摘要
南山煤矿北五外区15层地质条件复杂,设计综放面全走向大坡度开采,通过对ZF2000/16/24轻型低位放顶煤液压支架的推拉千斤顶联接头、液压系统管路、以及安装护帮板等一系列技术改造和措施,顺利地实现了沿全走向大坡度开采。为今后在地质条件复杂的块段综放开采设计、生产提供开采经验和技术数据。
due to the complex geological conditions of the north - fifth outer region in Nanshan Coal Mine, designed the total - strike large slope mining technology in fully mechanized caving face, by a series of technology transformation and measures of push - pull jack joint in ZF2000/16/24 light low - roof coal hydraulic support, hydraulic system pipeline and sprag installation, successfully realized the total - strike large slope mining, and provided the mining experiences for the future mining design and production in complex geological conditions region of fully mechanized caving face.
