煤矿无人工作面开采技术研究

为解决中国煤矿开采技术装备普遍落后,煤炭资源回收率低、死亡率高以及"数字矿山"发展缓慢的问题,基于科学采矿理念,分析煤矿开采现状,研究存在的问题,提出高度自动化与传统综采工艺相结合的无人工作面的概念和系统模型,构建了无人工作面的技术框架,分析了需要解决的关键技术,包括采煤机自动调高、采煤机自主定位与导航系统、煤岩界面自动识别、井上-井下双向通讯、采煤工艺智能化、工作面组件式软件和模型及数据库技术,指出了应用状况。

Study on Unmanned Workface Mining Technology

China's coal mining suffers many problems,s uch as backwardness of technologies and equipments,low recovery rate of mineral resources,high mortality,as well as the retardedness in adopting "digital mining".With the concept of scientific mining in mind,this paper analyzes the current status of coal mining,the existing problems,and proposes the concept and the system model of unmanned workface,which combines a high degree of automation and the traditional fully mechanized mining.The technical framework of unmanned workface is outlined.The key technologies are analyzed,including the automatic height-adjustment of shearer,self-positioning and navigation system,automatic identification of coal and rock interface,surface-underground two-way communication,intelligent mining technology,workface component software and models,as well as database technology.Its application is also discussed.
