我矿地质情况复杂,近几年来,“三级矿量”不足,我们加强了对水平钻的管理,加快了钻探速度,探明了矿体赋存情况,获得了一定经济效益。 一、我矿使用水平钻的经过 我矿三一五标高以上的硫铁矿受地下水作用,百分之九十氧化成褐铁矿,1969年由涟钢田湖铁矿设计开采,当时,因地质勘探程度低,矿体形态复杂,仅以省地质局提交C_2级储量,作为边采边探的建矿依据,故设计时,就考虑以钻探坑探相结合,提高储量级别,满足生产需要,但是,当时我们运用水平钻探矿没有经验,技术管理水平低,因此,进尺少,效果差。
Due to the complicated geological conditions in the mine, in recent years, “tertiary ore quantity” is not sufficient. We have strengthened the management of horizontal drilling, accelerated the drilling speed, proved the occurrence of ore bodies and obtained certain economic benefits. First, the level of mine using my diamond mine after the elevation of 325 Elevated pyrite by groundwater, 90% oxidation into limonite, Lianyungang Iron Lake in 1969 by the design and mining, at that time due to Due to the low degree of geological exploration and complex ore bodies, C_2 reserves are only submitted to the Provincial Bureau of Geology as the basis for the mining of side-edge exploration. Therefore, considering the combination of drilling and prospecting, the reserve level should be increased to meet production needs However, at that time, we did not have experience in using horizontal drilling and the level of technical management was low. As a result, there were fewer footage and weaker results.
