薄煤层智能化无人工作面成套装备与技术

Complete equipment and technology for intelligent unmanned working face in thin coal seam

  • 摘要: 薄煤层开采存在工作面环境恶劣,劳动强度大,人员无法直立行走,生产效率低,跟机作业难,成套装备性差,自动化程度低,系统协控困难大,易造成生产安全事故等问题,目前薄煤层自动化开采技术主要有刨煤机组和电牵引滚筒采煤机组2种典型方式,刨煤机组自动化开采技术具有结构简单、截深浅、运行速度快等特点,但对煤层条件要求高,过断层适应性差、应用范围窄,硬煤开采困难,电牵引滚筒采煤机组自动化开采技术具有适应性强、适应范围大等特点,但结构尺寸大、截割功率低、经济效益低。为了有效解决薄煤层开采存在的难题,提出一种新的链牵引薄煤层采煤运输支护成套装备与技术,它有别于刨煤机组和摇臂式采煤机组开采技术,主要包括截割部、输送部、支护系统、牵引部、拖缆部、转载破碎部、输送带输送部、移动变电站、乳化液泵站及相应的智能控制系统,通过链牵引系统牵引截割部完成垂直进刀、强力割煤、调高挖底等功能,实现工作面煤炭的快速截割、快速装载、快速输送、及时移架、推移刮板输送机,完成割煤、牵引、运输、移架的联动控制,最终实现薄煤层开采的生产自动化、割煤智能化、管理信息化和工作面无人化。

     

    Abstract: Thin coal seam mining has many problems and inconveniences,namely,bad working environment,the intensity of labor is big,people can′t walk upright,even unable to enter,the production efficiency is low,with machine operation difficult,poor equipment,low degree of automation,the system of control difficulty is big,easy create any production safety accident,the thin coal seam mining automation technology are mainly coal units and electric traction roller way of two kinds of typical coal and coal mining technology automation units has a simple structure and cutting depth,fast,but the demand is high,the conditions for coal seam through fault poor adaptability,narrow application range,hard coal mining difficulties.The automatic mining technology of electric traction drum shearer has the characteristics of strong adaptability and large adaptability range,but the structure size is large,cutting power is low and economic benefit is low.In order to effectively solve the above problems of thin coal seam mining and inconveniences,put forward a new chain traction thin coal seam mining transportation supporting complete sets of equipmentand technology,it is different from coal unit and rocker arm type coal mining technology,mainly including cutting department,delivery department,supporting system,traction,towing,reprint broken,belt conveyor,mobile substation,emulsion pump and the corresponding intelligent control system,through the complete chain traction system traction cutting part vertical feed,strong cutting coal and raise the undercover,and other functions,implementation of working face coal fast cutting,fast loading,fast delivery,moving frame,pushing sneak in time.Linkage control of coal cutting,traction,transportation and shifting frame is completed,and finally,the production automation of thin coal seam mining,coal cutting intelligence,management information and working face unmanned is realized.
