摘要
针对ZF6000/17.5/28型放顶煤液压支架在"三软"煤层综放工作面使用过程中暴露出的问题进行技术改造,实践证明,改造后的液压支架更适应"三软"煤层的地质条件。
Aimed at the exposed problems of ZF6000/17.5/28 type hydraulic support applied at the fully mechanized caving face, in ＂three soft＂ coal seam, the technology reform is in progress. The practice proves that the reformed hyolraulic supports suit for the geologic condition of ＂three soft＂ coal seam.
