为实现薛村矿薄煤层94702综采工作面数字化无人开采,根据该工作面地质条件,介绍了采煤机、液压支架、刮板输送机三机设备选型过程;设计并实现了采煤机位置检测、记忆截割自动调高、运行状态实时监控以及液压支架电液控制系统的自动控制等功能。结果表明:通过采用合理的采煤方法和回采工艺,综采数字化无人工作面开采技术安全可靠,可实现自动完成割煤、移架、推移刮板输送机和顶板支护等生产流程。

In order to realize a digitalized unmanned mining of No.94702 fully mechanized coal mining face in thin seam of Xuecun Mine, according to the geologica I conditions of the coal mining face,the paper introduced the equipment selection process of the coal shearer,hydraulic powered supports and scraper conveyor.The loc ation detection of the coal shearer,the automatic height adjustment of the memory cuting,the real time monitoring and control of the operation status,the automatic cont rol of the hydraulic powered support electric and hydraulic control system and other functions were designed and realized.The results showed that with the rational coal mining method and the coal mining technique,the mining technology of the fully mechanized digitalized unmanned coal mining face was safety and reliable and could au tomatically realize the coal cutting,powered support moving forward,scraper conveyor and roof support and other production process.
