摘要
内蒙古福城煤矿采掘接续紧张,沿空掘进巷道在掘进和工作面回采期间维护困难。在9煤工作面巷道布置矿压观测仪器,通过现场实测确定了9煤巷道变形特征,揭示了9煤沿空掘进巷道维护困难的原因,对矿井安全高效开采具有指导意义。
The excavation of Fucheng coalmine in Inner Mongolia was continued tightly, and it was difficult to maintain the gob-side entrydriving during tunneling and working face advancing. Through the observation of roadway in 9 coal face, the deformation characteristics of 9 coal roadway are determined by the observation method of site pressure. The cause of difficulty in maintenance of roadway along roadway 9 is revealed, which is helpful for mine safety and high efficiency mining. significance.
