上半年,全公司最高开动岩心钻机24台,完成工程量40965米,台月效率达到736米,纯钻率44.7％,一级孔率98.8％,有效工程率99.7％,钻孔合格率100％,单位成本99.46元,各项主要经济技术指标达到冶金系统的先进水平。在1986年全公司探矿生产取得较好成绩的基础上,今年上半年的生产效率和质量又有了大幅度提高的原因是:①继续深化体制改革;②进一步完善经济承包责任制;③全部开动的机台都采用绳索取心新技术;④加强机台的全面管理,开展机台晋等升级、创一流水平和立
In the first half of the year, the company started up to a maximum of 24 core drilling rigs with a capacity of 40,965 meters. The monthly efficiency reached 736 meters, the pure drilling rate was 44.7%, the primary porosity rate was 98.8%, the effective engineering rate was 99.7% and the drilling qualification rate was 100% , The unit cost of 99.46 yuan, the major economic and technical indicators have reached the advanced level of the metallurgical system. On the basis of better achievements of the company-wide prospecting and production in 1986, the production efficiency and quality in the first half of this year have been greatly improved because: ① continue to deepen the system reform; ② further improve the economic contract responsibility system; ③ all started Of the machines are used rope coring new technology; ④ strengthen the overall management of the machine, to carry out machine upgrades Jin, a first-class and legislation
