摘要
介绍了神东矿区榆家梁煤矿优越的地质条件和技术优势可以采用超长工作面,对合理煤柱宽度进行了模拟研究,得出煤柱越宽,弹性区越大,煤柱即越稳定,但要考虑到经济效益。最后得出合理煤柱宽度及工作面合理工作长度对井下支护设计具有借鉴意义,现场应用效果良好。
The paper introduce the supper long working face in Yu Jia Liang Mine.Comparing some kinds of length working face in technical economy.We study on the proper pillar width.We can conclude the more width the more stabilize.We should consider economic returns when we elect pillar width.At last we can know that proper working face length and pillar width,the effect of study is good.
