据悉,山东新汶矿业集团华丰煤矿探索总结出的大断面岩巷快速掘进配套技术解决了制约快速掘进的主要问题,破解了难以实现高产、高效“双高”难题,填补了大断面岩巷快速掘进配套技术的空白。长期以来,掘进速度跟不上采煤速度是制约煤炭生产的主要问题。华丰矿应
It is reported that Huafeng Coal Mine of Shandong Xinwen Mining Group to explore the conclusion of the rapid excavation of rock tunnel supporting technology to solve the main problems restricting rapid excavation to solve the difficult to achieve high yield and high efficiency double high problems to fill a large section Rock tunnel rapid supporting technology blank. For a long time, the speed of boring can not keep pace with coal mining is the main problem restricting coal production. Huafeng mine should be
