针对滚筒采煤机截割效率高、破煤岩能力强、适应性能好的特点,研究开发了基于滚筒采煤机自动化综采成套装备,为解决装机功率与设备配套尺寸难题,采用紧凑型扁平链和极薄煤层刮板输送机铸焊结构中部槽,采煤机截割电动机并行布置,截割电动机与牵引电动机纵横向布置以及板式顶梁、平衡千斤顶叠位布置的液压支架新结构,最大限度降低机面高度,满足薄煤层综机设备配套要求。采用综采工作面集中控制系统,远程监控操作,自动完成双向割煤,实现薄煤层工作面自动化开采。基于滚筒采煤机自动化综采成套装备在峰峰薛村矿0.6~1.3 m薄煤层应用后,实现了巷道集中控制,工作面内无人自动化生产,月产量11.8万t,年产量100万t,实现了薄煤层安全高效开采。

According to the characteristics of shearer's high cutting efficiency, strong rock breaking capacity, good adaptive performance, the automated complete s ets of fully-mechanized coal mining face based on the shearer were developed. In order to solve the matching-size problem of complete sets with the installed power, th e new structure of hydraulic support were adopted, including compact flat armored conveyor chain, ultra thin seam scraper conveyor with cast welding structure of the C entral groove, parallel arrangement cutter motor of shearer, horizontal and parallel arrangement of cutter motor and haulage power, and new structure of hydraulic supp ort of plate canopy and over-lapping arrangement stabilizing ram, so as to the farthest lower machine height to satisfy the matching requirement of thin coal seam equip ment. Through the centralized control system of fully-mechanized working face and manpower centralized control center's remote control operation, the bidirectional cut ting coal could be realized automatially and the automatic mining of thin coal seam face came true.The shearer has been exploiting the thin coal seamof0.6~ 1. 3 m in Xuecun Mine of Fengfeng Group, which realized the centralized control of mine tunnels and automatic mining without manual operation in the mine face, with a mont hly production of 118 thousand tons and annual production of 1 million tons. The safe and high efficiency exploitation of thin coal seam could be achieved.
