察统计点布置节理观察和统计,一方面应在地质填图过程中把此项工作作为重要内容之一,此时,观察点分布与地质点相同;另方面可布置专门统计点,并进行大比例尺(通常为1:50～1:100)节理素描。节理统计点是一种长、宽相等,规格为10×10米以上的天然或人工基岩露头面。它应按
In marble prospecting exploration work, rate of succession is one of the primary factors in evaluating the deposit. However, the characteristics of ore-hosting joints not only affect the rate of marble becoming waste, but also affect the selection of mining methods. According to our practice, we now put forward some immature opinions on the arrangement of joint observation statistics and the calculation of the rate of desolation, and discuss with the comrades. On the one hand, this work should be taken as one of the important contents in the geological mapping process. At this time, the distribution of observation points is the same as that of geological points; on the other hand, special statistical points can be arranged and Perform a large scale (usually 1: 50 ~ 1: 100) joint sketch. The joint statistics point is a kind of natural or artificial bedrock surface with the same length and width and specification of 10 × 10 meters. It should press
