我院爆破所承担的国家“七五”攻关项目“立井四米深孔光爆技术”近日通过了专家的技术鉴定。该项目是在“六五”攻关的基础上以改进深孔钻爆器材和技术为主要研究内容,通过理论探讨、数值分析、优化计算、模拟试验和工业试验,实现了立井四米深孔光爆和正规循环作业。 Our hospital blasting bear the national “Seventh Five-Year” key project “shaft four meters deep hole light explosion technology” recently passed the expert’s technical appraisal. The project is based on the “6th Five-Year Plan” to improve deep hole drilling equipment and technology as the main research content, through theoretical discussion, numerical analysis, optimization calculations, simulation tests and industrial tests to achieve a vertical well of four meters of deep hole light Explosion and regular circulation operations.
