采掘装备绿色设计与评价技术研究

Research on green design and evaluation technology of mining equipment

针对采掘装备设计存在过于依靠经验、人工计算偏差大而导致设计质量差、设计周期长等问题,以矿山采掘装备绿色设计为切入点,围绕需求分析、绿色设计、评价三大环节分析了采掘装备绿色设计总体方案,从设计绿色化、制造工艺绿色化、激光熔覆修复再制造技术、掘进系统智能化及状态监测与故障诊断五方面分析了采掘装备绿色设计关键技术。以采煤机为例,对其进行绿色设计分析,从资源、人机、能源、环境、经济、技术六大属性出发,构建了采煤机绿色设计评价指标体系,建立了采煤机绿色设计信息数据库。在设计阶段考虑采掘装备的绿色性,可提高采掘装备的生产质量,对推进煤炭行业绿色设计资源的共建共享及增强行业绿色化设计的示范作用具有重要意义。

In view of problems of poor design quality and long design cycle in design of mining equipment caused by relying too much on experience and large deviation in manual calculation,taking green design of mining equipment as the starting point,the overall green design scheme of mining equipment is analyzed based on three links of demand analysis,green design and evaluation,the key technologies of green design of mining equipment are analyzed from five aspects:green design,green manufacturing process,laser cladding repair and remanufacturing technology,intelligent tunneling system,and condition monitoring and fault diagnosis.Taking shearer as an example,its green design is analyzed.Starting from six attributes of resources,man-machine,energy,environment,economy and technology,evaluation index system of green design of shearer is set up,and green design information database of shearer is established.Considering greenness of mining equipment in design stage can improve production quality of mining equipment,which is greatly significant for promoting co-construction and sharing of green design resources in the coal industry and enhancing the demonstration of green design in the industry.
