薄煤层无人工作面自动化开采技术应用

针对某矿薄煤层保护层安全高效开采的需求,提出了对其2号薄煤层进行上保护层无人工作面开采的设计方案;根据2号薄煤层22201首采保护层工作面的实际情况,给出了22201无人工作面的采煤机、液压支架、刮板输送机的配套选型,详细介绍了22201无人工作面自动化控制系统的网络结构及采煤工艺。现场工业性试验结果表明,该方案可自动完成割煤、移架、推刮板输送机和顶板支护等生产流程,实现了薄煤层工作面的自动化开采。

Application of automatic mining technology of unmanned coal face of thin seam

In view of requirement of safe and high efficient mining for protection layer of thin seam of a coal mine,the paper proposed a design scheme of unmanned coal face mining for upper protection layer of No.2 thin seam of the coal mine.According to actual situation of 22201 first coal face of the No.2 thin seam,it gave matching equipment selection of shearer,hydraulic support and scraper conveyor of the 22201 unmanned coal face,and introduced network structure and mining process of automatic control system of the 22201 unmanned coal face in details.The industrial test result shows that the scheme can automatically finish production process of coal cutting,support advancing,scraper conveyor pushing and roof supporting,and realizes automatic mining for thin seam coal face.
