摘要
在充分总结国内外顺槽支护实践经验的基础上,结合沿空掘巷顺槽巷道的矿压分布特点,针对沿空掘巷顺槽巷道支护强度高、顶板破碎严重等关键及薄弱环节,设计了一套能够适应工作面沿空掘巷轨道顺槽支护生产条件的超前支护液压支架,避免对顶板的反复支撑,改善了轨道顺槽的支护问题。
The distribution of underground pressure in fully summarized and roadway on the basis of practical experience, combined along gob side of the roadway, along goal high for the roadway support intensity, seriously damaged the roof and other key weak link is designed to adapt to a face track along goal roadway production conditions ahead of hydraulic supports, improve the support of the track.
