我国砂金开采历史悠久.开采方式以土法为主.近年来,砂金开采发展迅速,已由土法开采转为采金船开采.采金船开采砂矿床,由于机械化程度高,生产能力大,经济效果好.已成为开采砂金矿床的主要方法.但由于砂金矿床赋存条件复杂,采金船机械化程度高,生产能力大,要求较高的管理水平及技术水平.而确定合理的采剥路线,编制切实可行的采剥计划,是技术管理工作的一个重要组成部分.我矿是用采金船生产的砂金矿.自1971年投产以来,根据生产情况可分为二个阶段.1971~1978年完不成计划,连年亏损.1979~1981年超额完成计划,连年上缴利润.15项主要技术经济指标,全面超过历史最好水平和设计要求.跨入了先进企业的行列.
In recent years, the rapid development of placer gold mining, mining has been changed from the mining of gold mining vessels. Mining gold mining gold deposit ship, due to a high degree of mechanization, production capacity, The economic effect is good and has become the main method for mining placer gold deposits.But due to the complicated deposit conditions of gold and gold deposits, the gold mining vessel has a high degree of mechanization, large production capacity and high management level and technical level, , The preparation of practical mining stripping plan is an important part of the technical management work.I mine is a gold ore production gold sands gold mine since 1971 put into operation, according to the production can be divided into two stages .1971 ~ It failed to complete its plan in 1978 and suffered losses year after year, surpassing the plan from 1979 to 1981 and surrendering profits in successive years. The 15 major technical and economic indicators comprehensively surpassed the best historical standards and design requirements and entered the ranks of advanced enterprises.
