“三软”不稳定厚煤层综放工作面增加支架技术研究与应用

Study and Application of the Technique for Setting Additional Supports at Fully-mechanized Top-coal Caving Face in Unstable Thick Seam FeaturingSoft Coal,Roof and Floor Strata

介绍了在"三软"不稳定厚煤层综放工作面回采过程中,由于煤层倾角变化造成切巷长度增加后,所采用的增加液压支架及前后部输送机延伸的技术。

During themining of the face using fully-mechanized top -caving method, the oblique face length is seen to be increased due to variation of dip angle of seam. For better roof control in this case, measures are taken to set up additional hydraulic supports and extend the length of the fore and rear scraper conveyors
