急倾斜煤层综采工作面下端头支架支护技术应用

摘要

本文主要阐述急倾斜煤层坚硬顶板软煤软底综合机械化采煤工作面下端头支护过程中出现的问题，提出采用急倾斜煤层下端头横式液压支架支护技术，从设备选型，布置及操作工艺进行论述，解决了急倾斜煤层综采工作面下端头支护难题，为建设高产高效工作面奠定基础。%This paper mainly expounds the steeply inclined seam with hard roof, soft coal and soft bottom comprehensive mechanization min-ing coal working surface and the lower end of the supporting process problem, the steeply inclined coal seam and the lower end of the horizon-tal hydraulic support supporting technology, from the selection of equipment, layout and operation process is discussed, and solved the steeply inclined coal seam fully mechanized working face end support problem, in order to lay the foundation for the construction of high production and high efficient working face.
