“三软”煤层俯斜长壁综采工作面液压支架研制
Hydraulic support design for three-soft fully-mechanized longwall face to the dip
【摘要】 针对"三软"煤层工作面煤壁片帮严重、超前冒顶和支架易扎底等技术难题,设计研制了ZZ6400/18/38型四柱支撑掩护式液压支架,经过回采实践表明,该支架适应"三软"煤层工作面围岩条件,支架运行正常,工况良好。
【Abstract】 According to three-soft working face technical problems such as serious rib spalling,advance roof fall, support sinking and so on, ZZ6400/18/38 four -pillars chock-shield is designed and manufactured. The support runs well and working condition is good in course of mining, which shows the support is suitable for three-soft working face.
