超长综放工作面的矿压显现规律研究

Research on Mine Pressure Behavior Regularity of Super-long Fully Mechanized Caving Coalface

以现场矿压观测资料为基础,结合矿山压力观测与控制的理论知识,对路天矿1604超长综放工作面的来压规律及特点进行了分析。得出超长综放工作面顶板来压在工作面方向出现不同步特征,老顶断裂步距较一般工作面小,超长综放面有别于普通综放面的来压特征,为今后设计、布置和回采类似工作面提供了科学依据。

The rule and characteristic of weighing of super-long fully mechanized caving coalface of open-pit mine 1604 are analyzed based on on-site mine pressure observation data and combine with the theory knowledge of observation and control of mine pressure.The result indicate that super-long fully mechanized caving coalface roof weighting show out-of-step characteristic on working face direction,old roof fracture drawing pace is less than of ordinary working face,weighing characteristic of overlong fully mechanized coal mining face is different from ordinary fully mechanized caving face,provide scientific basis for future design、arrangement and backstopping of similar working face.
