摘　　要：在辽宁省岫岩县玉石矿采用聚能控制爆破落矿新工艺,取得了良好的试验成果,圆满地完成了科研合同规定的各项技术指标。该新工艺具有技术先进、操作简便、使用安全可靠、经济合理等显著优点,使玉石矿床的损失率控制在10%以下,保证了落下玉石块度达到特级品、一级品在80%以上,完全满足了玉石矿床开采的特定要求,取得了十分可观的经济效益和社会效益,为合理开采我国玉石矿床资源创出了一条新路子。The paper describes the research on the energy-concentrated control blast for ore fragmentation in the new mining method adopted in Xiuyan Jade Mine, Liaoning Province, which achieved good test results and well fulfilled the technical indexes specified in the research contract. This process has the advantages of advanced technology, easy operation, safety and reliability and reasonable economic benefit. It can control the jade loss to be under 10% and ensure that the size of over 80% of the jade fragments can meet the size requirement of super class or first class product, thus being able to fully meet the specific requirement for jade deposit mining and achieving substantial economic and social benefits, which has opened a new route for the rational exploiting China＇s jade resource.
