晋城3#煤采用6.8m高度支架的可行性研究

Feasibility Study on 6.8 m Height Bracket in A Coal Well in Jincheng

厚煤层一次采全高是一种经济合理的开采方法,液压支架作为综采工作面的核心设备,对井下煤炭开采有着举足轻重的影响,通过对现有的大采高支架特点和使用情况的研究,提出了研制使用更大采高液压支架的可行性,对煤层一次采全高高度增大进行了有益的探索。

Full-seam mining is an economic and reasonable method for a thick coal seam mining ,the hydraulic support is the core e-quipment in fully mechanized working face ,has a significant impact on the underground coal mining .Based on the characteristics and service conditon of the existing large mining-height support ,the feasibility of developing the larger mining-height suppotr is pro-posed ,to increase the mining height of coal seam .
