综合机械化固体物料充填采煤技术是充填开采技术的一项革命性技术，该技术自其研发以来，已在我国平顶山(村庄下)、济宁(密集村庄群下)、兖州(大型河堤下)、皖北(四含水体下)、开滦(铁路网下)等10多个矿区20多个工作面进行广泛的工业性推广，该技术在提高煤炭资源回收率；利用矿区固体物料以及保护矿区建(构)筑物、土地、水体和生态环境等方面具有突出的技术优势，成为解放“三下”压煤及其它呆滞煤炭资源的首选技术。综合机械化固体物料充填采煤技术能实现采煤与充填的一体化作业，这就要求提供矸石运输与充填的通道和设备并保证采空区充填的矸石具有足够的密实度，而在常规的工作面设备配套方式中既没有运输和充填矸石的设备和通道，也不能在液压支架后方的采空区提供足够的充填作业空间，无法实现采煤与充填的一体化作业。
发明内容
本发明的目的在于提供一种解放“三下”压煤的煤矿固体充填采煤工作面设备配套方法，解决现有固体采煤技术中固体充填材料的运输通道、夯实动力以及充填采煤作业空间的三大技术难题。
为实现上述目的，本发明采取以下述技术方案：该工作面设备配套方法如下：采煤机截割下的煤经由采煤工作面内的刮板输送机运至运煤巷并转载至运煤设备，由运煤设备运出采煤工作面；充填工作面所需要的矸石由运矸带式输送机转载至自移式转载输送机，由自移式转载输送机转载至多孔底卸式输送机的机尾上，矸石经由多孔底卸式输送机中间段卸载至多孔底卸式输送机下方采空区内并经过夯实机构反复夯实。
采煤工作面由充填采煤液压支架前顶梁掩护，充填工作面由充填采煤液压支架后顶梁掩护，运煤巷和运矸巷开设在采煤工作面两端，配套方法的设备由采煤机、刮板运输机、运煤设备、运矸带式输送机、自移式转载输送机、充填采煤液压支架、夯实机构、多孔底卸式输送机组成；所述的多孔底卸式输送机包括机头、驱动电机、机头升降平台、输送机中间段、机尾、机尾升降平台组成；采煤机、刮板运输机、充填采煤液压支架布置在采煤工作面内；运煤设备、机头、驱动电机、机头升降平台布置在运煤巷内；运矸带式输送机、自移式转载输送机、机尾、机尾升降平台布置在运矸巷内；夯实机构、输送机中间段布置在充填工作面内；
所述的输送机中间段悬挂在充填采煤液压支架后部，夯实机构铰接在充填采煤液压支架底部；运矸带式输送机端部与自移式转载输送机后部搭接，自移式转载输送机前部与机尾搭接，机尾放置在机尾升降平台上；运矸带式输送机与自移式转载输送机二者中心线重合；机头、驱动电机放置在机头升降平台上；驱动电机与运煤巷平行布置且二者 中心线重合；运煤设备后部与机头升降平台前部通过铁链柔性连接，运煤设备的中心线与运煤巷的中心线重合；刮板输送机的机头布置在运煤巷内并与运煤设备搭接，每台充填采煤液压支架均与刮板输送机铰接，铰接点间距为1500mm；采煤工作面布置相同型号及结构的充填采煤液压支架，通过滞后支护的方式实现过渡段的管理。
