摘要
为研究工作面长度增加后的矿压显现规律,以某矿5312大采高300 m长工作面为工程研究背景,通过现场实测和对比分析的方式对5312工作面矿压显现规律进行研究,结果表明:工作面长度增加后,来压步距减小18%,超前支承压力峰值增大17.8%.
In order to study the law of strata behavior in larger width working face, the 300 m width 5312 working face is taken as the background of engineering research. The field strata behavior law is studied by means of field measurement and comparative analysis. The results show that the pressure step is reduced by 18%, and the advancing support pressure peak is increased by 17.8%.
