小官庄、西石门、玉石洼这三座地下铁矿都是在“文革”时期“边勘探、边设计、边施工”的“三边”工程。由于地质情况和矿岩性质不很清楚就做设计,就开工建设,致使矿山生产初期一直处于被动局面。投产后发现地质情况和矿体形态发生了很大变化,采矿方法不适应,巷道掘进和支护困难,产量很低。为了尽快提高矿山生产能力,冶金部矿山司及时组织了有关科研院所和大专院较,对地下矿难采矿体进行采矿方法技术攻关,制定了生产与科研相结合,科研为生产服务,努力提高矿山生产能力的方针,使小官庄、西石门、玉石洼等地下铁矿的产量在“七五”期间逐年稳步上升,到“八五”末将形成稳定的生产能力。
Xiaoguanzhuang, West Shek Mun, jade depression of the three underground iron mines are “during the Cultural Revolution” “while exploration, edge design, construction” of the “trilateral” project. Due to the geological conditions and the nature of the ore is not very clear on the design, it started construction, resulting in the early production of mines has been in a passive situation. After commissioning, it was found that the geological conditions and ore body morphology have undergone great changes. The mining methods are not suitable for the tunneling and supporting, and the output is very low. In order to improve mine production capacity as soon as possible, the Ministry of Metallurgical Mine Department promptly organized the relevant research institutes and tertiary institutions, mining underground mining technology research, developed a combination of production and research, scientific research for production services, and strive to improve the mining The production policy will enable the output of Xiaoguanzhuang, Xishimen, Jadewa and other underground iron mines to rise steadily year by year during the “Seventh Five-Year Plan” period and to achieve stable production capacity by the end of the “Eighth Five-Year Plan”.
