摘要
为解决0.55 m厚的极薄煤层受空间限制难以实现综合机械化开采的问题,研发适应极薄煤层的新型综采液压支架及其采煤、运输设备,简化综采工艺,借助不同于较厚煤层的电液自动控制功能,实现行人空间与采煤机的合理变换,保证极薄煤层无人综采过程和设备维护合理空间布置,实现极薄煤层综合自动化采煤。
In order to solve the space limitation of the coal mining in the 0.55 m ultra thin seam and to solve the high difficuh problems of the fully-mechanized coal mining in the ultra thin seam, a new hydraulic powered support of the fully-mechanized coal mining, the coal mining and transportation equipment and the simplified fully-mechanized coal mining technique suitable for the mining of the ultra thin seam were researched and developed.With the electric and hydraulic automatic control function different to the thick seam, a rational alteration between the walking space and the coal shearer was realized to ensure the rational space layout for the unmanned fully-mechanized coal mining process in the ultra thin seam and the equipment maintenance.Thus the fully-mechanized automatic coal mining in the ultra thin seam was realized.
