The development of resource-based industry provides an important guarantee for promoting the national economic growth and industrialization process.A comprehensive and in-depth understanding of the research situation of Chinese scholars in the field of resource-based industry is conducive to grasp the overall research situation,promote the expansion and deepening of resource-based industry research,and promote the development of resource-based industry.In this paper,CNKI database was used as the data source to collect the core and above journal papers on resource-based industry from 2000 to 2020.CiteSpace was used to draw knowledge map from the distribution of authors and research institutions,key words co-occurrence network and time zone map.Based on objective data and knowledge map,this paper analyzes and summarizes the research status,research hotspots and knowledge evolution process of resource-based industry in recent 20 years.The research shows that the number of papers published and the fund support rate show an overall upward trend.Only a few academic teams have been formed among the authors,and the cooperative relationship between most authors is not obvious,showing a scattered and free state.Research institutions carry out research based on regional characteristics and disciplinary advantages,but do not form a close cooperation network,and some of the cooperation is only internal cooperation.The research focuses on the development of resource-based industries,resource-based cities,resource-based industrial clusters,industrial structure,resource-based industrial chain and resource-based industrial agglomeration.The process of knowledge evolution can be attributed to the gradual extension,refinement and in-depth research of the concept,theoretical basis and development countermeasures of resource-based industries,as well as the cross discussion and coordination of different research fields.The application of research methods has gradually diversified from scratch,and has changed from qualitative analysis to quantitative analysis.In the research area,scholars focus on the central and western regions.The future research direction can be explored from the aspects of relevant theoretical research of resource-based industry,innovative development model and sustainable development research.

矿用重卡无人驾驶项目已可开展工业性试生产运行
2022年10月17日,国家能源集团神延煤炭西湾露天煤矿31台220 t矿用重载无人驾驶卡车编组安全运行超过200 000 km,运输超过1 400万t,实现了露天煤矿大型矿卡无人驾驶批量编组安全示范应用。
国内首个全矿大型矿卡无人驾驶批量应用科技项目,于2020年落地国家能源集团神延煤炭西湾露天煤矿。经过不断加大科研攻关力度,通过持续的技术提升和运营管理模式的优化,国家能源集团神延煤炭解决了无人驾驶运输实际生产过程中的各类难题,逐步提升矿卡无人驾驶运输系统效率和安全性能。
2021年11月至今,矿用无人驾驶卡车开展日夜双班常态化生产作业,经受住了富水露天矿山、坑洼泥泞道路、风雪雨雾和严寒低温等恶劣矿山环境考验,实现了多铲多平盘多卡车编组的工业化生产运行。31台220 t矿用无人驾驶卡车历经“试验场、土方重载试验、岩石重载、生产作业”的研发、试验和生产实践流程,测试完成800余个试验项点,其中涉及碰撞和倾覆等安全项点453个,为安全可靠生产运行提供保障。系统一次性通过了国家矿山机械质量检验检测中心的33个项点权威质检,在安全、性能和功能等方面得到权威认证。同时完成了50余台协同推土机、洒水车、平路机等车辆改造、调试、协同作业,取得良好的安全运行效果。
评审专家一致认为,该项目作为国内首个全矿大型矿卡无人驾驶批量应用、国内首个采用4G+5G通信安全冗余、国内首个双编组在富水地质、大风沙环境下进行工业化生产作业的矿卡无人驾驶项目已通过各种改造、调试、编组运行试验及检验,各项性能达到了安全运行要求,可以开展工业性试生产运行。
项目在顺利通过安全评审后,可形成一套智能矿山(露天)标准体系,提升集团内部露天板块的整体竞争力,带动我国露天煤矿的智能化应用,达到减员增效、绿色安全的效果,全面提升管理水平。同时也以矿卡无人驾驶为突破口,进一步研究露天矿山智能化与无人化,为建成多系统集成的智慧矿山体系提供强大助力。
