摘要: 目前对智能矿山概念、发展规划的研究较多,对智能化建设成果和关键技术的研究较少。基于智能矿山建设的5层技术架构,以大柳塔煤矿智能化建设为例,论述了综采、掘进、运输、供电、供排水等系统的智能化建设情况及成效:共取消井下固定岗位约100个,减少作业人员200余人,降低人工成本4 000万元/a,节约工业水电消耗30%,提高设备利用率5%,提高全员工效10%。指出智能矿山建设的关键点在于拓宽网络通道、统一各子系统接口、关联设备安全可靠和配备专业人才队伍,由此总结了目前智能矿山建设中存在的难点,并有针对性地提出了要攻关的关键技术,包括自动割煤、移动设备人员接近探测、无线传感、集中加油、井口智能安检、无人驾驶等。Abstract: At present, there are more researches on the concept and development plan of intelligent mines, and less researches on the intelligent construction results and key technologies. Based on the 5-layer technical structure of intelligent mine construction, taking the intelligent construction of Daliuta Coal Mine as an example, the paper discusses the intelligent construction and effectiveness in terms of fully mechanized mining, excavation, transportation, power supply, water supply and drainage systems. A total of about 100 fixed mine positions are canceled, and more than 200 operators are reduced. The construction helps to reduce the labor costs by 40 million yuan/a, save the industrial water and electricity consumption by 30%, improve the equipment utilization by 5%, and increase the total workforce efficiency by 10%. It is pointed out that the key points of intelligent mine construction are broadening the network channel, unifying the interfaces of various subsystems, ensuring the associated equipment safe and reliable, and hiring professional personnel teams. This paper summarizes the current difficulties in the intelligent mine construction and discusses the key technologies to be tackled. The technologies include automatic coal cutting, personnel detection of mobile equipment, wireless sensing, centralized refueling, intelligent security inspection at the mine entrance and unmanned driving.
