摘要
以王庄煤矿 432 6超长综放工作面为例 ,对工作面加长以后综放支架的运转状况进行分析 ,评价其在超长综放条件下的适应性。文章指出 ,ZZP480 0 - 17/ 33F型支架基本适用于 432 6超长综放工作面整层放顶煤开采。通过采用双泵双回路供液等措施 。
Taking the extra long face NO 4326 with long wall top coal caving mining in Wangzhuang Coal Mine as an example, the paper analyzes the working state of the increasing face length, appraises its adaptation. The paper points out that Model ZZP4800-17/33F supports are basically suitable to the full seam mining.By the adoption of the two pump and two circuit system, a great increase of setting load of the support is made to enforce the stability control at the end face.
