摘要
利用锚索、锚注联合支护技术,提出对郑煤集团超化煤矿22水仓通道甩车场交叉点,在巷道断面大、地质条件差、压力大等复杂条件下矿工钢抬棚式支护交岔点的加固方案,进一步阐述了锚索、锚注支护机理和取得的显著效果。
By the anchor cable casting support technology, a strong plan of miner steel carrying shed casting support crossing to the crossing of water storehouse 22 is raised. The anchor cable casting support mechanism and notable effect are expourded.
