Xinhua Xining, Dec. 4 (Xinhua Daqian) from Qinghai Province Science and Technology Agency reporter informed that the "Eleventh Five-Year" period, Qinghai focus on technical integration and innovation in the field of circular economy has developed with independent intellectual property rights, competitive projects and products, promote the use of many key technologies to the domestic and world advanced level, a strong impetus to the development of circular economy.
In recent years, focusing on recycling economic development, science and technology sector in Qinghai Province and support R & D focus to industry, focusing on the rich Qaidam Basin, based on minerals, salt, non-ferrous metals, new energy and other resources, and guide the Salt Lake Group and other companies and Chinese Academy of Sciences, Tsinghua University , East China University of Science and Technology Innovation and other research institutions to establish alliances to strengthen the scientific and technological research, the Qaidam circular economy pilot zones and technology support was significantly improved.
5 years, development and utilization of salt lake resources into a new phase, Salt Lake Potash production technology in the traditional production process of potassium chloride flotation is based on the technological leap made 3 times to achieve stable production of millions of tons of potash fertilizer, potash fertilizer industry technology , product quality and international standards.
Meanwhile, lead and zinc in the deep XITIESHAN made a breakthrough in prospecting, extending the mine life. The Xuanye experimental research, improve the recovery of lead and zinc. Exploration technology continues to progress, found a group of cobalt-gold deposit, copper and cobalt deposits, rock gold, silver, rare minerals dispersed elements proved reserves.
Oil and gas exploration, reservoir fractures have been captured to identify, describe and predict the key technologies and key fractured reservoir exploration technology and methods, the new control of oil reserves 500 million tons, horizontal drilling technology breakthrough to ensure that the gas field The stable and production. Wood in the coal mine shaft in permafrost regions to develop experimental research work to solve the coal mines in permafrost regions supporting the stability of the slope to protect the permafrost area of coal mine production safety and stability.
Technology Solutions Director of the Office of Qinghai Province, said the source, 5 years, Qinghai in the Qaidam the implementation of circular economy pilot zones were 386 projects to fund capital 95,830,000 yuan. In addition to capturing the key technology development and utilization of resources, science and technology research will also focus on the efficient and clean burning, industrial waste heat recovery, energy saving, new energy, industrial cleaner production technology development and applications, so that constraints in key industries, enterprises and Energy Conservation reduction of technical bottleneck breakthrough.
新华网西宁12月4日电 （记者王大千）记者从青海省科技厅获悉，"十一五"期间，青海突出技术集成与创新，在循环经济领域开发出了一批拥有自主知识产权、具有市场竞争力的项目和产品，许多关键技术的推广应用达到国内和世界先进水平，有力推动了循环经济发展。
近年来，着眼于循环经济发展需要，青海省科技部门将研发和支持重点转向工业，重点依托柴达木盆地丰富的矿产、盐湖、有色金属、新能源等资源，引导盐湖集团等企业与中科院、清华大学、华东理工大学等科研院校建立科技创新联盟，加强科技攻关，使柴达木循环经济试验区的科技支撑能力明显提高。
5年间，盐湖资源开发与综合利用进入新阶段，盐湖钾肥生产工艺技术在传统的氯化钾正浮选生产工艺基础上，取得了3次技术飞跃，实现了百万吨钾肥稳定生产，钾肥工业技术、产品质量与国际接轨。
同时，锡铁山铅锌矿在深部找矿方面取得了突破性进展，延长了矿山服务年限。经选冶试验研究，提高了铅锌回收率。勘探技术不断进步，发现了一批钴金矿床、铜钴矿床、岩金矿、银矿，稀有分散元素矿产中已探明储量。
石油天然气勘探方面，已攻克储层裂缝识别、描述和预测等关键技术与裂缝性油气藏勘探关键技术方法，新增控制石油地质储量500万吨，水平钻井技术也实现突破，确保了涩北气田的稳产和增产。木里煤田多年冻土区煤矿井工开拓试验研究，解决了冻土地区煤矿采煤边坡支护稳定性问题，保障了冻土地区煤矿生产安全稳定运行。
青海省科技厅厅长解源表示，5年来，青海在柴达木循环经济试验区共实施科技项目386项，资助资金9583万元。除攻克资源开发利用的关键技术，还将科技攻关重点放在高效清洁燃烧、工业余热利用、建筑节能、新能源、工业清洁生产等技术的开发和应用上，使制约重点行业、企业和工程节能减排的技术瓶颈取得突破。
