摘要
大采高综放工作面由于机采高度的加大,在给工作面生产带来便利的同时,也带来支架与围岩关系的变化。结合潞安王庄煤矿6203大采高综放工作面的具体条件,分析了大采高综放面支架的承载特性及其适应性。研究表明,支架承载的变化过程较复杂,支架总体位态良好,能够适应大采高综放工作面的围岩活动规律,保证了工作面的安全高效生产。
Because the increase of mining height in fully-mechinzed coal winning caving roof, it brings convenient and both brings the changing of rock rationlations. Combined the conditions of 6203 mining height fully-mechinzed coal winning caving roof working face in Wangzhuang Coal Mine,it analyzed support bear character and adaptability. The study indicated that the changing process of bear support is more complicated and it place state is fine, which is able to adapt the activity rule of rock and guaranteed safe and high - effect production.
